rotate about active mixed with normal did not work as it did in 2.45, where the active edge could be used
as a rotation
axis (this is quite useful)

=======================
Caching and Baking:
- The point cache is now cleared on DAG_object_flush_update(), and not cleared for time dependency graph updates.
- There is now a Bake button instead of Protect. Also cache start and end frames were added to softbody and particles.
- The cloth autoprotect feature was removed.
- The Ctrl+B menu now also bakes cloth and particles next to softbody and fluids. Additionally there are now frree bake and free cache menu entries.
- The point cache api has been changed. There is now a PTCacheID struct for each point cache type that can be filled and then used to call the point cache functions.
- PointCache struct was added to DNA and is automatically allocated for each physics type.
- Soft body now supports Bake Editing just like cloth.
- Tried to make the systems deal consistently with time ipo's and offsets. Still not sure it all works correct, but too complicated to solve completely now.
Library Linking:
- Added some more warnings to prevent editing settings on library linked objects.
- Linked objects now read from the cache located next to the original library file, and never write to it. This restores old behavior for softbodies. For local simulation the mesh and not the object should be linked.
- Dupligroups and proxies can't create local point caches at the moment, how to implement that I'm not sure. We probably need a proxy point cache for that to work (ugh).
Physics UI:
- Renamed deflection panel to collision for consistency and reorganized the buttons. Also removed some softbody collision buttons from the softbody panel that were duplicated in this panel for cloth.
- Tweaked field panel buttons to not jump around when changing options.
- Tabbing e.g. Soft Body Collision into the Soft Body panel, it now only shows Collision to make the panel names readable.
- I tried to make enabled/disabling physics more consistent, since all three system did things different. Now the two modifier buttons to enable the modifier for the viewport and rendering are also duplicated in the physics panels. Toggling the Soft Body and Cloth buttons now both remove their modifiers.
- Fixed modifier error drawing glitch.
Particles:
- Particles are now recalculated more often than before. Previously it did partial updates based on the changes, but that doesn't work well with DAG_object_flush_update() ..
- Fixed memory leak loading keyed particle system. Now keys are not written to file anymore but always created after loading.
- Make particle threads work with autothreads.
Continue Physics:
- The timeline play now has a Continue Physics option in the playback menu, which keeps the simulations going without writing them to the cache.
- This doesn't always work that well, some changes are not immediately updated, but this can be improved later. Still it's fun to get a feel for the physics.
Todo:
- Point cache can get out of sync with and undo and changing a file without saving it.
- Change the point cache file format to store a version (so old point cache files can be either converted or at least ignored), and to do correct endian conversion.
- Menu item and/or buttons for Ctrl+B.
- A system("rm ..") was changed to remove() since the former is very slow for clearing point caches. These system() calls were already giving trouble in a bug in the tracker, but really most use of this system("") should be changed and tested.
- The Soft Body Collision and Clot Collision panel titles don't mention there's point cache settings there too, doing that makes them unreadable with the default panel setup.. but may need to make the names longer anyway.

=========
Merge of the famous particle patch by Janne Karhu, a full rewrite
of the Blender particle system. This includes:
- Emitter, Hair and Reactor particle types.
- Newtonian, Keyed and Boids physics.
- Various particle visualisation and rendering types.
- Vertex group and texture control for various properties.
- Interpolated child particles from parents.
- Hair editing with combing, growing, cutting, .. .
- Explode modifier.
- Harmonic, Magnetic fields, and multiple falloff types.
.. and lots of other things, some more info is here:
http://wiki.blender.org/index.php/BlenderDev/Particles_Rewrite
http://wiki.blender.org/index.php/BlenderDev/Particles_Rewrite_Doc
The new particle system cannot be backwards compatible. Old particle
systems are being converted to the new system, but will require
tweaking to get them looking the same as before.
Point Cache
===========
The new system to replace manual baking, based on automatic caching
on disk. This is currently used by softbodies and the particle system.
See the Cache API section on:
http://wiki.blender.org/index.php/BlenderDev/PhysicsSprint
Documentation
=============
These new features still need good docs for the release logs, help
for this is appreciated.

The 'Only Needed' option for Auto-Keyframing now works better with a few of the different transform options.
Rotating/Scaling using a pivot point that is not the center of the Object/Bone (3d-cursor, active), also inserts location keyframes if the location also changes. If "Only Centers" option is activated, then only location keyframes are inserted.

