2014-12-25Cleanup: Fix Cycles Apache header.Thomas Dinges
This was already mixed a bit, but the dot belongs there.
2014-10-31Fix T42391: HSV correction shader node gives negative valuesSergey Sharybin
This mainly happens when over-saturating already saturated color. After some discussion with Campbell and loads of tests we decided to clamp the result RGB color. As an alternative we might want to clamp corrected HSV values instead, but that would lead to some larger changes in the render results. TODO: The same is to be done for compositor nodes.
2013-11-18Cycles: change __device and similar qualifiers to ccl_device in kernel code.Brecht Van Lommel
This to avoids build conflicts with libc++ on FreeBSD, these __ prefixed values are reserved for compilers. I apologize to anyone who has patches or branches and has to go through the pain of merging this change, it may be easiest to do these same replacements in your code and then apply/merge the patch. Ref T37477.

2013-06-11Cycles / Wavelength to RGB node:Thomas Dinges
* Added a node to convert wavelength (in nanometers, from 380nm to 780nm) to RGB values. This can be useful to match real world colors easier. * Code cleanup: ** Moved color functions (xyz and hsv) into dedicated utility files. ** Remove svm_lerp(), use interp() instead. Documentation: http://wiki.blender.org/index.php/Doc:2.6/Manual/Render/Cycles/Nodes/More#Wavelength Example render: http://www.pasteall.org/pic/show.php?id=53202 This is part of my GSoC 2013. (revisions 57322, 57326, 57335 and 57367 from soc-2013-dingto).

conversion.
2012-11-23Fix #33267: cycles math node power gave different results for CPU and GPU. TheBrecht Van Lommel
GPU variants do not support pow(-1, 2), it doesn't check for even exponents, do manually now.

2011-12-29bugfix: [#29711] Cycles - HSV Node - Hue Change BugDalai Felinto
* Adding hue instead of removing it. fmod doesn't work as % when it comes to negative numbers: fmod( 1.3, 1) == 1.3 % 1 == 0.3 fmod(-0.3, 1) != -0.3 % 1
2011-12-02HSV Color Node for CyclesDalai Felinto
......................... note, the OSL code has a problem. In the original node the input and output nodes have the same name (Color). So this will be fixed here once Brecht come up with a nice autorenaming (or we do a doversion patch) for that.
