* Removed compiler warnings from texteditor work
* Added round brackets around the new defines for IPO channels for extra texture layers
* Tweaked priorities so that BLI_heap_* functions in blenlib can be found by linker (split-sources specific)
TODO:
* "monkey*" vars cannot be found 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.
It was building incorrect trees when there was only 1 leaf.
Code fixed to always generate a tree with at least 1 branch.. since most of bvh code relies on this.
*Made nearest surface also use "quad" bvh tree (instead of splitting quads in 2 bvh nodes).
Again that leaded to improvements in build and query time.
*BLI_bvhtree_find_nearest api is now following the same concept as BLI_bvhtree_ray_cast
removed code relative to bvhtree_from_mesh_tris.
Somehow it didnt finished and didnt added some files under the svn control
(found thanks to lguillaume that reported some files were missing)
Last merge fixed and also merged modifications up to revision 15584.
I checked the diff
svn diff --new . --old https://svn.blender.org/svnroot/bf-blender/trunk/blender
And everything seems to be right now
Its now faster than raytree (both on build and query)
Things tryed:
X=>Y=>Z=>X split (reduces build time.. but increases query time)
bucket sorts
(initial sorts for fast usage of bucket take a long time)
(nth is linear.. so its quite fast already)
Best times archieve with:
*usage of 4-ary trees.. reduces build time and tree size but didnt decreased query time
*quads are on the same node instead of splitting in 2 tris..
(this actually turned on speedup on query time.. since tree size is reduced by a factor of 2)
*test ray-bb before ray-primitive gives better times on both tris and quads
Notes:
measures where made projecting a sphere from inside the head of suzanne.
small bvh fixes:
*allow to create any tree type >= 2
*save split axis
changed shrinkwrap to perform normal cast with raytree and bvh tree and print both times:
Shrinkwrap (OBCube)24578 over (OBSuzanne)504482
target = raytree_create_from_mesh(calc->target): 1260.000000ms
shrinkwrap_calc_normal_projection_raytree(&calc): 1850.000000ms
tree = bvhtree_from_mesh_tri(calc->target): 3330.000000ms
shrinkwrap_calc_normal_projection(&calc): 3780.000000ms
On general query time is bit smaller on bvh tree..
but the build time of bvh is pretty big.
(build time can be removed from both if a cache system is added)
But I am still trying to see how fast I can make the bvh build
