Hi there, I am currently in the process of trying to clean up my shaders.
For the rendering my mesh I currently have a shader that can render phong lighting with a colour texture, shadow and wireframe (using nvidia method and geometry shader). I can get to a point based on what feature I want to use I can set a subroutine on the line:
shadeWithColor
shadwWithColorAndWire
shadeWithShadow
…
etc etc, basically function that render with the different features I want. That lead me to have some uniform or sampler that might be unused based on the subrutine I have selected, is that going to be a problem performance wise? I probably wont set those uniform because I know what subroutine I am going to use.
Any thought on the matter?
Or is this the wrong approach altogether?
