2021-10-04	Fix T90815: wrong Cycles OSL normal map render after recent optimization	Brecht Van Lommel

2021-03-15	Fix T86121: Cycles Attribute returning wrong results with OSL	Brecht Van Lommel
	Fix uninitialized variable in the OSL shader.
2020-02-12	Cleanup: Fix build warnings from OSL shader compilation	Ray Molenkamp
	There were to copies of stdosl.h one from stock OSL and one in the cycles tree augmented with cycles specific closures. moved the cycles ones to stdcycles.h and copied the stock stdosl.h and accompanying headers from the OSL shader folder. for further details see D6812.

2018-07-26	Cycles: Add reflection fix to Bump and Normal Map nodes	Lukas Stockner
	While changing the shading normal is a great way to add additional detail to a model, there are some problems with it. One of them is that at grazing angles and/or strong changes to the normal, the reflected ray can end up pointing into the actual geometry, which results in a black spot. This patch helps avoid this by automatically reducing the strength of the bump/normal map if the reflected direction would end up too shallow or inside the geometry.

2016-08-30	Fix T49187: inconsistent Normal Map node output for backfacing polygons.	Alexander Gavrilov
	There basically are two issues here: in smooth mode (and all non-tangent normal map types) it doesn't invert the normal for backfacing polys; on the other hand for flat shaded tangent type it is inverted too soon. This fix does a brute force correction by checking the backfacing flag. Reviewers: #cycles, brecht Reviewed By: #cycles, brecht Differential Revision: https://developer.blender.org/D2181

2012-11-08	Cycles: add strength input for normal map node.	Brecht Van Lommel

2012-11-06	Cycles: 4 new nodes.	Brecht Van Lommel
	* Tangent: generate a tangent direction for anisotropic shading. Can be either radial around X/Y/Z axis, or from a UV map. The default tangent for the anisotropic BSDF and geometry node is now always radial Z, for UV tangent use this node now. http://wiki.blender.org/index.php/Doc:2.6/Manual/Render/Cycles/Nodes/More#Tangent * Normal Map: generate a perturbed normal from an RGB normal map image. This is usually chained with an Image Texture node in the color input, to specify the normal map image. For tangent space normal maps, the UV coordinates for the image must match, and the image texture should be set to Non-Color mode to give correct results. http://wiki.blender.org/index.php/Doc:2.6/Manual/Render/Cycles/Nodes/More#Normal_Map * Refraction BSDF: for best results this node should be considered as a building block and not be used on its own, but rather mixed with a glossy node using a fresnel type factor. Otherwise it will give quite dark results at the edges for glossy refraction. http://wiki.blender.org/index.php/Doc:2.6/Manual/Render/Cycles/Nodes/Shaders#Refraction * Ambient Occlusion: controls the amount of AO a surface receives, rather than having just a global factor in the world. Note that this outputs a shader and not a color, that's for another time. http://wiki.blender.org/index.php/Doc:2.6/Manual/Render/Cycles/Nodes/Shaders#Ambient_Occlusion
