Render:
- New; support for dual CPU render (SDL thread)
Currently only works with alternating scanlines, but gives excellent
performance. For both normal render as unified implemented.
Note the "mutex" locks on z-transp buffer render and imbuf loads.
- This has been made possible by major cleanups in render code, especially
getting rid of globals (example Tin Tr Tg Tb Ta for textures) or struct
OSA or using Materials or Texture data to write to.
- Made normal render fully 4x32 floats too, and removed all old optimizes
with chars or shorts.
- Made normal render and unified render use same code for sky and halo
render, giving equal (and better) results for halo render. Old render
now also uses PostProcess options (brightness, mul, gamma)
- Added option ("FBuf") in F10 Output Panel, this keeps a 4x32 bits buffer
after render. Using PostProcess menu you will note an immediate re-
display of image too (32 bits RGBA)
- Added "Hue" and "Saturation" sliders to PostProcess options
- Render module is still not having a "nice" API, but amount of dependencies
went down a lot. Next todo: remove abusive "previewrender" code.
The last main global in Render (struct Render) now can be re-used for fully
controlling a render, to allow multiple "instances" of render to open.
- Renderwindow now displays a smal bar on top with the stats, and keeps the
stats after render too. Including "spare" page support.
Not only easier visible that way, but also to remove the awkward code that
was drawing stats in the Info header (extreme slow on some ATIs too)
- Cleaned up blendef.h and BKE_utildefines.h, these two had overlapping
defines.
- I might have forgotten stuff... and will write a nice doc on the architecture!

to allow up to 2500 objects (was 500).
Still an arbitrary limit, could use better code. For now its less
frustrating :)

all the same. The latter two didnt take aspect ratio of windows into account
|
|
in edit mode.
Small extra fix; selection (mouse) on armature points goes easier now
(larger accepted distance from mouse pointer)

----- Killed UI frontbuffer draw
The interface toolkit was drawing all live updates (while using menus/buttons)
in the frontbuffer. This isn't well supported cross-platform, so time to be
killed once. Now it uses *only* glReadPixels and glCopyPixels for frontbuffer
access.
Live updates or menus now are drawn in backbuffer always, and copied to
front when needed.
NOTE: it was tested, but needs thorough review! On PC systems I suspects
backbuffer selection to screw up (check!). On SGI/SUN workstations it
should work smooth; but I need evidence
----- Smaller fixes;
- AA fonts were garbled on ATI systems. Now the AA fonts are drawn exact
on pixel positions. Needs the new FTGL libb too, patch is on maillist
- Rounded theme uses antialiased outlines
- Pulldown and popup menus have nice softshadow now
- New button type 'PULLDOWN', thats the one that callsup a pulldown menu.
Should be added to themes, as is the full menu/pulldown drawing
- Screendump for 1 window does the full window now, including header
- Empty pulldowns (for example running blender without scripts) give no
drawing error anymore
For review & fun;
- added curved lines as connectors, for Oops window
|
|
- borderselect draws cleaner info in bottom/left corner window
- OGL render (in view3d header) option didn't work on successive renders.
was due to removing hack that reopened the window each time. But now it
needed to be assigned correctly to blender's 'mywindow' system.
|
|
- Zbuffer clipped selection
Based on same algos as for drawing (blender polygon offset) vertices, edges
and faces now are clipped for draw and selection when Zbuffer is used.
Note that it works for endpoint vertices of edges, and for facecenters.
Also works for border and circle-select
- Optimal draw subsurfs
This now draws optimal with faces and edges selected/unselected, hiding the
original 'cage' (mesh) completely.
TODO: edge select, which still uses original (invisible) edge.

