I post-process (rendering to textures) and I finally render to the screen via a plane and an ortho camera.
I need to find the color of the pixel under the mouse, so I used the raycaster, assigned the plane and I got the UV coordinates under the mouse, so I’m one step before getting the actual pixel data, but surprisingly, raycaster doesn’t seem to have any pixel reading method at all.
Or should I access the renderer pixels via the WebGLRenderer’s canvas? If so, how?
I’m looking for an efficient method.
