b2142d6533 Cycles: OSL compile fixes. 2012-10-17 22:58:18 +00:00
Lukas Toenne
0551aa14bb Fix for OSL 'background' attributes (attributes that are not associated to a particular object). Atm this is only the 'ray_length' attribute. 
Background attributes are used as fallback in two cases:
1) Non-object light samples (e.g. lamp shaders)
2) Fallback if no implicit object attribute can be found

* Ray Length is now available in OSL (via get_attribute)

af537c283c Fix for (camera) motion blur changes in Cycles OSL. Compilation was broken due to changed object transform functions. Also added a few missing renderer service implementations for matrix callbacks. 2012-10-16 10:59:35 +00:00

c4de45e56b Implemented the Particle Info for OSL. Uses the following attributes: 
* std::particle_index
* std::particle_age
* std::particle_lifetime
* std::particle_location
* std::particle_size
* std::particle_velocity
* std::particle_angular_velocity

Just as with SVM the rotation state attribute is currently disabled due to lack of a proper quaternion or matrix type in Cycles nodes.

df79ab5a77 Added Object Info node implementation for OSL. This uses an additional attribute check in the osl_services callback for special attribute names related to objects: 
* std::object_location
* std::object_index
* std::material_index
* std::object_random

Other object-based attributes can be added for particle info in the same way.

748582f49e Cycles / OSL: 
Fixes for API changes in OSL RendererServices:

* Added two new required get_matrix methods, from OSL RendererServices (otherwise the constructor fails). The two new matrix methods probably still need an implementation. 
* Removed deprecated "get_pointcloud_attr_query" and "pointcloud". There are two new routines for pointclouds, function headers for those are there.

* Removed the (unused) PARTIO code parts from OSL. It was marked as not tested / not working, and due to the api changes here broken for sure. Code is still in svn history if needed.

da376e0237 Cycles render engine, initial commit. This is the engine itself, blender modifications and build instructions will follow later. 
Cycles uses code from some great open source projects, many thanks them:

* BVH building and traversal code from NVidia's "Understanding the Efficiency of Ray Traversal on GPUs":
http://code.google.com/p/understanding-the-efficiency-of-ray-traversal-on-gpus/
* Open Shading Language for a large part of the shading system:
http://code.google.com/p/openshadinglanguage/
* Blender for procedural textures and a few other nodes.
* Approximate Catmull Clark subdivision from NVidia Mesh tools:
http://code.google.com/p/nvidia-mesh-tools/
* Sobol direction vectors from:
http://web.maths.unsw.edu.au/~fkuo/sobol/
* Film response functions from:
