brushes, due to issues with color coded drawing or slow/buggy reading from such
a buffer on some systems.
In case multisample is enabled now, it uses an offscreen buffer for such drawing,
which is not multisampled and so should not cause issues. This does mean there is
some extra GPU memory usage when multisample is enabled, and we could optimize
triple buffer to work together here somehow to share buffers, but it's better than
having selection not working.

* Rename functions and move to own header.
* Add wrapper functions for glLight.
* Auto detect if we can use faster code for solid lighting.
* Various fixes for textured draw mode.

code is still unused, but the intention is to use this to solve the double sided
lighting problem on NVidia, and to make the materials work on OpenGL ES 2.0
eventually.
The code works and matches the fixed function lighting pretty much exactly, but
still needs optimizations. The actual integration in object draw will be
committed later when more fixing & testing, there's lots of different combinations
and unclear OpenGL state here.

Full log is here:
http://wiki.blender.org/index.php/Dev:Ref/Release_Notes/2.66/Usability#Matcap_in_3D_viewport
Implementation notes:
- Matcaps are an extension of Solid draw mode, and don't show in other drawmodes.
(It's mostly intended to aid modeling/sculpt)
- By design, Matcaps are a UI feature, and only stored locally for the UI itself, and
won't affect rendering or materials.
- Currently a set of 16 (GPL licensed) Matcaps have been compiled into Blender.
It doesn't take memory or cpu time, until you use it.
- Brush Icons and Matcaps use same code now, and only get generated/allocated on
actually using it (instead of on startup).
- The current set might get new or different images still, based on user feedback.
- Matcap images are 512x512 pixels, so each image takes 1 Mb memory. Unused matcaps get
freed immediately. The Matcap icon previews (128x128 pixels) stay in memory.
- Loading own matcap image files will be added later. That needs design and code work
to get it stable and memory-friendly.
- The GLSL code uses the ID PreviewImage for matcaps. I tested it using the existing
Material previews, which has its limits... especially for textured previews the
normal-mapped matcap won't look good.

not do correct partial updates, now it remembers if the opengl texture is a
non-color data texture or not and takes that into account for the update.
Also includes some renaming ncd => is_data for consistency with color space
terminology used elsewhere.

without the underscores these clogged up the namespace for autocompleation which was annoying.

- use more logical names for strings, noticed too many strings called `str` when reviewing name patch.
- pass __func__ macro to uiBeginBlock(), quite a few names were wrong (copy/paste error).

This commit extends limit of ID and objects to 64 (it means 63 meaning
characters and 1 for zero-terminator). CustomData layers names are also
extended.
Changed DNA structures and all places where length constants were hardcoded.
All names which are "generating" from ID block should be limited by MAX_ID_NAME-2,
all non-id names now has got own define called MAX_NAME which should be used all
over for non-id names to make further name migration stuff easier.
All name fields in DNA now have comment with constant which corresponds to
hardcoded numeric value which should make it easier to further update this
limits or even switch to non-hardcoded values in DNA.
Special thanks to Campbell who helped figuring out some issues and helped a lot
in finding all cases where hardcoded valued were still used in code.
Both of forwards and backwards compatibility is stored with blender versions newer
than January 5, 2011. Older versions had issue with placing null-terminator to
DNA strings on file load which will lead to some unpredictable behavior or even
crashes.

This commit introduces bicubic bump map capabilities for the viewport for OpenGL 3.0+ capable GPUs.
To use the functionality change the bump mapping method to "best quality"
Previous "best quality" setting becomes "medium quality" now.
For non OpenGL 3.0 GPUs this becomes the same as "medium quality"
Also:
* added tooltip descriptions to the bump method settings.
* modified the shader to ommit extraneous matrix multiplications for matrices already provided by OpenGL.
Bicubic shader by Morten Mikkelsen. Thanks a lot!
Oh...and FIRST!

"The Blender Foundation also sells licenses for use in proprietary software under the Blender Licens"
also remove NaN references from files that have been added since blender went opensource.

shader = gpu.export_shader(scene,material)
Returns the GLSL shader that blender generates to produce the visual effect
of material in scene for the purpose of reusing the shader in an external engine.
This function is meant to be used in a material exporter so that the GLSL
shader can be exported entirely. The return value is a dictionary containing the
shader source code and all associated data.
The full documentation is under sphinx.
Warning: there has been an API between the patch and this commit:
uniform['lamp'] and uniform['image'] now return python reference to
ID block instead of ID name as before. The X3D exporter that uses this
function must be adapted.

we cant ensure that a requested buffer can be allocated so report opengl errors when failing to allocate the buffer (rather then printing to console).
this is common enough and generic error isn't too helpful to users.

