Yes, it's easy: Just render as many vertices as you have pixels, but don't bind a vertex buffer. Instead, compute the pixel corresponding to the current vertex by obtaining the vertex ID ( gl_VertexID) (you should render as points.) From the vertex ID, you can issue a fetch on the texture and get the data (make sure you use texelFetch .) Share.
