Abstract

Ray tracing is a fundamental technique in computer graphics, used to generate realistic images by simulating the behavior of light as it interacts with objects in a scene. The Virtual Ray Tracer (VRT) was developed as an educational tool to provide users with an interactive environment for understanding ray tracing concepts. While VRT has successfully visualized surface-based ray tracing, recent efforts have expanded its capabilities to include volume ray casting, a technique used for rendering the internal structures of volumetric data. This thesis extends the functionality of VRT by improving the visualization of volume ray casting. A new accelerated ray casting pipeline was implemented to allow users to interact with and visualize voxel-based datasets in real time. Key enhancements include real-time visualization of the voxel grid and the ability to dynamically adjust settings such as sampling distance, transfer functions, and compositing methods. Through this work, VRT now supports an interactive and intuitive exploration of volume rendering concepts, with a focus on educational effectiveness and usability. The results of this project contribute to a deeper understanding of ray casting for both novice and advanced users, making VRT a more powerful tool for learning computer graphics principles.
