Abstract
Techniques are disclosed to determine the irradiance from a disk light source with much higher accuracy than may be obtained using the common approximation often used currently. By pre-computing, SH coefficients using a specific coordinate frame, only six SH coefficients need to be stored in a first and second texture, one used to determine irradiance of a point within the radius of a disk light source and another for more distant points.
