MultiTexturing
December 20, 2003 02:57 AM
Is it possible to blend two texture together on a polygon in opengl. Or do i have to manually edit the texture data, apply the new texture data with the old one and bnd that, then use that texture?

either use the multitexturing extention (see nehe''s tutorials) or render the object with 2 passes...
- Render as normal
- Turn on blending and turn off depthbuffer
- Render with the 2nd texture
- Turn off blending and turn on depthbuffer
Multitexturing is faster, but its a pain to implement. I personally dont like programming extentions

Use multitextureing extension.
Mostly all cards support it!

since ogl1.2 or so multitexturing isn't even an extension anymore. It now belongs to core opengl

Im new to extensions, but if a extension is part of the core OpenGL, do i still have to use the ARB version if im on windows?
Or can i use the non-ARB version?

Windows only has GL version 1.1, so you will still have to use the extension..
