Those files are still not in use (SCons will tyr to compile new CCGSubSurf files
but no code will be in use at all because those new files are fully wrapped by
ifdef WITH_OPENSUBDIV check).
|

This is a preparation commit for having OpenSubdiv integrated into Blender
and new layout is the following:
- CCGSubSurf.c contains implementation of common functions used by both
legacy subdivisions code and by the new code in the future.
- CCGSubSurf_inline.h contains internal functions which are to be inlined
due to the performance reasons. Those functions are only ment to be used
bu CCGSubSurf* files.
- CCGSubSurf_intern.h contains declarations of private functions and data
structures used by CCGSubSurf module.
- CCGSubSurf_legacy.c contains legacy implementation of subdivision algorithm.
- CCHSubSurf_util.c contains utility functions which are not directly related
on the subdivision code (i.e. debug functions, hash implementation etc).
There should be no functional changes so far.

It was always only using the flags from the first source layer of a given type, not from
the layer actually being handled.
This was (probably) more or less harmless for the CD_FLAG_NOCOPY test,
but could be really bad when checking CD_FLAG_NOFREE, and when
copying the flags over to new copied data!

don't support VBOs.
Exposed by initialization error in GLEW, which should be fixed
seperately.
|
|
|
|
Also 'com' as abbreviation for center-of-mass is a bit confusing, rename to 'center'.

Patch D1417 by Martin Felke, with minor edits thanks!
|

Code was actually skipping setting color selection indices and previous
commit actually broke mask selection in texture painting.
All should work now.

This commit implements point density texture for Cycles shading nodes.
It's done via creating voxel texture at shader compilation time, Not
totally memory efficient, but avoids adding sampling code to kernel
(which keeps render time as low as possible), In the future this will
be compensated by using OpenVDB for more efficient storage of sparse
volume data.
Sampling of the voxel texture is happening at blender side and the
same code is used as for Blender Internal's renderer.
This texture is controlled by only object, particle system and radius.
Linear falloff is used and there's no turbulence. This is because
falloff is expected to happen using Curve Mapping node. Turbulence
will be done as a distortion on the input coordinate. It's already
possible to fake it using nose textures and in the future we can add
more proper turbulence distortion node, which then could also be used
for 2D texture mapping.
Particle color support is done by Lukas, thanks!

It is rather annoying attitude nowadays to use const qualifier all over the
place, including using it for multi-dimensional arrays. This isn't really
supported in GCC prior to version 5.0 because it considers such an arrays
to be a "pointer to a const pointer" which gives implicit casting errors.
It's not possible to disable this particular type of warnings treated as
errors in any GCC version prior to 5.0 as well, meaning currently usage of
-Werror globally in Blender code is not possible at all.
This commit makes it possible to use -Werror in areas which are complaint
with older GCC versions. New advanced CMake options are:
- WITH_COMPOSITOR_WERROR
- WITH_LIBMV_WERROR
- WITH_CYCLES_WERROR

Instead only create MFace layer when its requested

gives the index of a vertex in a looptri

Easy one, we don't draw quads anymore. Also normal
didn't use polygon index

Classic integet overflow/size_t substitution case. Machines are getting
powerful enough to easily expose these kinds of error now.

Sculpting w/ subsurf crashed
|
|
Since many callers only need a single triangle
|
|
This stores loop indices into the loop array giving easier acess
to data such as vertex-colors and UV's,
removing the need to store an MFace duplicate of custom-data.
This doesn't yet move all internal code from MFace to LoopTri just yet.
Only applies to:
- opengl drawing
- sculpting (pbvh)
- vertex/weight paint
Thanks to @psy-fi for review, fixes and improvements to drawing!

Our 'unit epsilon' was too small, given the fact we only display up to four digits usually...
|
|
|
|
Issue was caused by deform vert layer existing in the mesh.
Solved in quite simple way, but it still might be missing
some other layers.
Any custom data experts around to check if it's correct?

Remove legacy code completely, now dyntopo, multires et al even work on
GL 1.1 for really hardcore users :p
Real purpose here though is to be able to have fast multires drawing
even with VBO off, since it requires using indices for vertex buffers.
Also made own code elf puke an eaten normal update function which
made multires not update normals in solid mode...sorry.
|

Get rid of legacy drawing, it's only used for selection,
in which case we can prepare a temporary color buffer and draw
at once. Code is not complete here because we still redundantly
set the draw color in the draw function and don't ommit hidden
faces automatically. Still it works 100% without immediate mode
now.
|

Silly oversight on the viewport patch
|
|
Also avoid multiple float->short conversions for the same normal.
|
|
- use void instead of float for array arg (cast in the switch statement)
- remove unused args
- use const for poly-mapping and user_data args

This patch changes the way we draw meshes by introducing
indexed drawing. This makes it possible to easily
upload and rearrange faces ad lib according to any criteria.
Currently we use material sorting but textured sorting and
hiding will be added to optimize textured drawing and skip
per face testing.
It also adds support for vertex buffers for subsurf
modifiers (Except from GLSL drawing), making drawing of
subsurf much faster without need for bogus modifiers.
Tests show that we gain approximately 20-25% performance
by that for solid mode drawing with up to 50% gains for
material drawing. Textured drawing should also have a
small performance gain, but more substantial optimizations
are possible there.