This commit fixes several bugs related to animating armatures. I've also tidied up the formatting in a few files along the way, and also commented the flags for this pose->flag.
What's new/fixed:
* Undo will no longer destroy entire un-keyframed poses. Now it behaves as expected, and only reverses the most recent change.
* On some files, POSE_DO_UNLOCK somehow got set on files and never cleared. The symptom of this was a file in which you suddenly could no longer pose an armature at all without using auto-keyframing. A check to prevent this from happening again has been added (it will also fix old files too)
Notes:
- Now, all PoseChannels get tagged with BONE_UNKEYED after they have been transformed. This flag prevents IPO data being flushed over these new values, even after undo.
- These tags only get removed on frame-changes or inserting new keyframes.
|
|
* Does not indicate that UV's exist, nor does it add UV's when used.
* Only accessible for texturepaint, vertexpaint and weightpaint from a button in the header (Paint Selection Mask)
* Not accessible from the mode menu, this is only an option that applies to paint modes.
This dosnt effect DNA, face select (G_FACESELECT) can be enabled at any time but is only used when paint modes are enabled.
Other changes
* UKey is uv unwrap in editmode, Ukey for undo was editmode only anyway.
* UVCalc in editmode adds a UV Layer if there is not one alredy.
* texture draw in editmode does not draw the face dots (they are get in the way of texturing)
* some missing updates were added.
* removed manipulator from when paint modes are enabled since the manipulator is not drawn in the 3d view.

Snap Cursor to Selected in EditMode for bone was still not working correctly. A missing check made it impossible to snap to joints in some situations.
|
|
After complaints from wavez, Snap Cursor to Selected for Bones in EditMode now results in the cursor being snapped to the midpoint of the selected joint(s) like it did before my no zero-length bones commit.
|
|
I've moved the Auto-Keyframing functionality out of the special_aftertrans_update function into two separate functions, which can be called independent of the Transform system. One is for Bones, while the other is for Objects.
This now means that the Shift-S Snapping Tools will now work with auto-keyframing.
|
|
- Dont do anything if no verts or faces are selected (used to zoom into 0,0,0)
- use the centers of dupli objects (should eventually use their bound boxes), much nicer when dealing with many dupli-objects

Preview Range now works in the IPO editor.
|
|
* colour -> color
* centre -> center
* normalise -> normalize
* modelling -> modeling
|
|
Preview Range is a useful tool for animating (espcially on longer timelines). It allows you to only run through a limited set of frames to quickly preview the timing of a section of movement without going through the whole timeline. It means you don't have to set/reset start/end frame for rendering everytime you wish to only preview a region of frames.
Hi Ton,
Attached is a patch (I know you've already got lots of them in the tracker ;-) ) for a feature that I've sometimes wanted. It seems that this sort of thing is supported in other packages, but I can't be sure.
Note: I may have left in a few bits and pieces I didn't mean to in the patch (this is off a source tree which had quite a few revisions in it, all of which was experimental)

* 'Ctrl P' in Action/NLA/Timeline sets preview range. Click+drag to form selection-box defining region of frames to preview
* 'Alt P' in Action/NLA/Timeline to clear preview range
* 'Pre' button beside Start/End fields in timeline toggles whether start/end fields refer to scene or preview
* 'Ctrl Rightarrow' and 'Ctrl Leftarrow' jump to start/end of preview region when it is set
* 'S' and 'E' set the start/end frames of preview region when it is set (just like normally) in Timeline only
* In Action/NLA editors, frames out of preview region are now drawn darkened when preview-region is set

Small but very annoying issue with modifiers meant that G.totvert/totedge/totface
were updated to reflect the effects of a subsurf modifier in object mode but all other
modifier types were ignored. This was not only inconsistent, but also made it very
difficult to keep track of poly budgets. Now in order to obtain accurate counts
object_handle_update is called immediatly after adding a modifier and precedes a call
to countall() which has been modified to query the final derived mesh directly
using dm->getNumVerts/Edges/Faces callbacks. Editmode behaviour is unchanged.

better support on low-end Macintoshes with integrated Intel graphics
chipsets. Patch received from "UncleZiev" on #blendercoders, but I
adjusted it so other video chipsets and platforms are unaffected.
The only visual difference is that on MacBook and iMac machines, the box
select outline is drawn with solid, not dashed lines like other platforms
and not invisible as they were previously.

