+# Procedural textures
+
+## the idea
+We need a way to produce textures procedurally.
+These texture can be generated on the CPU or the
+GPU with a shader and the proper rendering target,
+and then sent back to main memory.
+
+## What textures?
+
+The procedure can be use to pre-calc env maps
+and lighting maps, or textures (fractals, fonts, etc.)
+
+## how
+
+This could be integrated in the asset system as
+a special "compression" case (instead of "NONE", you
+have "PROC(the_function_name_to_call)" as compression
+type).
+
+## code
+
+let's have a proper 'src/procedural' sub-directory
+with all the code related to procedural textures.
