Efficient visibility-driven medical image visualisation via adaptive binned visibility histogram

Visibility Driven Rasterization

We present a new visibility driven rasterization scheme that significantly increases the rendering performance of modern graphic subsystems. Instead of rasterizing, texturing, lighting, and depth-testing each individual pixel, we introduce a two-level visibility mask within the rasterization stage which facilitates the removal of groups of pixels and triangles from rasterization and subsequent ...

Hardware-driven visibility culling

Visibility Driven Rasterization

Cotton-picker dataset containing 10 million triangles. Occlusion culling in z-buffer systems has drawn a lot of attention over the last few years.1,3 Due to the high computational costs of occlusion queries, hardware support is required to accelerate interactive rendering. This requires mechanisms that fit nicely into an available graphics subsystem without greedily consuming chip real estate (...

Landscape Visibility Analysis and Their Visualisation

Visibility analysis or Viewshed is a common function of almost all GIS systems. The aim of this project is to find out the best solution, to compute viewshed for the Olomouc region and ensure the best way of visualisation of the results. The first step to analyze the visibility is making a high quality Digital Terrain Model, choice of the best interpolation method and subsequent addition of veg...

Adaptive Quantization Visibility Caching

Ray tracing has become a viable alternative to rasterization for interactive applications and also forms the basis of most global illumination methods. However, even today’s fastest ray-tracers offer only a tight budget of rays per pixel per frame. Rendering performance can be improved by increasing this budget, or by developing methods that use it more efficiently. In this paper we propose a g...
