billboards is random about a disk of radius r at a random height Y. Spherical coordinates can be coded as a complete sphere or half sphere by limiting φ...
spherical coordinates (radius (r), polar angle (θ) and azimuthal angle (ϕ)). This allows a simple transformation, M, to map the individual spherical coordinates...
Shows how the geometry of lightbeams going through a concave, spherical lens from left to right, points out the focal point and hence the focal length...
