View Full Version : OpenGL and 3D Look-Up Tables

03-11-2003, 12:59 AM
hi all,

is it possible to apply a 3DLUT (3D Look Up Table) on the pixel bufffer of a graphic adapter ? Is it doable using OpenGL ?
How could I achieve that mechanism ?
I have to use 3DLUTs in order to emulate different Monitors.
Basically, suppose an image is displayed using glDrawPixel() or textures quads, how to apply a 3D Look Up Table using OpenGL API and graphic cards properties ?

Depends on the target HW.. TextureLookups and a 3dtexture will certainly work, but only on cards that supports it.
