Spherical Harmonics Playground

This is a simple application that loads an OBJ file and an environment map and calculates & displays the corresponding 3rd order spherical harmonics coefficients for it. The coefficients can also be modified at runtime to see the effect of each coefficient.

Here is a dog statue (that I attempted to scan a few years ago) in a room environment: dog statue in room environment

And here is a simple sphere in an outdoor environment: sphere in outdoor environment
