Texture Mapping with Vector Graphics: A Nested Mipmapping Solution
Texture mapping with vector graphics, rather than raster graphics generates better rendering quality. This paper discusses a fully developed approach of texture mapping 3D objects...

Orientable textures for image-based pen-and-ink illustration
We present an interactive system for creating pen-and-ink-style line drawings from greyscale images in which the strokes of the rendered illustration follow the features of the or...

Real-Time, Accurate Depth of Field using Anisotropic Diffusion and Programmable Graphics Cards
Computer graphics cameras lack the finite Depth of Field (DOF) present in real world ones. This results in all objects being rendered sharp regardless of their depth, reducing the...