I patched this into instinctive a long time ago when someone submitted
the math to the mailing list but never got heard.
I hope it's acceptable :)

- "Global Pivot": Maintains a global Pivot and Align mode setting for
all 3d views when enabled, instead of seperate settings per 3d view
- "Auto Perspective": Switch to ortho mode automatically on 1/3/7, and
to Perspective when the view is rotated with the mouse
- "Align mode": As suggested on the list, when enabled, transformations
on several objects only transform their locations, not their sizes or
rotations.
- Grid dotted when not 1:1
***ATTENTION***! The User Interface parts of these features have not been
committed, as I work on my own modified UI here. The three features need
toggle buttons to turn them on and off.
I used the following 3 buttons (first two features are in userprefs,
third as a 3d view setting):
uiDefButBitS(block, TOG, USER_AUTOPERSP, B_DRAWINFO, "Auto Persp",
(xpos+edgespace+(3*medprefbut)+(3*midspace)+smallprefbut+2),y3+10,smallprefbut,buth,
&(U.uiflag), 0, 0, 0, 0,
"Automatically switch between orthographic and perspective");
uiDefButBitS(block, TOG, USER_LOCKAROUND, B_DRAWINFO, "Global Pivot",
(xpos+edgespace+(4*midspace)+(4*medprefbut)),y3+10,smallprefbut,buth,
&(U.uiflag), 0, 0, 0, 0,
"Use global pivot setting for all 3d views");
uiDefIconButS(block, TOG|BIT|10, B_AROUND, ICON_ALIGN,
xco+=XIC,0,XIC,YIC,
&G.vd->flag, 0, 0, 0, 0, "Translate only (align)");
Someone needs to add these to the interface in an appropriate manner!
Thanks.

types:
- Continue: is default, old style
- Dolly: is like previous, but not continuous
- Scale: is the new method. Name is based on fact it scales view

mouse.
For me it's a good replacement, and more intuitive & compatible. Now
let's wait for the storm of reactions...
|
|
This more of a quality issue... changes now are:
- in (ortho) 3d view, changing window aspect keeps zooming
level (it zoomed out with extreme portrait aspect)
- pressing 'home' in 3d window now shows all with extreme aspect ratios too
|
|
Justin will come with separate option to choose for 'automatic clipping', not
based on the vd->dist value, but something smarter... needs more work.
|
|
in you couldn't see all the geometry (correctly).
|
|
Also added USER_* to each define located in DNA_userdef.h.

- New lamp type added "Area". This uses the radiosity formula (Stoke) to
calculate the amount of energy which is received from a plane. Result
is very nice local light, which nicely spreads out.
- Area lamps have a 'gamma' option to control the light spread
- Area lamp builtin sizes: square, rect, cube & box. Only first 2 are
implemented. Set a type, and define area size
- Button area size won't affect the amount of energy. But scaling the lamp
in 3d window will do. This is to cover the case when you scale an entire
scene, the light then will remain identical
If you just want to change area lamp size, use buttons when you dont want
to make the scene too bright or too dark
- Since area lights realistically are sensitive for distance (quadratic), the
effect it has is quickly too much, or too less. For this the "Dist" value
in Lamp can be used. Set it at Dist=10 to have reasonable light on distance
10 Blender units (assumed you didnt scale lamp object).
- I tried square sized specularity, but this looked totally weird. Not
committed
- Plan is to extend area light with 3d dimensions, boxes and cubes.
- Note that area light is one-sided, towards negative Z. I need to design
a nice drawing method for it.
Area Shadow
- Since there are a lot of variables associated with soft shadow, they now
only are available for Area lights. Allowing spot & normal lamp to have
soft shadow is possible though, but will require a reorganisation of the
Lamp buttons. Is a point of research & feedback still.
- Apart from area size, you now can individually set amount of samples in
X and Y direction (for area lamp type 'Rect'). For box type area lamp,
this will become 3 dimensions
- Area shadows have four options:
"Clip circle" : only uses a circular shape of samples, gives smoother
results
"Dither" : use a 2x2 dither mask
"Jitter" : applys a pseudo-random offset to samples
"Umbra" : extra emphasis on area that's fully in shadow.
Raytrace speedup
- improved filling in faces in Octree. Large faces occupied too many nodes
- added a coherence check; rays fired sequentially that begin and end in
same octree nodes, and that don't intersect, are quickly rejected
- rendering shadow scenes benefits from this 20-40%. My statue test monkey
file now renders in 19 seconds (was 30).
Plus:
- adjusted specular max to 511, and made sure Blinn spec has again this
incredible small spec size
- for UI rounded theme: the color "button" displayed RGB color too dark
- fixed countall() function, to also include Subsurf totals
- removed setting the 'near' clipping for pressing dot-key numpad
- when you press the buttons-window icon for 'Shading Context' the context
automaticilly switches as with F5 hotkey
Please be warned that this is not a release... settings in files might not
work as it did, nor guaranteed to work when we do a release. :)