Fixed bug #5773, retopo - if in wireframe mode should give an error/warning
* Show error message for Retopo All button if view is in wireframe mode
* When toggling view shading, update view depth data if shading isn't set to wireframe

I've often found it very annoying that with both ends of a bone selected,
they would both get snapped to the snapping point. This means that the bone
becomes zero-length, hence disappears from view and gets deleted upon
leaving editmode.
Now, when both ends of the bone are selected, only the head of the bone gets
snapped to the snapping point. The tail will get offset by the same amount
that the head gets offset by, thus preventing zero-length bones.
|
|
Bugfix for my previous snapping commit. In some cases, bones still
didn't snap correctly (parentless 'root' bones). That was because those
cases assumed that constraints had no effect on those bones.
|
|
Now the Snap To Location (Shift S) tools for bones in pose-mode
work correctly. Previously, only one of these tools was implemented,
but it only worked in some cases.
This fixes item #4874 in Todo Tracker. Was patch #5012.
|
|
- Proxy Armature: armature layer (visible bones) is now saved in proxy, so
on file reload the layer settings are restored
- bugreport: disabling subsurf (for view) didn't change the total amounts
in header.
|
|
Some operations like edge loop deselect would cause selection history
to become invalid. Added a sanity check to countall() to try and catch
these when they happen.
|
|
- All code is in #ifdef ... #endif
- Only make build system is supported and you have to add:
export WITH_VERSE=true
to user-def.mk file
- Blender can share only mesh objects and bitmaps now
- More informations can be found at wiki:

images (like used for rendering icons).
When working during Orange on new render pipeline, I've left this topic
alone for a while... subpixel precision testing is very time consuming and
needs concentration for a while. :)
This commit brings back precision as it was for 2.41. Below a short
explanation of the solved issues.
- the window matrix for rendering is kept constant during all OSA passes,
this to ensure clipping happens for each pass identically.
- a subpixel offset is only applied on filling in the z-buffer
- this offset is inverse corrected for shadepixel code, only on 2 places
Another nasty issue is that for filtered rendering (gauss etc), the tiles
(or entire image) is temporally increased 2 pixel in size. This caused a
'dark' (or sky color) edge on the rendering. During Orange that was solved
with a hardcoded clipping offset value, which only corrected for larger
pictures (like > 500 pixels in size).
Now this clipping offset is correctly calculated, based on render size.
Last issue: the view border in 3d window was calculated using integers,
giving small errors in display too. Now it uses float, so visually the
view border is more close to what a render shows.

As suggested, adding Page Up and Page Down to the hotkey list to change the size of the circle of selection, using brush select (BB).
This is done to bring it in line with transform's PET size adjustment.
Two hotkeys to rule them all and to the reference manual binds them... :P
|
|
Added code to make 'Collapse Edges' handle UV's intelligently. This seems to work in just about every case that I can test, so it's turned on by default.
Also completely removed the 'collapse faces' command and code. I'm not sure what I was thinking with this in the first place since edge collapse does the same job while in in face mode. Because of this there is now just one single command that covers both situations called 'Collapse' which uses the edge collapse code.
|
|
Added the following to the 'select' menu of 3d header and toolbox while in mesh editmode: '
-Path Select
-Edge Loop Multi-Select
-Edge Ring Multi-Select
-Loop to Region
-Region to Loop
Also added Collapse Faces and Collapse Edges to menu and toolbox as well as made them available in selection modes other than face exclusive and edge exclusive.
|

