Point to grow and shrink by using gl_PointSize

Question

I\'m Trying to grow and shrink an point by using this function glPointSize()

    float i;
    for (i = 0.0; i < 400.0; i ++) {
        glPointSi         


        

Answer 1

Implementations have a limitation on the size of points. The GL_POINT_SIZE_RANGE can be used to fetch this limit, but it will generally be rather less than 400. A larger point size will be clamped to this range.
