1. 1. Real-Time Algorithms and Intersection Test Methods for Computer Graphics

   Författare :Tomas Möller; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; texture; ray tracing; radiosity; color; three-dimensional graphics and realism; virtual reality; algorithms; shadowing; shading;

   Sammanfattning : In real-time computer graphics applications, at least three major forces are in conflict, namely, rendering speed, the level of realism, and interactivity. Therefore this thesis focuses on real-time algorithms that enhance the realism while maintaining high rendering speed, and on fast intersection test methods in order to speed up, for example, collision detection, picking processes and ray tracing.

4. 3. A Real-Time Soft Shadow Volume Algorithm

   Författare :Ulf Assarsson; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; three-dimensional graphics and realism; shading; pixel shaders; graphics hardware; shadowing; soft shadows; computer graphics;

   Sammanfattning : Rendering of shadows is a very important ingredient in three-dimensional graphics since they increase the level of realism and provide cues to spatial relationships. Area or volumetric light sources give rise to so called soft shadows, i.e., there is a smooth transition from no shadow to full shadow. LÄS MER

5. 4. Adaptive Bounding Volume Hierarchies for Efficient Collision Queries

   Författare :Thomas Larsson; Björn Lisper; Tomas Akenine-Möller; Stefane Redon; Mälardalens högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Bounding volume hierarchies; Collision detection; Rigid bodies; Deformable models; Data structures; Simulation; Animation; Three-dimensional graphics and realism; Computer science; Datavetenskap; Datavetenskap;

   Sammanfattning : The need for efficient interference detection frequently arises in computer graphics, robotics, virtual prototyping, surgery simulation, computer games, and visualization. To prevent bodies passing directly through each other, the simulation system must be able to track touching or intersecting geometric primitives. LÄS MER
