Improving Shadow Map Filtering with Statistical Analysis
(The Eurographics Association, 2011)
Shadow maps are widely used in real-time applications. Shadow maps cannot be filtered linearly as regular textures, thus undersampling leads to severe aliasing. This problem has been attacked by methods that transform the ...
Crystal Scattering Simulation for PET on the GPU
(The Eurographics Association, 2011)
This paper presents a fast algorithm to simulate inter-crystal scattering to increase the accuracy of Positron Emission Tomography (PET). Theoretically, inter-crystal scattering computation would require the solution of a ...
