WebMar 28, 2009 · A perfect cylinder is two circles (the ends) separated by some distance with the middle space filled in. The best way to render one is to approximate the circles with triangles. Pick the number of slices of a circle you want to use (think slices of a pie), pick a radius, and pick a length of the cylinder. WebYou just decide how many vertices you want in the various directions (2 for a sphere and 1 for a cylinder) and generate them around the shape using sin() and cos(). You can do a Google search for the mathematical functions for spheres and cylinders. hugh jackman and ryan reynolds video