Previously Blender did not store the order in which vertices, edges
or faces were selected in edit mode. In many cases it is useful to
have this data, however it is not desirable to store every selection
made. Now blender stores selections in the order in which they were
made in a linked list called 'selected' in EditMesh. EditSelection structs
are created whenever 'EM_store_selection' from editmesh_lib.c is called
(currently only on user selection with mouse). There are several cases
in which they might be deallocated by calling the 'EM_remove_selection'
function however:
-When the user deselects something with the mouse ('mouse_mesh' in
editmesh_mods.c)
-When switching selection modes stored selections that are not relevant
to the new mode are removed by the 'EM_strip_selections' function
(multi-select mode is supported)
-When the vertex, edge or face pointed to by a certain stored selection is
deallocated
-When EM_clear_flag_all is called and where the flag passed to the function
contains the 'SELECT' bitmask.
-When leaving edit mode (making stored selection data persistent across
editing sessions will require modifications to mesh DNA later)
Todo:
There are a few cases still where you can temporarily end up with a stored
selection that points to an element that is no longer selected
(edge loop de-select can cause this for instance). The solution to this is to
add a call to EM_remove_selection from 'EM_select_edge' and 'EM_select_face' when
these functions are being used to deselect elements. For the sake of completeness
however this will also require that an 'EM_select_vert' function be coded and
called at all appropriate parts of the editmesh code. I will look into this
later in the week.
For now there are two tools that already take advantage of the stored selections.
The first one is 'merge at first or last vertex' in the merge menu (the 'firstvert' and
'lastvert' pointers are gone from EditMesh). The second tool is path select, which builds
a path between the last vert selected and the second to last vert selected. This allows you
to build complex path selections in a short amount of time like this
'select A, select B, path select. select C, path select. select D...'
|
|
to my previous commit (whoops). The second part covers the changes I
have made to the code since then (all related to merge tools code).]
# Part One: Complete Log for Commit from 2/13/06
-> Upgraded merge tools.
The new merge tools add several options to blenders Merge submenu,
accessed via the WKEY whilst in Editmode for meshes. The new options
depend on current mode:
- Vertex mode: "At First" and "At Last"
When choosing "At First" or "At last" it will merge all selected
vertices at the first or last selected vertex.
(Note: Blender now keeps track of the last and first verts selected in
editMode (G.editMesh->lastvert and G.editMesh->firstvert
pointers. This meant additions were made to the undomesh code in
editmesh.c as well).
- Edge mode: "Collapse Edges"
When choosing this option, Blender examines the current set of
selected edges and groups them according whether or not they are
topologically connected. It then goes through each group and merges
them one by one to a single point.
- Face Mode: "Collapse Faces"
Works the same as "Collapse Edges", only works on groups of
topologically connected faces.
-> Inclusive selection mode conversion.
This feature extends the ability of blenders selection mode
conversions. Currently when you change selection modes from a "lower
order" mode to a "higher order" one (vertex->edge, vertex->face or
edge->face) blender only selects elements in the new mode whose
elements were completely selected in the previous mode.
This patch does not change blenders default behavior but offers
implicit selection mode conversion as an alternative. To access it,
hold either the left or right CTRL keys and click on a selection mode
in the view 3d selection mode header buttons. This can be accessed via
the CTRL-TAB selection mode switching as well, simply hold CTRL while
clicking the mode you want or entering its number on the keypad.
In some programs, such as Wings and Mirai, it has been demonstrated
that it can also be very useful to exploit selection mode switching to
implicitly select previously unselected elements as well. For instance
switching selection mode from vertex to edges will select all edges
currently associated with the currently selected vertices. The same
behavior is applied to switching between vertex->face and
edge->face. By exploiting this sort of selection conversion complex
selection sets can be built quicker.
Furthermore I modified blenders UndoMesh code to make selection mode
switching "undo coherent". Aside from its relevance to inclusive
selection mode conversion, this really counts as a "bug" in my
mind. Previously selection mode switch could cause the selection state
of the mesh to be invalid when certain modeling operations were
undone. An example of this would be "edge subdivide-> switch to face
mode-> undo"; you end up with edges selected while still in face mode!
# Part Two: Log for this Commit
-> Code Cleanup
As per Ton's request I reformatted all my code, changed variable names
and eliminated my use of "LinkNode" structs and replaced them with
"ListBase" instead. There should be no warnings while compiling now
either.
-> Remove doubles bug
Fixed small problem in removedoublesflag() in editmesh_tools.c that
caused editface structs to get their UV's scrambled. Vertex colors
might not be safe though? Need to investigate later.
-> Small bug in in the the code for merge last/first
It could cause a crash when exiting editmode, switching meshes, then
entering editmode again. "lastvert" and "firstvert" pointers are now
set to NULL whenever exiting editmode now (see load_editmesh() in
editmesh.c). I will find a better solution to this *soon*...
-> All merge tools now UV aware (optional)
The default behavior is to leave UVs alone, but if you hold CTRL while
clicking on the menu entry, UV's are merged. This works fine in most
situations, although some investigation into how to best handle
merging of UVs at the border of UV islands needs to be done.
This last item brings up a point about the current state of the
interface: several functions accessed through the WKEY menu now use
the CTRL modifier to change how they behave (This convention has been
in place for a while, see subdivide for example). Unfortunately there
is no way to communicate the way modifier keys change the behavior of
certain functions to the user. This makes such options invisible for
all intents and purposes...

