81b371a451 Cycles Hair UI: 
* Code cleanup, removed some unneeded code
* Moved "Cycles Hair Rendering" panel above "Cycles Hair settings"
* "Cycles Hair settings" panel is only visible when hair rendering ("use_curves") is enabled.

e9ba345c46 New feature 
Patch [#33445] - Experimental Cycles Hair Rendering (CPU only)

This patch allows hair data to be exported to cycles and introduces a new line segment primitive to render with.

The UI appears under the particle tab and there is a new hair info node available.

It is only available under the experimental feature set and for cpu rendering.

779662aff7 Fix #33641: cycles self intersection artifacts with motion blur and one of the 
X/Y/Z coordinates close to 0.

80d22a3f12 Cycles OSL: handle new getattribute constant folding with renderstate NULL check, 
and fix #33654, distance to line segment function is not implemented but compiled
anyway, now it should give a compile error.

e5b457dbc9 Cycles: merge some changes from a local branch to bring network rendering a bit 
more up to date, still nowhere near working though, but might as well commit this
in case someone else is interested in working on it.

motion vector pass is not enabled.

54729df020 Cycles OSL: diffuse_toon and specular_toon closures. These are toon shaders with 
a size parameter between 0.0 and 1.0 that gives a angle of reflection between
0° and 90°, and a smooth parameter that gives and angle over which a smooth
transition from full to no reflection happens.

These work with global illumination and do importance sampling of the area within
the angle. Note that unlike most other BSDF's these are not energy conserving in
general, in particular if their weight is 1.0 and size > 2/3 (or 60°) they will
add more energy in each bounce.

ab2c273b12 Added GPL header to sconscripts! 
Also changed shebang to '#!/usr/bin/env python', this is more portable across unixes...

a0855a95db Cycles: add "Textures" panel in particle properties, to make it possble to add 
textures when Cycles is selected as render engine.

176292067e Cycles OSL: small optimization to geometry node, tangent output still was 
not properly optimized out in some cases.

For reference, setting this will give detailed information about OSL shaders:
export OSL_OPTIONS="statistics:level=1,debug=1,llvm_debug=1"

06888b7beb Cycles OSL minor optimizations: recycle shading context, don't do memory 
allocations for trace data, avoid some virtual function calls. Only helps
a few percentages.

0f5b5bb5f1 Cycles: make "Open Shading Language" a boolean toggle, the other option "GPU Compatible" was confusing. 2012-12-14 15:26:49 +00:00

error in some builds.

5616c7a058 Cycles: disable scaling up of ray differentials after diffuse/glossy bounce, this 
isn't working well for OSL texture filtering and wasn't very helpful to begin
with, a better solution should be possible.

3945979f2b Fix #33486: cycles CPU image textures were offset wrong by half a pixel compared 
to OpenGL/CUDA/OSL rendering.

3759c10e5c Fix #33485: cycles OSL now autodetects the presence of emission and transparent 
closures to enable multiple importance sampling and transparent shadows.

188718a3d5 OSL Shader Files: 
* Simplify default color values, where each component was the same.
* Initialize closures as Null Closure, rather than assigning an existing closure, gets overwritten anyways.

43c04eefe3 Cycles: RGB and Vector Curves nodes now supported, with the limitation that the

7c81952179 Cycles: trick to make building with OSL trunk work as well, it has a different 
name for LoadMemoryShader so we make it call the right name depending on which
is available.

369b9fcf0f Fix missing mapping and influence panel for particles when cycles is selected 
as render engine. Still missing is colors and texture slots, but that's too
tricky to fix this close to release.

38dcce2da2 FIX: OSL mix shader clamps 2nd color component to 3rd one. 
Previously the OSL Mix shader node was clamping the 2nd color component (green) to the 3rd color component (blue). Now every component is clamped on its own.

a9d889cba4 Fix #33405: preview render getting stuck in a particular .blend file, ObjectKey 
operator< had wrong brackets, changed it now to be more clear.

Fix #33404: crash GPU rendering with OSL option still enabled. There was a check
to disable OSL in this case, but it shouldn't have modified scene->params because
this is used for comparison in scene->modified().

41f98978e3 Fix cycles issue when NaN is used for RGB ramp, can access array out of bounds then. 
OSL noise() function is generating NaN's in certain cases, fix for that goes to our
OSL branch.

Also add missing minimum weight and max closure checks to OSL, forgot to add these
when fixing another bug.

of via thread local storage, and creating ustrings for attribute lookup.
