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...

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.

CG&A's Departments

Gabriel Taubin has graciously invited me to write this issue’s From the Editor column, giving me the opportunity to share my thoughts on what CG&A’s departments are, how they’re run, and why we hope you benefi t from them. In 2002, Jim Thomas, CG&A’s editor in chief at the time, asked me to serve as the associate editor in chief for departments. At the time, I wondered what I was getting myself...

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...
