Direct Lighting Models for Ray Tracing with Cylindrical Lamps
Zimmerman Kurt, Indiana University Bloomington, Indiana. E-mail address: kuzimmer@cs.indiana.edu
Fluorescent lights are used for many lighting applications, such as classrooms and shopping centers, and neon lights are again becoming popular for advertising signs and cosmetic lighting. Fluorescent and neon luminaires 1 can be modeled as diffuse emitting cylinders with associated spectral distributions. The following gem presents a method for performing the direct lighting computations for cylindrical luminaires in distribution ray tracing.
This gem extends a previous entry (Wang 1992) that presents physically correct methods for computing the contribution of spherical and ...
