Real Time Visibility Culling With Hardware Occlusion Queries And Uniform Grids, Ilya Iseletsk Seletsky
Real Time Visibility Culling With Hardware Occlusion Queries And Uniform Grids, Ilya Iseletsk Seletsky
Master's Theses
Culling out non-visible portions of 3D scenes is important for rendering large complex worlds at an interactive frame rate. Past 3D engines used static prebaked visibility data which was generated using complex algorithms. Hardware Occlusion Queries are a modern feature that allows engines to determine if objects are invisible on the fly. This allows for fully dynamic destructible and editable environments as opposed to static prebaked environments of the past. This paper presents an algorithm that uses Hardware Occlusion Queries to cull fully dynamic scenes in real-time. This algorithm is relatively simple in comparison to other real-time occlusion culling techniques, …
Teaching Algebra Through Functional Programming:An Analysis Of The Bootstrap Curriculum, Robert Lee
Teaching Algebra Through Functional Programming:An Analysis Of The Bootstrap Curriculum, Robert Lee
Theses and Dissertations
Bootstrap is a computer-programming curriculum that teaches students to program video games using Racket, a functional programming language based on algebraic syntax. This study investigated the relationship between learning to program video games from a Bootstrap course and the resulting effect on students' understanding of algebra. Courses in three different schools, lasting about six weeks each, were studied. Control and treatment groups were given a pre and post algebra assessment. A qualitative component consisting of observations and interviews was also used to further triangulate findings. Statistical analysis revealed that students who completed the Bootstrap course gained a significantly better understanding …
