Float texture

What’s the analogous of GL_TEXTURE_RECTANGLE_NV on Ati cards?
on nvidia cards i buil empty texture in this way:


On Ati cards?
Thank you

there is an extension called WGL_ATI_render_texture_rectangle. Unfortunately there´s no information anywhere on how to use it :frowning:

(HUMUS, please enlight us!)

There is ARB_texture_rectangle…

But I don’t think it is neccesary for using float textures on ATI hardware. AFAIK this limitation only originates from GFFX-class hardware, on ATI and GF6800 you can use float textures on any target…

GL_TEXTURE_RECTANGLE_EXT, it carries the same enumeration than the ARB counter part.
I tried using it on my work machine but it doesn’t seem to work quite well :frowning:

on ati hw simply use GL_TEXTURE_2D or whatever target u need :slight_smile:

Yes, that’s recommended. We support ARB_texture_rectangle as well, but it’s better to use the GL2.0 interface.