Main target was to make the inner rendering loop using no globals anymore.
This is essential for proper usage while raytracing, it caused a lot of
hacks in the raycode as well, which even didn't work correctly for all
situations (textures especially).
Done this by creating a new local struct RenderInput, which replaces usage
of the global struct Render R. The latter now only is used to denote
image size, viewmatrix, and the like.
Making the inner render loops using no globals caused 1000s of vars to
be changed... but the result definitely is much nicer code, which enables
making 'real' shaders in a next stage.
It also enabled me to remove the hacks from ray.c
Then i went to the task of removing redundant code. Especially the calculus
of texture coords took place (identical) in three locations.
Most obvious is the change in the unified render part, which is much less
code now; it uses the same rendering routines as normal render now.
(Note; not for halos yet!)
I also removed 6 files called 'shadowbuffer' something. This was experimen-
tal stuff from NaN days. And again saved a lot of double used code.
Finally I went over the blenkernel and blender/src calls to render stuff.
Here the same local data is used now, resulting in less dependency.
I also moved render-texture to the render module, this was still in Kernel.
(new file: texture.c)
So! After this commit I will check on the autofiles, to try to fix that.
MSVC people have to do it themselves.
This commit will need quite some testing help, but I'm around!

It already centered on selected objects outside of editmode, so this is just a consistency feature.
|
|
When joining 2 unconnected control points in Curve/Surface (FKEY) Blender
crashed.
Was just assuming in this code that a knots vector array was there...
simple fix!
BTW: I think Theeth discovered here the oldest Blender ever, I could
track it back to old Traces code from 1992. :)

colors. This because of the pretty weird (ab)use of load & make editmesh...
For each added undo step, the load_editmesh was fed with an empty mesh
to assign data to, without knowledge of what was in the original mesh.
That way UV and color data got lost.
Solved it in 2 steps:
1. removing the ->tface pointer from EditVlak, and make TFace a builtin
struct inside EditVlak. This didnt cost much extra mem, since it already
stored UV and color. This enabled some pretty cleanup in editmesh.c as
well, storing tface pointers was cumbersome.
2. for each undo step, it then generates always a tface and mcol block to
link to the undo Mesh.
Even when it wasn't in the actual Mesh, at exit editmode the original
Mesh is used as reference anyway, and undo-meshes are freed correctly.
The enormous commit is because I had to change the BLI_editVert.h file, and
found it was included in about every file unnecessary. I removed it there.
ALso found out that subsurf has code ready (unfinished) to make UV coords for
the displaylist in EditMode as well, nice to know for later...

all calls to ortho2 with correctness offset of 0.375 instead of 0.5.
this efficiently solves bug in drawing UV lines as reported.

3d window...
|
|
new code that manages multiple matrices for 'overlay' buttons.
just forgot to add call persp(PERSP_VIEW);
|
|
- uses callback mechanism to tell main drawing routine what to do
- for that reason it doesn't use frontbuffer drawing anymore
and it shows up in all 3d windows as well
- it uses the same colors as for the grid axes (I tweaked it a bit,
this is based at themecolors, and also should work in different
background and grid color)
- I disabled drawing lines through every object or every vertex.
The current display method is clear and not distracting
- when in 'local' transform (double press X/Y/Z), it displays a nice
axis in the center of transform for vertices.
In object-mode, local transform differs per object, so constraint lines
and axes are drawn for each individually...
Also:
- fixed an old bug in rotate transform(). Using a constraint for
rotation (X, Y, Z) didn't work for multiple objects at all!
|
|
This is only usefull for rotate now, but the axis constraining code has a part that depended on this, so I commit this part first.
For coders:
void constline(float *center, float *dir, int col)
Draw an infinite line on the screen. col is the color argument. It must be cpack compatible
void project_short_infiniteline(float *vec, float *dir, short *adr1, short *adr2);
clips infinite line to screen border

