Webgl_PointCoord is a fragment language input variable that contains the two-dimensional coordinates indicating where within a point primitive the current fragment is located. If … There is only one kind of point primitive: GL_POINTS. This will cause OpenGL to interpret each individual vertex in the stream as a point.
