Abstract
An application called Virtual Ray Tracer was developed to visualize the ray tracing process. Its goal is to help students of the computer graphics bachelor course at the Rijksuniversiteit Groningen, or anyone else interested, learn about this rendering technique. In this thesis, we expand the Virtual Ray Tracer by adding support for ray casting. Ray casting is an important technique in computer graphics visualisation. We present its principles to the user by drawing the volume as a transparent grid. Through this grid, we illustrate the rays and the samples that they take. Components such as the transfer function and compositing methods are visible and changeable. Our goal is to help students of the masters’ course Scientific Visualization at the Rijksuniversiteit Groningen gain a more detailed understanding of volume ray casting. We did a user study to evaluate how much the application helped users understand ray casting. Overall these results were positive with many users saying that they learned more about ray casting from the application.