- changed the BIF_DrawString() function. it used to work different for
AA fonts as for default fonts. Now it's identical. Setting color for fonts
can just be done with OpenGL, for both font types.
Removed: BIF_DrawStringRGB()
- added theme color options for Buttons
- recoded DefButton, so it automatically chooses the right color.
- had to remove a 1000 uiBlockSetCol() calls for that reason...
- uiBlockSetCol() still works, to override automatic color
- removed entirely the silly old color system (BIFColorID). All color
calls can now be done with a BIF_ThemeColor() call, including fonts and
buttons and opengl stuff
- all buttons in button header have headercolor by default
- recoded drawing icons, it was a really bad & old loop doing manually
colorshading and blending... which was per pixel a load of code!
Now it uses a single OpenGL call to blend or colorize. Quite faster!
- (as test, for review) icons don't colorize anymore with button color,
but have a different alpha to blend in (when not active)
- recoded the entire interface_draw.c file...:
- drawing buttons is separated in three parts:
1. main drawing function for text and icons
2. free definable callback for button itself
3. free definable callback for slider
- removed a load of redundant code for this!
- coded a minimal theme, and adjusted Matt's buttons to match new
callback system
- adding new drawing themes is piece of cake now
- for coders, default 'themes' to be aware of:
UI_EMBOSS : the themable drawing style
UI_EMBOSSP: the pulldown menu system (apart from color not themable)
UI_EMBOSSN: draw nothing, only text and/or icon
UI_EMBOSSM: minimal theme, still in use for Logic and Constraintsa
this can be set with uiBlockSetEmboss(block) or in the uiNewBlock() call.
TODO: make UI API call for button alignment
(plus removed another series of warnings from code...)
Plus: fixed bug in Matts commit: he used a 'short' button for an 'int'

I had to clean up very old calls to switch matrices for 3d windows.
To make it more clear, I've introduced defines for the infamous persp()
function:
persp(PERSP_WIN); sets matrices at pixel level window
persp(PERSP_VIEW); restores matrices back to 3d drawing
persp(PERSP_STORE); only called once, to store correct matrices
I will now check on frontbuffer drawing of vertices... it's very doubtful
if it's used still correctly, was only meant for visual speed in the
early nineties you know. :)

message on Bf-committers for description.

in addition aligns and positions it so that it exactly "sees" the former
View3d.
|

"Waste cpu while rotating view"
I added a tiny idle in the 'wait_for_statechanged' call, I suspect
ghostwinlay returns events while holding mousebutton...
|
|
instead of drawing everything again, in all windows, it restricts to
the active and previous active object. when there are more objects to
be redrawn, it does a normal swapbuffers.
Result is it all redraws & selects a lot faster in complex scenes
* Little fix in "BallTable" routine when moving mouse vertical out of
the 3d window.
|
|
In fact, I made it working different, much more cooler!
-------The BallTable Method TM (patent pending)------------
This is a hybrid of the old turntable method (a virtual camara that rotates
around a table) and the trackball method. Mouse moving horizontal, gives
the turntable effect, but with vertical movement it works like a trackball.
So, vertically moving in the middle of the window exactly mimics old
turntable method, moving vertically in the window edge gives a 'twist'
rotation.
Try the turntable for fun! (is in user settings menu)
|
|
Might be possible I mised an .h or so, just notify me in that case.
|
|
#ifdef HAVE_CONFIG_H
#include <config.h>
#endif
Just need to finish cpp files now :)
