Hierarchical depth culling is an important optimization, which is present in all modern high performance graphics processors. We present a novel culling algorithm based on a layered depth representation, with a per-sample mask indicating which layer ...

Euclidean-based distance metrics are commonly used for measuring geometric shape distortions of 3D models, but have several drawbacks. They have strict requirements regarding model representation and usually necessitate expensive surface sampling or ...

With large scientific and medical datasets, visualization tools have trouble maintaining a high enough frame-rate to remain interactive. In this paper, we present a novel GPU based system that permits visualization of isosurfaces in large data sets in ...

We propose a novel shadow texture generation method with linear processing time using a shadow depth buffer (SZ-Buffer). We also present a method that achieves further speedup using temporal coherence. If the transition between dynamic and static state ...

The problem of reassembling an object from its parts or fragments has never been addressed with a unified computational approach, which depends on the pure geometric form of the parts and not application-specific features. We propose a method for the ...

This article describes a semi-automatic system for the reconstruction of archaeological finds from their fragments. Virtual Archaeologist is a system that uses computer graphics to calculate a measure of complementary matching between scanned data and ...

Contemporary graphics architectures are based on a hardware-supported geometric pipeline, a rasterizer, a z-buffer and two frame buffers. Additional pixel memory is used for alpha blending and for storing logical information. Although their ...

This paper presents a comprehensive method to calculate object to object diffuse reflections within complex environments containing hidden surfaces and shadows. In essence, each object in the environment is treated as a secondary light source. The ...
