Texture from Another Texture

Is it possible to create a new texture using information stored in another texture?

Can I specify texture coordinates in the new texture and texture coordinates in an existing texture such that the new texture is a warped/distorted version of the existing texture?

I hope that makes sense. Thanks.

Yes it is possible to warp textures. There are many ways of doing it. You need to be more specific here…

With render to texture you can do more or less everything.

However, statically linking one image into another using texture-coordinates, is impossible (if you know what I mean, and if that is what you meant).

It’s pretty simple: Everything that you can get on screen, you can then store in a new texture.
