Edit Mesh:
- Added back "Edge Shortest Path select"
It now also does regular selection, more fun!
It's mapped to CTRL+click now, and makes or clears selections
between current and previously activated edge.
Seam/Sharp/etc marking is a toolsetting mode still. These
options cannot become properties easily, because the tool
uses the properties of selected edge to clear...
- Removed a whole bunch of G.f flags, related to mesh drawing.
It's all now local in me->drawflags. Here's the list of
removed old globals:
G_DRAWEDGES
G_DRAWFACES
G_DRAWNORMALS
G_DRAW_VNORMALS
G_ALLEDGES
G_HIDDENEDGES
G_DRAWCREASES
G_DRAWSEAMS
G_DRAWSHARP
G_DRAWBWEIGHTS
G_DRAW_EDGELEN
G_DRAW_FACEAREA
G_DRAW_EDGEANG

- remove Verse support. This will be brought back in The Future (probably jiri + me)
This means 5k lines less in blenkernel.
- fix two small errors for global cleanup, now compiles properly with FFMPEG enabled too.

So, editmode mesh is back! :)
At the moment only TABkey works and mouse select, 1 vertex at a
time. More will follow of course.
Note for the devs:
- G.editMesh has been removed, be careful with old code.
- EditMesh now is property of Mesh itself
Although it means unlimited editmodes, for migration purposes we
better stick to 1 "obedit" per scene, which is in Context too
- G.obedit will get removed soon, so use CTX_data_edit_object(C)
Or if you can't, just scene->obedit for now
- Also removed the CTX_data_edit_mesh(), this has no meaning
anymore. EditMesh is not context senstitive anymore, only the
edit-object for time being is.
- Martin: I've already tucked some EditMesh pointer in T and
removed all G.editMesh there.

because the TFace flag was not always easy to access from editmode.
using the last selected face was almost good enough however when selecting verts and edges the last selected face would become inactive and the space image would flicker about too much.
The active face is used for getting the space image at the moment and keeps scripts that use this flag working also.
This has 2 commands to get and set, so the variable is not accessed directly.
all "UV Calculate" scripts work now
last commit crashed when in solid draw mode, it seems subsurf modifier is ignoring the displayMask since MTFACE is available. just made it do a null check for now.
uvcalc_follow_active_coords.py - should be done inC and put in the snap menu.
|
|
|
|
header_view3d.c was doign an implicit declaration also.
|
|
Copying texture space from Mesh to Curve crashed. Bad code. cleaned up.
|
|
All data layers, including MVert/MEdge/MFace, are now managed as custom
data layers. The pointers like Mesh.mvert, Mesh.dvert or Mesh.mcol are
still used of course, but allocating, copying or freeing these arrays
should be done through the CustomData API.
Work in progress documentation on this is here:
http://mediawiki.blender.org/index.php/BlenderDev/BlenderArchitecture/CustomData
Replaced TFace by MTFace:
This is the same struct, except that it does not contain color, that now
always stays separated in MCol. This was not a good design decision to
begin with, and it is needed for adding multiple color layers later. Note
that this does mean older Blender versions will not be able to read UV
coordinates from the next release, due to an SDNA limitation.
Removed DispListMesh:
This now fully replaced by DerivedMesh. To provide access to arrays of
vertices, edges and faces, like DispListMesh does. The semantics of the
DerivedMesh.getVertArray() and similar functions were changed to return
a pointer to an array if one exists, or otherwise allocate a temporary
one. On releasing the DerivedMesh, this temporary array will be removed
automatically.
Removed ssDM and meshDM DerivedMesh backends:
The ssDM backend was for DispListMesh, so that became obsolete automatically.
The meshDM backend was replaced by the custom data backend, that now figures
out which layers need to be modified, and only duplicates those.
This changes code in many places, and overall removes 2514 lines of code.
So, there's a good chance this might break some stuff, although I've been
testing it for a few days now. The good news is, adding multiple color and
uv layers should now become easy.

- 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:
http://mediawiki.blender.org/index.php/BlenderDev/VerseIntegrationToBlender
http://mediawiki.blender.org/index.php/BlenderDev/VerseIntegrationToBlenderUserDoc
I hope, that I didn't forget at anything

