2012-11-29	Fix #32900: object motion blur not working on the GPU. To make this work I ↵	Brecht Van Lommel
	disabled motion blurring of scale animation, probably not a big loss in practice since it's not so common to animate this, can be added back later.
2012-11-21	Fix #33256: cycles Z pass for orthographic camera was not right, now is more	Brecht Van Lommel
	useful for e.g. fog in compositing.
2012-10-18	Attempts to fix CUDA issues on sm 2.0 cards, still no luck getting motion blur	Brecht Van Lommel
	working, but this should make it not crash. Also fix for wrong shutter time, should have been shorter.
2012-10-09	Cycles: camera motion blur enabled.	Brecht Van Lommel
	Still more work needed to get object motion blur ready.
2012-09-17	Fix cycles panorama camera not working with depth of field, patch by	Brecht Van Lommel
	Daniel M. Basso, thanks!
2012-05-07	Fix most of #31307: cycles panorama camera not working correct with speed	Brecht Van Lommel
	vectors and window texture coordinates. Only for Fisheye Equisolid it's still not working correct yet. Patch from Dalai with modifications.
2012-05-05	Cycles: minor refactoring of fisheye code to fit code style.	Brecht Van Lommel

2012-05-04	Fisheye Camera for Cycles	Dalai Felinto
	For sample images see: http://www.dalaifelinto.com/?p=399 (equisolid) http://www.dalaifelinto.com/?p=389 (equidistant) The 'use_panorama' option is now part of a new Camera type: 'Panorama'. Created two other panorama cameras: - Equisolid: most of lens in the market simulate this lens - e.g. Nikon, Canon, ...) this works as a real lens up to an extent. The final result takes the sensor dimensions into account also. .:. to simulate a Nikon DX2S with a 10.5mm lens do: sensor: 23.7 x 15.7 fisheye lens: 10.5 fisheye fov: 180 render dimensions: 4288 x 2848 - Equidistant: this is not a real lens model. Although the old equidistant lens simulate this lens. The result is always as a circular fisheye that takes the whole sensor (in other words, it doesn't take the sensor into consideration). This is perfect for fulldomes ;) For the UI we have 10 to 360 as soft values and 10 to 3600 as hard values (because we can). Reference material: http://www.hdrlabs.com/tutorials/downloads_files/HDRI%20for%20CGI.pdf http://www.bobatkins.com/photography/technical/field_of_view.html Note, this is not a real simulation of the light path through the lens. The ideal solution would be this: https://graphics.stanford.edu/wikis/cs348b-11/Assignment3 http://www.graphics.stanford.edu/papers/camera/ Thanks Brecht for the fix, suggestions and code review. Kudos for the dome community for keeping me stimulated on the topic since 2009 ;) Patch partly implemented during lab time at VisGraf, IMPA - Rio de Janeiro.
2012-05-02	Fix #31168: cycles mask layer should only affect objects for camera rays.	Brecht Van Lommel
	Fix: texture coordinate normal output was not correct, still changed under object transform.
2012-04-30	Cycles: support for motion vector and UV passes.	Brecht Van Lommel
	Most of the changes are related to adding support for motion data throughout the code. There's some code for actual camera/object motion blur raytracing but it's unfinished (it badly slows down the raytracing kernel even when the option is turned off), so that code it disabled still. Motion vector export from Blender tries to avoid computing derived meshes when the mesh does not have a deforming modifier, and it also won't store motion vectors for every vertex if only the object or camera is moving.
2012-04-30	Cycles: remove a few usages of double, to fix opencl warnings.	Brecht Van Lommel

2012-04-16	Fix #30966: cycles nan mesh vertices got set to (0, 0, 0), now remove them ↵	Brecht Van Lommel
	instead.
2012-03-20	Fix #30603: cycles incorrect ray differentials when rendering with panorama	Brecht Van Lommel
	camera, causing bump map issues.
2012-02-28	Cycles: support for camera rendering an environment map with equirectangular	Brecht Van Lommel
	environment map, by enabling the Panorama option in the camera. http://wiki.blender.org/index.php/Doc:2.6/Manual/Render/Cycles/Camera#Panorama The focal length or sensor settings are not used, the UI can be tweaked still to communicate this, also panorama should probably become a proper camera type like perspective or ortho.
2011-12-20	Cycles: avoid using float3 in kernel constant memory, just so we're sure ↵	Brecht Van Lommel
	alignment is working compatible between cpu and gpu.
2011-11-22	Cycles: OpenCL tweaks	Brecht Van Lommel
	* Reduce kernel arguments size, helps compile for apple nvidia. * Fix use of unitialized variable in displace kernel. * Use build flags in opencl kernel md5 hash. * Reorganize code for kernel feature #defines a bit.
2011-09-16	Cycles: tweaks to properties and nodes	Brecht Van Lommel
	* Passes renamed to samples * Camera lens radius renamed to aperature size/blades/rotation * Glass and fresnel nodes input is now index of refraction * Glossy and velvet fresnel socket removed * Mix/add closure node renamed to mix/add shader node * Blend weight node added for shader mixing weights There is some version patching code for reading existing files, but it's not perfect, so shaders may work a bit different.
2011-04-27	Cycles render engine, initial commit. This is the engine itself, blender ↵	Ton Roosendaal
	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: http://www.cs.columbia.edu/CAVE/software/softlib/dorf.php