Key isnt needed anymore in Blender or python.
Changed Pythons Object.Duplicate() to take keyword parms to enable duplication of spesific data.
Eg- Object.Duplicate(mesh=1) # to duplicate mesh data also.
|
|
********* Node editor work:
- To enable Nodes for Materials, you have to set the "Use Nodes"
button, in the new Material buttons "Nodes" Panel or in header
of the Node editor. Doing this will disable Material-Layers.
- Nodes now execute materials ("shaders"), but still only using the
previewrender code.
- Nodes have (optional) previews for rendered images.
- Node headers allow to hide buttons and/or preview image
- Nodes can be dragged larger/smaller (right-bottom corner)
- Nodes can be hidden (minimized) with hotkey H
- CTRL+click on an Input Socket gives a popup with default values.
- Changing Material/Texture or Mix node will adjust Node title.
- Click-drag outside of a Node changes cursor to "Knife' and allows to
draw a rect where to cut Links.
- Added new node types RGBtoBW, Texture, In/Output, ColorRamp
- Material Nodes have options to ouput diffuse or specular, or to use
a negative normal. The input socket 'Normal' will force the material
to use that normal, otherwise it uses the normal from the Material
that has the node tree.
- When drawing a link between two not-matching sockets, Blender inserts
a converting node (now only for value/rgb combos)
- When drawing a link to an input socket that's already in use, the
old link will either disappear or flip to another unused socket.
- A click on a Material Node will activate it, and show all its settings
in the Material Buttons. Active Material Nodes draw the material icon
in red.
- A click on any node will show its options in the Node Panel in the
Material buttons.
- Multiple Output Nodes can be used, to sample contents of a tree, but
only one Output is the real one, which is indicated in a different
color and red material icon.
- Added ThemeColors for node types
- ALT+C will convert existing Material-Layers to Node... this currently
only adds the material/mix nodes and connects them. Dunno if this is
worth a lot of coding work to make perfect?
- Press C to call another "Solve order", which will show all possible
cyclic conflicts (if there are).
- Technical: nodes now use "Type" structs which define the
structure of nodes and in/output sockets. The Type structs store all
fixed info, callbacks, and allow to reconstruct saved Nodes to match
what is required by Blender.
- Defining (new) nodes now is as simple as filling in a fixed
Type struct, plus code some callbacks. A doc will be made!
- Node preview images are by default float
********* Icon drawing:
- Cleanup of how old icons were implemented in new system, making
them 16x16 too, correctly centered *and* scaled.
- Made drawing Icons use float coordinates
- Moved BIF_calcpreview_image() into interface_icons.c, renamed it
icon_from_image(). Removed a lot of unneeded Imbuf magic here! :)
- Skipped scaling and imbuf copying when icons are OK size
********* Preview render:
- Huge cleanup of code....
- renaming BIF_xxx calls that only were used internally
- BIF_previewrender() now accepts an argument for rendering method,
so it supports icons, buttonwindow previewrender and node editor
- Only a single BIF_preview_changed() call now exists, supporting all
signals as needed for buttos and node editor
********* More stuff:
- glutil.c, glaDrawPixelsSafe() and glaDrawPixelsTex() now accept format
argument for GL_FLOAT rects
- Made the ColorBand become a built-in button for interface.c
Was a load of cleanup work in buttons_shading.c...
- removed a load of unneeded glBlendFunc() calls
- Fixed bug in calculating text length for buttons (ancient!)

In Armature Pose-bone panel, the 'hide' button got replaced with a button
where you can type (TAB complete works) a name for a Mesh Object. It then
draws that Object instead of the indicated bone drawing type.
Fixes for bone layers:
- Akey in Editmode didnt work proper (now deselects all non visible bones
too. selection for editmode works on the vertices, not bones...
- Snap in Editmode now respects layers
|
|
- Bone Ghost drawing now skips axes and names
- "Snap to cursor" now works for parent-less bones in PoseMode
- Prevented assigning in buttons of negative zero (was confusing)
|