Stored selections now get saved to mesh library blocks as direct data.
The idea that stored selections are 'erased' when leaving editmode and
switching objects is pretty mysterious for the user. Note that currently
the mselect array in a mesh is not written to file. Not sure whether
to change this or not.
|
|
- Mark Border Seam: mark edges on the border of face selection as seam.
- Clear Seam: clears seams in selected faces.
Hotkey: Ctrl+E
- Alt+RMB Click: mark/clear edge as seam
- Alt+Shift+RMB Click: mark/clear seams along the shortest/straightest path
from last marked seam. The cost of the path also includes some measure of
'straightness' next to the typical distance to make things work more
predicatble and edgeloop friendly. Note that this cuts a path from edge to
edge, not vertex to vertex. That gives some nice control over the direction
of the seam.
Also includes:
- Removed old LSCM code.
- Fix updates glitches with DerivedMesh/Subsurf drawing in FaceSelect mode.
Now there's a drawMappedFacesTex instead of drawFacesTex.
- Minimize Stretch menu entry called Limit Stitch.
- Removed the lasttface global, was being set before it was used anyway, so
might as wel return from a function.
- Moved some backbuf sampling code to drawview.c from editmesh, so it can be
used by Faceselect and VPaint.
- Use BLI_heap in parametrizer.c.

- added decimate modifier & removed old decimate interface
(currently lacks warning about destroying data, and there needs
to be a way for modifiers to return errors back to the interface)
- allow applyModifier to return NULL to indicate error
- unfortunately new decimate modifier means it does not know exact
number of faces in mesh (other modifiers may come before) and so
instead interface uses a percentage. if people need exact face
count slider then I will have to think of some hack to fit this
in. note that it does display the output face count so its possible
to tweak the pct to get what you want regardless.
- removed python Wave object
If you are bored now how much easier it is to implement something
like decimate as a modifier. Very few changes to interface, very
few entry points.
|
|
- changed mesh_modifier, sbObjectStep, object_deform to take vertexCo
argument instead of operating on mesh
- fixed bug where a derived mesh would not be returned in editmode
- removed object_wave, replaced by init_wave_deform and calc_wave_deform
- moved cached DerivedMesh to Object, not Mesh... fixes heisenbugs
with linked objects
|
|
builds new DerivedMesh... caching can come later)
- split DerivedMesh returning functions into editmesh and mesh groups
- got rid of DL_NORS displist type (get built on fly for mesh when
needed)
- got rid of Mesh.disp (yay!)
- started to punch DerivedMesh returning functions into shape to introduce
modifier stack
|
|
- switch renderer to store orco's in a hash table instead of
caching in mesh (I don't like the renderer caching data
in the actual mesh structure)
- added mesh_create_orco[_render] function
|
|
|
|
- removed ME_CCG_SUBSURF define
- dropped CCGSubSurf from editing menu... subsurf is always
CCG now.
NOTE: If you saved a file with CCGSubSurf set on the button
will show up blank (will still work as a subsurf). Just change
type back to Catmull-Clark.
Wave bye-bye to HyperMesh...
|
|
- added G.editMesh->derived pointer... idea is to use this
for mesh derived from editmesh instead of Mesh->derived (as the
derived mesh tends to vary depending on what it came from).
This part could be cleaner, also there may problems with it not
being invalidated correctly.
- And most importantly: In case people were beginning to worry all
these edits were just crazy zr stuff, the big point comes about:
Incremental subsurf calculation is now enabled. This gives massive
speed improvements when editing a large mesh.
For the eye-candy happy: try setting G.rt==52 before entering editmode
and the edges and vertices (in optimal mode) will switch to displaying
visually the age since a region has last been calculated. Lots of
fun!
|
|
- removed DL_MESH displist type!!!! Now store a DerivedMesh directly.
- May still be some issues left having to do with releasing this
at the right time (old code just splashed free_displist all
over the place).
|
|
only in one C file and not worth dropping in extern but presumably
will be synced with public CCGSubSurf release I hope to be making
soon.
- Currently the implementation must be enabled by defining
USE_CCGSUBSURFLIB somewhere with your build system. The code should
be considered highly experimental.

Implementation Least Squares Conformal Maps parameterization, based on
chapter 2 of:
Bruno Levy, Sylvain Petitjean, Nicolas Ray, Jerome Maillot. Least Squares
Conformal Maps for Automatic Texture Atlas Generation. In Siggraph 2002,
July 2002.
Seams: Stored as a flag (ME_SEAM) in the new MEdge struct, these seams define
where a mesh will be cut when executing LSCM unwrapping. Seams can be marked
and cleared in Edit Mode. Ctrl+EKEY will pop up a menu allowing to Clear or Mark
the selected edges as seams.
Select Linked in Face Select Mode now only selects linked faces if no seams
separate them. So if seams are defined, this will now select the 'face group'
defined by the seams. Hotkey is still LKEY.
LSCM Unwrap: unwrap UV's by calculating a conformal mapping (preserving local
angles). Based on seams, the selected faces will be 'cut'. If multiple
'face groups' are selected, they will be unwrapped separately and packed in
the image rectangle in the UV Editor. Packing uses a simple and fast
algorithm, only designed to avoid having overlapping faces.
LSCM can be found in the Unwrap menu (UKEY), and the UV Calculation panel.
Pinning: UV's can be pinned in the UV Editor. When LSCM Unwrap is then
executed, these UV's will stay in place, allowing to tweak the solution.
PKEY and ALT+PKEY will respectively pin and unpin selected UV's.
Face Select Mode Drawing Changes:
- Draw Seams option to enable disable drawing of seams
- Draw Faces option to enable drawing of selected faces in transparent purple
- Draw Hidden Edges option to enable drawing of edges of hidden faces
- Draw Edges option to enable drawing of edges of visible faces
The colors for these seams, faces and edges are themeable.

