Experiments in CG

Distance and absorption of the tails in the CG 30 / CG 31 / CG 38 complex ?

From a mosaic of rather deep V and I images of the CG 30/CG 31 region we report distances and absorptions of these and other interesting interstellar features, the distances and absorptions estimates are based on shifting a new (V−I) 0 – M V relation obtained from nearby, presumably unreddened Hipparcos stars with luminosity class V classification to fit confining trends in the (V−I) – V diagra...

Cg in Two Pages

The latest real-time graphics architectures include programmable floating-point vertex and fragment processors, with support for data-dependent control flow in the vertex processor. We present a programming language and a supporting system that are designed for programming these stream processors. The language follows the philosophy of C, in that it is a hardware-oriented, generalpurpose langua...

Piecewise Definable Cg Triviality and Definable Cg Compactification

Let G be a definably compact definable C group and 1 ≤ r < ∞. Let X be a definable CG submanifold of a representation of G and Y a definable C submanifold of R. We prove that every G invariant surjective submersive definable C map f : X → Y is piecewise definably CG trivial.

Real-time Shadows in CG

This work should give an overview of various shadow techniques used in real-time rendering. Proper shadows are a crucial part of realistic looking scenes and therefore a huge research field in computer graphics. We will focus on the two major shadowing techniques shadow volumes and shadow mapping, including most popular rendering approaches, whereby the most practical approaches should be point...
