Remove from blender/nodes, collada, blenfont & render.
|
|
Strip unindented comment blocks - mainly headers to avoid conflicts.
|
|
also comment debug prints for raytracing

caused by rBec4ed2e3df507245aceb7341b4fdf2f5ed935067.
Easy mistake in code cleanup. :)

- minf, maxf, mini, maxi --> min_ff, max_ff, min_ii, max_ii
|
|
|
|
|
|
had a typo too.
|
|
|
|
DO_MIN/MAX re-reading same value from array 4 times when it can do once (use minf rather then MIN2, same for maxf)

--debug
--debug-ffmpeg
--debug-python
--debug-events
--debug-wm
This makes debug output easier to read - event debug prints would flood output too much before.
For convenience:
--debug-all turns all debug flags on (works as --debug did before).
also removed some redundant whitespace in debug prints and prefix some prints with __func__ to give some context.

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

These should not have any effect on render results, except in some cases with
you have overlapping faces, where the noise seems to be slightly reduced.
There are some performance improvements, for simple scenes I wouldn't expect
more than 5-10% to be cut off the render time, for sintel scenes we got about
50% on average, that's with millions of polygons on intel quad cores. This
because memory access / cache misses were the main bottleneck for those scenes,
and the optimizations improve that.
Interal changes:
* Remove RE_raytrace.h, raytracer is now only used by render engine again.
* Split non-public parts rayobject.h into rayobject_internal.h, hopefully
makes it clearer how the API is used.
* Added rayintersection.h to contain some of the stuff from RE_raytrace.h
* Change Isect.vec/labda to Isect.dir/dist, previously vec was sometimes
normalized and sometimes not, confusing... now dir is always normalized
and dist contains the distance.
* Change VECCOPY and similar to BLI_math functions.
* Force inlining of auxiliary functions for ray-triangle/quad intersection,
helps a few percentages.
* Reorganize svbvh code so all the traversal functions are in one file
* Don't do test for root so that push_childs can be inlined
* Make shadow a template parameter so it doesn't need to be runtime checked
* Optimization in raytree building, was computing bounding boxes more often
than necessary.
* Leave out logf() factor in SAH, makes tree build quicker with no
noticeable influence on raytracing on performance?
* Set max childs to 4, simplifies traversal code a bit, but also seems
to help slightly in general.
* Store child pointers and child bb just as fixed arrays of size 4 in nodes,
nearly all nodes have this many children, so overall it actually reduces
memory usage a bit and avoids a pointer indirection.

MAKE_ID, FILE_MAXDIR, moved the generic defines to BLI_utildefines.h.
no functional changes.

This time it works! (gcc and mingw can handle compile and link)
|
|
*Disabled ray counter (can be enabled on render/extern/include/RE_raytrace.h by commenting out the define)
*marked bvh_node_merge() as static inline (hopping it now compiles on gcc and mingw)
|
|
* Made bvh_node_merge() in svbvh.h static (fix suggested by jaguarandi). This makes mingw link again.
* Also, patched my previous fix for ... = {}; since mingw didn't like the other fix (which was for msvc).
|
|
* mingw almost compiles again cleanly, except for a linking error when linking blender http://www.pasteall.org/8297
* win64 should compile again too to a similar degree?
* silenced warnings about no newlines...

(this is a generalization of some of the experimental stuff i tried during SoC,
but only had time to improve a few days ago)
- it should yield slightly better results
- the cost model can somehow be tweaked to optimize for diferent trees.
*cleaned up some code
*added counters for number of SIMD BB tests
*added GPL license block on missing files
|
|
-separated vbvh, svbvh, qbvh in diferent files (before the only way to switch between them was at compile time)
|
|
|
|
|
|
groupped childs (for SIMD)
*SIMD support for the first 4*N childs of each node
*Some bvh code organized