Edges in Mesh
- adds automatic when you use creases. For other situations; call the
void make_edges(Mesh *me) in mesh.c. Of course, once in editmode the
edges are automatically recreated.
- in F9 buttons you can add/remove edges too
- both for Mesh and DisplistMesh, so it speeds up drawing quite some in
wireframe
- render for edges can't work... edges have no material nor tface nor col..
so here still the faces are rendered in wire
Creases in Subsurf
- based on the code by Chris McFarlen
- main changes is that now edges are used, saving quite some data in file
- use SHIFT+E in editmode to set edges-sharpness. values go from 0-1
- in F9 buttons you can set draw-crease mode. It draws now blended from
wire color to edge-select color (as provided in Theme)
Known issue: setting sharpness on 1 cube (subdiv 2) gives weird results
with some values... Chris, can you check?
Further; code cleanups, changing 0 in NULL when needed, no warnings, etc etc

New is that objects can have a force field, and Meshes can even deflect
(collide) particles. This is in a new sub-menu in Object buttons F7
The full instructions where on the web, Leon mailed it me and I will put
it in CMS tomorrow. For those who like to play with it now, here are demo
files:
http://download.blender.org/demo/test/
Quite some changes where in the integration though... so previous created
particle deflectors will not work. Changes to mention now are:
- gravity is renamed to 'force field'
- force field and deflector options are in Object now, not in Mesh
- the options also have its own struct, doesnt add to Object by default
- force fields are possible for all object types, but only work on center.
So empty objects are typical for it.
Work to do:
- add draw method in 3d win to denote forcefield objects
- check on the UI (panel with different size?)
- add 'recalc' button in deflector panel

2.25 like physics.
[SCons] Build with Solid as default when enabling the gameengine in the build process
[SCons] Build solid and qhull from the extern directory and link statically against them
That was about it.
There are a few things that needs double checking:
* Makefiles
* Projectfiles
* All the other systems than Linux and Windows on which the build (with scons) has been successfully tested.
|
|
(MVert,MFace,etc) off into DNA_meshdata_types.h, to isolate areas
of source that actually edit mesh *data* vs. areas that just edit
mesh object information.
|
|
* Created a MESH_MAX_VERTS macro in DNA_mesh_types.h
* fixed vert limit for converting displistmesh ==> mesh
* fixed vert limit when doing boolean operations
|

of zr). This struct was never written to file and the new 'int based'
MFace can be used in it's place. Some removal of redundant code could
perhaps be done now (I didn't do any though, just "s/MFaceInt/MFace/").
|
|
different objects shouldn't share flags this way (still sharing of
other mesh flags in renderer... ickity pickity, but I'm not fixing now)
- removed some unnecessary uses of DNA_mesh_types.h
|
|
Paves way for additional subsurf types, and avoids confusion
where Simple is on, but Subsurf is off.
|
|
yet (R.vn and R.vlr no longer exist, and were needed to get the image mapped
right). Works esp. well with Subsurfs. Sensitive to vertex normal issues
in Simple and Mesh modes.
-Also porting Simple Subdivide. Subdivides mesh at rendertime w/o changing
shape, for smooth displace and Radiosity.
-Removed an unused var from KnifeSubdivide.
|
|
The maximum vertex count for a mesh has been raised from 65000 to
2000000000L (yep, 2 billion!).
Please test!

thus also preserved over exiting/entering editmode (is this desirable?)
Can be turned off easily ...
- "Half-fixes" lost UV info problem with undo. I couldn't get it to
crash or lose UV info anymore, but we now have a memory leak (me->tface).
Ton, please check this!

when using linked-duplicated mesh, with subsurf and tfaces (UV texture)
the render crashed.
Found out the renderloop makes a new displaylist for each Mesh, also when
it is linked multiple times. That way pointers to previous created elements
in displaylists become invalid. Crash!
Result now it even renders faster for linked-duplis. :)
|
|
can be found under the 'SubSurf' button.
Optimal drawing only shows the subdivided original edges. Quite nice!
And; it's a load faster!
- to evaluate: do we want this in editmode too?
|
|
|
|
So we should be all set now :)
