| Summary | 0001942: Allow optical+physical material properties in addition to RGB color specification | ||||
| Description | Advanced spectral renderers (like LuxRender and to some extend Povray) do not use RGB internally, but physical spectral reflection, refraction, emission properties, given for example as color temperature, spectrum texture or look-up table[1], lamp-vendor-provided IES file[2], and physical refraction and reflection indices.[3] In addition to specify plain RGB color, shininess and translucency which were fine in the time of "classical" fixed-function OpenGL not using actual shaders and programmable shaders implementing the traditional Phong lighting model, it is desirable to specify physical optical properties, which are supported by LuxRender, Povray and other advanced rendering engines.

I support the request, makes sense and is used in common CAD systems. |