'const char's,.
Only one functional change where Transform orientations passed "" to BIF_createTransformOrientation() which could then have the value written into.

- fixed bug in paste material, exposed by stricter warnings.
- removed/renamed various shadowed vars.
- removed BGE lamp.colour, only allow lamp.color attribute.

some problems (especially in the freeing function). I will research an alternative solution and submit it to the tracker.

OpenGL viewport render gave squeezed results in cases.
Reason: some graphics cards only give offscreen buffers in multiples
of 256 or 512 (my case).
Current fix uses the actual size returned by graphics card, which
is also safe for too large renders.
More elaborate cropping or matching is for another time.
(Added printf for feedback on this, might disappear)

is currently only used in the profiling data of the BGE.
Here is a image of it in action:
http://www.pasteall.org/pic/show.php?id=6351
What it monitors:
* VRAM used by textures created via bf_gpu and BL_Textures
What it does not monitor:
* VRAM used by the Blender ui
* VRAM used by 2d filters
* VRAM allocated by the user via KX_Scene.pre_draw and KX_Scene.pre_draw

e.g. thousands of colors on OS X, due to use of uninitialized value. Problem
tracked down and patch provided by Shane Ambler, thanks!

set the draw method to triple buffer or overlap depending on the
configuration. Ideally I could get all cases working well with triple
buffer but it's hard in practice. At the moment there are two cases
that use overlap instead:
* opensource ATI drives on linux
* windows software renderer
Also added a utility function to check GPU device/os/driver.
|
|
I tried to make it integrate more with regular render but couldn't
do it well, it still needs a 3D view to take the settings from, and
can't run in a separate thread due to OpenGL.
However, it is now rendering to an offscreen buffer which then gets
displayed in the image window. This requires FBO's to be available, so
a fallback creating a new window is still needed. Currently available
from the Render menu in the top header.

a system crash and other issues on ATI/Apple, due to a buggy driver
(similar issues reported for other OpenGL applications). For now, work
around it by not using non-power-of-two textures on this combination.
|

* cache for low res (deactivating high res for now)
* new way of view3d rendering of smoke (no longer 3 axes) -using 3dtexture now (introduced into gpu/intern)
* introducing LZO and LZMA libs into extern (makefiles missing for now)
* reducing memory usage after simulating for the frame ended (freeing temporary buffers)
* splitting smoke into 2 modifier for the cache-sake (it cannot handle more than 1 cache on the same modifier-index)
* no color on gui anymore
* fixing non-power-of-2 resolutions (hopefully)
* fixing select-deselect of domain drawing bug
* fixing drawobject.c coding style (making Ton happy) ;-)
HINT #1: If scons doesn't work -> cmakefiles are up-to-date, couldn't test scons (but i tried to mantain them, too)
CODERS HINT #1: we really need a way to disable adding all modifiers through "Add Modifiers" dropdown!
WARNING #1: before applying this commit, deactivate your SMOKE DOMAIN in your old files and save them then. You can open them then savely after that.
WARNING #2: File and cache format of smoke can be changed, this is not final!

various functions instead.

* Drawing code from wm_event_system.c split into separate wm_draw.c file.
Now there's 3 different draw methods implemented, not sure what survives
or will be added but is useful for debugging.
* Draw All: redraws everything each time, for reference.
* Draw Overlap All: what the code did before this commit, only draw
regions marked for redraw, and anything that overlaps them.
* Triple Buffer: copies/retores all area regions into a texture, and
blits that before drawing. Menus, brushes, gestures, etc are redrawn
always on top of that.
Currently "Draw Overlap All" is set hardcoded to be used still. Triple
Buffer code is not complete, it doesn't handle window resize yet. Cards
that don't support non power of two textures can need quite large
textures as well, this could be split into multiple smaller ones.

using linking together the precompiled library shader code and
material code and recompiling it all again for each material even
if it gives a performance hit, since the previous workaround only
worked on some driver versions still.

the features that are needed to run the game. Compile tested with
scons, make, but not cmake, that seems to have an issue not related
to these changes. The changes include:
* GLSL support in the viewport and game engine, enable in the game
menu in textured draw mode.
* Synced and merged part of the duplicated blender and gameengine/
gameplayer drawing code.
* Further refactoring of game engine drawing code, especially mesh
storage changed a lot.
* Optimizations in game engine armatures to avoid recomputations.
* A python function to get the framerate estimate in game.
* An option take object color into account in materials.
* An option to restrict shadow casters to a lamp's layers.
* Increase from 10 to 18 texture slots for materials, lamps, word.
An extra texture slot shows up once the last slot is used.
* Memory limit for undo, not enabled by default yet because it
needs the .B.blend to be changed.
* Multiple undo for image painting.
* An offset for dupligroups, so not all objects in a group have to
be at the origin.
