For the visualization of volume data the application of transfer functions is used widely. In this area the pre-integration technique allows high quality visualizations and the application of arbitrary transfer functions. For regular grids, this ...

To create realistic images using computer graphics, an important element to consider is atmospheric scattering, that is, the phenomenon by which light is scattered by small particles in the air. This effect is the cause of the light beams produced by ...

Texture mapping is a core technology of current real-time 3D graphics systems. To avoid aliasing artifacts, the texture mapping resample process requires proper filtering. We present a new resample algorithm for two-pass forward texture mapping that is ...

We introduce several new variants of hardware-based adaptive texture maps and present applications in two, three, and four dimensions. In particular, we discuss representations of images and volumes with locally adaptive resolution, lossless compression ...
