1. 1. Real-Time Shading and Accurate Shadows Using GPGPU Techniques

   Författare :Ola Olsson; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; virtual shadow-maps; real time; transparency; shading; shadows; rendering; shadow volumes; GPGPU; GPU;

   Sammanfattning : Over the last 10-15 years, computer graphics hardware has evolved at a tremendous pace, with an exponential growth in the number of transistors. This evolution has transformed the Graphics Processing Unit (GPU) from an entirely fixed-function unit into a highly parallel general-purpose architecture that can be programmed using high-level programming languages.

3. 2. Efficient real-time visibility testing

   Författare :Erik Sintorn; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; soft shadows; volumetric shadows; deep shadow-maps; order-independent transparency; hair; shadows; rendering; visibility;

   Sammanfattning : Visibility testing is an integral part of many computer graphics algorithms. For example, algorithms that generate images with shadows, ambient occlusion, environment lighting or transparency all require an efficient means of establishing the visibility between two or more points in a virtual scene.
