Exploring Student Difficulties in Ray Tracing through Drawing-Based Tasks
DescriptionRay tracing is a fundamental topic in introductory computer graphics courses. Previous research suggested that students find ray tracing particularly challenging. Ray tracing requires spatial understanding, mathematical skills, and programming skills, and it makes use of other computer graphics concepts such as illumination models. To investigate students’ conceptual understanding and identify common misconceptions, we conducted a drawing-based user study with 23 participants enrolled in an introductory course. Our findings revealed that the most common errors included misunderstandings of geometric and ray tracing concepts, as well as process-related mistakes. Based on our analysis, we propose an integrated instructional approach that incorporates spatial reasoning training, AR/VR-based visualization, and drawing-based assessment to reduce cognitive load and improve students’ understanding of ray tracing concepts.
