Raytracing has long been known to offer higher
fidelity and photo
realism for image generation as compared with
traditional raster graphics techniques, particularly in the modeling of multiple
reflections and refractive

However, raytracing’s

computationally intensive nature and traditionally CPU
bound architecture precluded
it as a solution for real
time applications for all but massively
parallel distributed processing architectures or

certainly not for low
cost PC

ent advancements in GPU technology, however, such as
nVidia’s Optix engine and supporting hardware, have made raytracing increasingly viable for these applications,
with the potential to accurately and quickly predict important sensor
band phenomena such a
s volumetric scattering,
thermal interactions among scene elements, and coherent interference.

In this presentation, JRM discusses its recent
work toward a comprehensive approach for real
time physics
based GPU raytracing, particularly as it applies to
spectral signature simulation in the EO, IR and RF sensor domains.
