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
The main contribution of this commit is the possibility to save Freestyle configuration information inside .blend files. It required an extensive refactoring of the previous interface code.
The code has been tested and does not crash on my machine. If you encounter issues, please let me know (and if possible, sending me an sample .blend file).
DETAILS:
- refactored code to notify Freestyle when adding/removing render layers (FRS_freestyle_config.{h,cpp})
- corrected the freeing of style modules when files are read from / written to disk
- moved Freestyle configuration information into scene renderlayers, to allow loading / saving .blend files (DNA_scene_types.h DNA_freestyle_types.h FRS_freestyle.cpp)
- inserted temporary trick to prevent crashes when orthographic camera is used (SilhouetteGeomEngine.cpp), but outputting incorrect feature line calculations
