0-4 Order of Spherical Harmonics

Spherical Harmonics is widely used in Computer Graphics. They are analogue to Fourier basis on a sphere, consists of a set of orthogonal functions to represent functions defined on the surface of a sphere. However, they are very tricky to implement due to lots of constants and integral functions. Here is a real-time visualization that…


Yet another shader for image fade-In effect

Taken iq’s background transparent code and Dr. Neyret’s advice: This shader can be used for rendering pop-up images in a 3D environment.
