- Some big refresh issues with softbody & cloth point cache usage should now be fixed.
- Removed sticky objects from particles (better stuff will come back when I get to updating reactor particles).
- Some initial easy memory efficiency cleanup for ParticleData struct. The ultimate goal is to get particles less memory hungry -> more particles possible in single scene.
- Wrong path timing clamping caused hair particles to seem disappeared when changing between normal<->hair particles.
- "Calculate to current frame" in cache buttons baked instead of the intended function.
- Boids particle data is now a bit better organized.
Now there is (in order of speed):
* Nearest neighbour (very rough quality)
* Linear (medium quality)
* Quadratic (good quality)
* Cubic Catmull-rom (very good quality, crisp)
* Cubic B-spline (very good quality, smooth)
Thanks!
shr->spec values could be greater then 1.0, causing negative color when using (1.0-shr->spec[i]) as a blending factor.
When shr->spec[i] is 1.0 the mircol is ignored, so only mix the mircol when needed (like clamping the spec).
* Fix for plane material preview render. Now, light cache aborts if there isn't enough volume, and falls back on non-cached single scattering. It still doesn't make much sense to render a plane as a volume, but for now in the preview it will shade the region in between the plane and the checker background.
Also, made the Outliner's horizontal scrollbar work better for keymaps view. It's still using an approximation of the width, but at least you can scroll now.
Note that With libsndfile also need libflac and libogg here (Linux), right
now I just add this two librarys to the NAN_SNDFILELIBS, but maybe
it's better split this ? (NAN_FLAC/NAN_OGG)
Finally in 2.5 branch :)
Still things to do, but will continue working in here. I won't bother
repeating the commit messages from the last year or so, however I've
written up some technical docs to help Ton/Brecht/etc review and find
their way around the code:
http://wiki.blender.org/index.php/User:Broken/VolumeRenderingDev
That above page has some known issues and todos listed, but I'm still
interested in bug reports.
Credits for this code:
* Matt Ebb
(with thanks to Red Cartel/ProMotion Studios)
* Raul Fernandez Hernandez (Farsthary) for patches:
o Light cache based multiple scattering approximation
o Initial voxeldata texture code
o Depth Cutoff threshold
* Andre Susano Pinto for BVH range lookup addition
* Trilinear interpolation adapted from pbrt
* Tricubic interpolation from libtricubic
This solves one of the last remaining hurdles for
volume rendering. Previously it always used ray
tracing to shade other objects inside or behind the
volume. This meant that said objects would look
aliased, unless you used Full OSA on the volume
(which is slow!). As well as this, it meant that you didn't
get a good alpha channel out of the volume to use for
compositing, similar to ray refracting materials.
This commit enables z transparency for volume
materials. Although it can be potentially less
physically correct, in most situations there's no
difference, and you get the benefit of nice sampling for
other objects and an alpha channel for compositing too.
Delegates now receive a TexParams* instead of float *coords. This gives texture nodes access to dxt, dyt, cfra as well as coords. This fixes the time node and allows nice sampling to be implemented.
* Add RenderResult.load_from_file to load whole multilayer exr's at once.
* Removed x/y offset from RenderLayer.load_from_file, better to encourage
using offset in begin_result() to minimize memory usage.
* Added WITH_OPENEXR in some screen/file/image module for scons/make, exr
was not working in some places there.
* data reorganisation - uses own values now instead of reusing surface material properties (i.e. an individual density value, rather than reusing alpha) Files saved with the old system won't load up the same after this.
* improved defaults and ui
* Transparency is now it's own panel, with a boolean toggle
+ enum for z/ray transparency (following mockup made by
William). Also had to change DNA flags for this.
* Disabled radiosity a bit more in render engine, it still had
some effects like auto autosmooth.
* Make some sliders in material buttons percentages in RNA.
* Some other small tweaks in layout and naming.
This bug fix makes the "non-smoothed" faces appear again (just like they do in 2.49 and blender2.5)
Meaning the "detect neighbour faces" isn't working 100%.
Integration is still very rough around the edges and WIP, but it works, and can render smoke (using new Smoke format in Voxel Data texture) --> http://vimeo.com/6030983
More to come, but this makes things much easier to work on for me :)
- Correct fix for file loading crash introduced by earlier point cache commit.
- Simulations are no longer calculated to current frame at render time automatically.
* This has to be thought through more carefully at some point, perhaps through render profiles.
* All simulations can be updated manually to current frame from any cache panel with the "update all to current frame" button.
- Some explanatory comments added for BKE_pointcache.h.
if theres very few faces its not worth it to create a separated tree for beinng reused.
should speedup some particle renders.
This "fixes" a bug relationed with a arithmetic precision on instances and raytrace of very close objects
which usually happens on rendering (almost) overlapping alpha-enabled leafs/feathers
