Hello. I created a cubemapshader with skybox textures as explained by TioPepe here:
Now I would like to change the textures of the shader by using the images of a webcam. I've already tried to recreate the cubemapshader frame by frame with beginPGL() ..... endPGL(), but the time for the calculations is too long, so that's the wrong way. Does anybody know how a fast method to change the shadertextures?
