Abstract

Currently, high quality physically based rendering is one of the main challenges in computer graphics, due to its computational intensity and complexity. This process has been taking advantage of the massive parallel calculations allowed by the GPU’s, leading Nvidia to develop a Ray Tracing API, called Optix, which performs intersection calculations of line segments with three-dimensional geometry on the GPU.

The three-dimensional content creation software, such as Autodesk Maya, provides physically based rendering processes typically used in the production of high quality or photo-realistic images. However, most of these processes are executed in CPU, and the production of a single image can take several hours. These rendering processes based on optical physics are currently converging to the use
of GPU’s, which allows greater speed in production of images.

The aim of this thesis is to develop an interactive renderer of high quality images, integrate it with a three-dimensional content creation software and evaluate the results. This process is intended to allow the display of high quality three-dimensional content at interactive frame rates, allow light manipulation, objects materials and camera transformations.

The results show that currently physically based rendering processes running on the GPU allow the production of high quality images at interactive frame rates.
