Question
Is there a way to compute something in a first shader program (eg. screen-space coordinates from word-space ones) and access those results in an another shader program?
Possible solutions
- Give up multiple-shader-programs architecture and create one combined shader program
- Save somehow results to a buffer objects (I couldn't find out if this is possible except computation shaders)
- Render to texture and read the texture
Is there a nicer solution?
