this layer is now also used for various preview tasks in Object mode.
“Cleanup” commit, no functional changes.

The VBO index type can be either ushort or uint depending on the grid
size. The comparison was checking how many quads are in the array, but
this was incorrect; the size of the index elements should depend on
the maximum value they reference, i.e. the maximum coord/normal
element.
|
|
Forgot to use return value of function creating the index buffer.
|
|
Also changed show-in-border key to SHIFT+H as suggested by Daniel
Salazar.

All multires grids have exactly the same ordering, so rather than
allocate a new index buffer for each PBVH node, just allocate one that
can be reused for every grid.
This requires more draw calls (one per grid rather than one per PBVH
node), but less graphics memory.

|
also remove large, duplicate comments from sunsky.h

There are still fairly bewildering set of callbacks being tossed
around, but it's at least a little less verbose now.

Previously, the shading and material was set once per PBVHNode when
drawing. This is still the case, but PBVHNodes are now built to
contain only one material and shading mode.
This is done with an extra partitioning step; once the number of
primitives in the node falls below the PBVH leaf limit, it's
primitives are checked for matching materials. If more than one
material or shading mode is present in the node, it is split and
partitioned (partitioned by material rather than 3D location.)
Given a sufficiently 'annoying' input, like a dense mesh with
thousands of materials randomly scattered across it, this could
greatly increase PBVH build time (since nodes might end up containing
a single primitive), but in general this shouldn't come up.
In order to support materials for grids, the CCGDM is building another
grid array (of DMFaceMat structs). This could be used to replace
CCGDM.faceFlag for some small memory savings (TODO).

This function pointer isn't called anymore, so removing it and the
cddm/ccgdm/gpu code associated with it.

- spelling - turns out we had tessellation spelt wrong all over.
- use \directive for doxy (not @directive)
- remove BLI_sparsemap.h - was from bmesh merge IIRC but entire file commented and not used.

When set to solid-shading, GPU_update_grid_buffers was calling
normal_quad_v3 to output into a mapped buffer, but normal_quad_v3
reads as well as writes.
This fix actually makes a huge performance difference with my drivers
(Gallium/Radeon).

the node muting system as well.
There are a number of features that use a kind of "internal linking" in nodes:
1. muting
2. delete + reconnect (restore link to/from node after delete)
3. the new detach operator (same as 2, but don't delete the node)
The desired behavior in all cases is the same: find a sensible mapping of inputs-to-outputs of a node. In the case of muting these links are displayed in red on the node itself. For the other operators they are used to relink connections, such that one gets the best possible ongoing link between previous up- and downstream nodes.
Muting previously used a complicated callback system to ensure consistent behavior in the editor as well as execution in compositor, shader cpu/gpu and texture nodes. This has been greatly simplified by moving the muting step into the node tree localization functions. Any muted node is now bypassed using the generalized nodeInternalRelink function and then removed from the local tree. This way the internal execution system doesn't have to deal with muted nodes at all, as if they are non-existent.
The same function is also used by the delete_reconnect and the new links_detach operators (which work directly in the editor node tree). Detaching nodes is currently keymapped as a translation variant (macro operator): pressing ALTKEY + moving node first detaches and then continues with regular transform operator. The default key is ALT+DKEY though, instead ALT+GKEY, since the latter is already used for the ungroup operator.

- use GL_TRUE/FALSE for glLightModeli
- use set for python checks against multiple string values.

Disabled double-side lighting by default and changed areas which are using
double sided lighting to switch it off just after doing stuff which requires
double side.
This makes code a bit more simple to follow (no all that disabling double side
lighting all over the code and so).
This change also fixes crash of blender caused by intel gme965 driver which
leads to stack corruption in some place when double side lighting isn't
disabled (probably driver still kind of using double side in some areas or so).
Hopefully it'll also fix #30293: Converting Text to Mesh
Thanks to Campbell to assist writing this patch!

At the point where GPU_build_mesh_buffers is called, the
face_vert_indices map has already been built; it contains the same
data in an easier-to-access format.

non-multires meshes.
As with multires, this change calculates face normals rather than
using vertex normals when the node is flat-shaded.
Flat-shading with VBO on non-multires meshes is still wrong, but
fixing that would require larger changes to our vertex buffers.
|
|
Building the mesh buffers already gets the PBVH_UpdateDrawBuffers flag
set, so this was double-updating the vertex buffer.

viewport/ the Nyan cat bug.
Issue is caused by scaling for power of 2 dimensions and mipmapping that happens through GLU. It looks like the library cannot handle float colour values above 1.0 correctly. Since we are close to release I will just clamp the srgb result for now even though it will result in a small performance loss for 16 bit textures only.
I tried a few things before that, glGenerateMipmaps + no scaling (supported for 2.0 GL hardware and up), or using our own scaling instead of glu among them which worked very nicely and gave a speedup too. However, since we are close to release and there may be issues with GPU mipmap generation, see:
http://www.gamedev.net/topic/495747-another-glgeneratemipmap-question/
(old discussion but better be sure than sorry)
I went for the most compatible solution. Maybe after release this can be tested if other devs agree.

the image texture is missing. The flag to indicate that the mipmap levels were
already loaded into GPU memory was incorrectly set then.

later, like srgb_frect or ftilerect on or must not be freed, like Imbuf array itself.

ATI/Apple cards with broken non-power-of-two-textures missed some cards,
checked against list of GL_RENDERER values, hopefully complete now.
|
|
|

got out of sync with node changes.
|
|
|

support in some older cards, now it does a more precise check for problematic
cards so that it can be enabled on new cards that do support it properly.

This issue is caused by texelFetch which does not take wrapping options into account as it uses unnormalized uv coordinates to access a texel. A hack was made to do manual wrapping in the shader. This is acceptable because texture wrap mode is always treated as "repeat" elsewhere in 3D view in blender.
Thanks to Morten Mikkelsen for pointing out the cause of the issue and providing the fix.

=========================
Documentation: http://wiki.blender.org/index.php/User:Psy-Fi/UV_Tools
Major features include:
*16 bit image support in viewport
*Subsurf aware unwrapping
*Smart Stitch(snap/rotate islands, preview, middlepoint/endpoint stitching)
*Seams from islands tool (marks seams and sharp, depending on settings)
*Uv Sculpting(Grab/Pinch/Rotate)
All tools are complete apart from stitching that is considered stable but with an extra edge mode under development(will be in soc-2011-onion-uv-tools).

fix for sequencer unique naming which was missed with string length update.
|
|
- 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).
