WebAs you can see we used a pre-processor directive in GLSL to define the number of point lights we want to have in our scene. We then use this NR_POINT_LIGHTS constant to create an array of PointLight structs. … GL_POINT should be GL_POINTS in displaypoint. GL_POINT means something else entirely -- you still use GL_POINTS even if you only display one point; You were clearing each time you drew a point, so you would only ever see one point (but the point wasn't drawing in the first place due to the above). Only clear when you want to wipe the whole screen.
