Summary

0001038: Add a texture adaptor mechanism to allow using float textures as color and color textures as float

Description

I think it would be a big benefit to the artistic use of Lux if all the textures can be used in either format.

Additional Information

As discussed on IRC "<LordCrc> in GetFloatTexture, if the lookup fails we see if we have a color texture by that name, and if so create a new adapter texture on the fly"

Notes
(0003112) jeanphi (administrator) 2011-07-19 09:54	Textures already have an EvalFloat member which can be used on a color texture to get a float value. If Texture was derived from a BaseTexture class containing all but the Evaluate Texture member, we wouldn't even need an adaptor there because the GetFloatTexture could return a BaseTexture instead of a Texture<float> and we could use EvalFloat instead of Eval. Having float textures work with colors will require the creation of a mix texture on the fly, but that might be handled by appropriate CreateTexture members.
