video texture maps
I am mapping videotextures to opengl objects for a video compositing app. I need to use clips that are 720x486 in resolution but opengl only lets me do 512x512 or 1024x1024
I can load a 720x486 image and scale it to 512x512 and then map it to a apect corrected palne but I loose reolution...
How can I get around this?
Re: video texture maps
You can use textures of dimension 2^m x 2^n (must be a power of 2). The best thing to do is use a dimension closest to your image size. When specifying the texture coordinates, just crop to the image.
