Did some bad spacing in recent commits, better to get rid of those so
they does not confuse those who're working on sources.

Originally we thought it's needed in order to distinguish builtin file from
filename which starts with '@', but the filepath is actually full path there
and it's unlikely to have file system where '@' is a proper root character.
Surprisingly this does not give visible speed differences, but it's still
nice to get rid of redundant check.

This inconsistency drove me totally crazy, it's really confusing
when it's inconsistent especially when you work on both Cycles and
Blender sides.
Shouldn;t cause merge PITA, it's whitespace changes only, Git should
be able to merge it nicely.

This is a bit of a mess because of the header dependency hell, but
since the tweak is small enough it's gonna be fine.

This was already mixed a bit, but the dot belongs there.

Even tho it's not 100% clear when we'll switch to OSL-1.6 we'd better
start preparing earlier for this, so we don't spend time on this later.
Plus this code helps troubleshooting some OSL issues, which requires
testing with latest versions of OSL.

This means packed images and movies are now supported when using OSL
backend for material shading.
Uses special file name to distinguish whether image is builtin or not.
This part might become a bit smarted or optimized a bit, but it's good
enough with this implementation already.

it's possible that runtime optimizer would call get_attribute
with NULL renderstate. As per documentation, it's valid to
return false in that cases and in worst case we'll just miss
some possible optimization.
Supporting such cases would require some bigger changes to
Cycles since attributes are only set to up for the kernel
after shader compilation.
Thanks Brecht for review!

Gives overall ~3% speedup in own tests for BMW scene.

This can for example be useful if you want to manually terminate the path at
some point and use a color other than black.

These are internally stored as a 3D image textures, but accessible like e.g.
UV coordinates though the attribute node and getattribute().
This is convenient for rendering e.g. smoke objects where data like density is
really a property of the mesh, and it avoids having to specify the smoke object
in a texture node, instead the material will work with any smoke domain.

This does not support staying fixed while the surface deforms, but for static
meshes it should match up with the surface texture coordinates. Implemented
as a matrix transform from objects space to mesh texture space.
Making this work for deforming surfaces would be quite complicated, you might
need something like harmonic coordinates as used in the mesh deform modifier,
probably will not be possible anytime soon.

This code can't actually be enabled for building and is incomplete, but it's
here because we know we want to support this at some point and there's not much
reason to have it in a separate branch if a simple #ifdef can disable it.

for texture system in advance. Patch by Martijn Berger, with some tweaks.
There was about a 10% performance improvement on OS X in my tests with the
images.blend test file. This may be less on other platforms because OS X has
particularly slow mutex locks.

* Added a Ray Depth output to the Light Path node, which gives the user access to the current bounce.
This can be used to limit the maximum ray bounce on a per shader basis. Another use case is to restrict light influence with this, to have a lamp only contribute to the direct lighting.

This is part of my GSoC 2013 project. SVN merge of r58091 and r58772 from soc-2013-dingto.

It seems there's something in OSL/LLVM that's not thread safe, but I couldn't
figure out what exactly. Now all renders share the same OSL ShadingSystem which
should avoid the problem.

* Added missing define into SConscript file. This also makes r54232 obsolete, so removing this again.

big lamps and sharp glossy reflections. This was already supported for mesh
lights and the background, so lamps should do it too.
This is not for free and it's a bit slower than I hoped even though there is
no extra BVH ray intersection. I'll try to optimize it more later.
* Area lights look a bit different now, they had the wrong shape before.
* Also fixes a sampling issue in the non-progressive integrator.
* Only enabled for the CPU, will test on the GPU later.
* An option to disable this will be added for situations where it does not help.

number of keys in the curve, rather than curve segments with the indices of two
keys. ShaderData.segment now stores the segment number in the curve.

should be no functional changes yet. UV, tangent and intercept are now stored
as attributes, with the intention to add more like multiple uv's, vertex
colors, generated coordinates and motion vectors later.
Things got a bit messy due to having both triangle and curve data in the same
mesh data structure, which also gives us two sets of attributes. This will get
cleaned up when we split the mesh class.

* Implemented the Hair Info Node for OSL.

check,
and fix #33654, distance to line segment function is not implemented but compiled
anyway, now it should give a compile error.
|

allocations for trace data, avoid some virtual function calls. Only helps
a few percentages.
