| Spherical Harmonics |
The image at left is from An Open Inventor program which emits particles
according to
the spherical harmonics equations provided in Glassner's
Principles of Digital Image Synthesis pg 675. The
particles are emitted by randomly picking a theta and phi and
solving the equation. The value returned is compared against
a minimum value which can be changed interactively by use of
a dragger. The order, l and degree, m can also be modified
interactively using draggers. A Quicktime movie of the emitter
can be viewed here (543K).
All code used for this project can be viewed below, or
downloaded as a tar file here.
