Red pixels aren’t re-computed because they are stored in an auxiliar buffer to be reprojected. When camera moves slowly or it’s stopped the FPS reaches to infinite and beyond… :p

Drawing circle primitives using GL_POINTS in GLSL

One of the best things that I love in openGL due to performance is to draw using GL_POINTS instead standard triangles or lines, because it’s an ideal primitive for debug purposes or 3d geometry editor (I think that it’s more easy than GL_POINT_SPRITES to show all vertices in our geometry,…
