Résumé: | Creating a virtual simulation of the world around us that looks and behaves properly has
always been the ultimate goal of old and modern graphic technologies that have long struggled
with how light works, an effectively infinite number of photons zip around, reflecting off
surfaces and passing through objects, all based on the molecular properties of each object.
Simulating infinity with a finite resource like a computer's computational power is a recipe
for disaster. Clever approximations were needed and new techniques were introduced.
This work describes the implementation of a GPU accelerated path tracer, it was organized in
the form of a case study, evaluating different techniques and their impact on the final product.
This report discusses complications typically encountered when implementing a path tracer
and how these can be bypassed. Considerations were taken concerning quality, rendering
speed, extensibility, configurability, and compatibility when features were chosen for
implementation. Light interaction with surfaces, diffuse reflections, physically accurate
shadows, reflections and refractions, geometric properties and much other real world effects
are introduced.
To compare the effectiveness of the implementation held under the GPU platform, we have
opted for implementing an equivalent algorithm and test it under a CPU platform. The final
scenes are presented at the end of this thesis. |
