Volume Rendering Techniques for General Purpose Graphics Hardware
Christof Rezk-Salama
Background
Interactive direct volume rendering has yet been restricted to high-end
graphics workstations and special-purpose hardware, due to the large amount
of trilinear interpolations, that are necessary to obtain high image quality.
Implementations that use the 2D-texture capabilities of standard PC hardware,
usually render object-aligned slices in order to substitute trilinear by
bilinear interpolation. However the resulting images often contain visual
artifacts caused by the lack of spatial interpolation. In this paper we
propose new rendering techniques that significantly improve both performance
and image quality of the 2D-texture based approach. We will show how multi-texturing
capabilities of GeForce Family are exploited to enable interactive
high quality volume visualization on low-cost hardware. Furthermore we
demonstrate how this hardware can be used to efficiently render shaded
isosurfaces and to compute diffuse illumination for semi-transparent volume
rendering at interactive frame rates.
