The Inverse Warp: NonInvasive Integration of ShearWarp Volume Rendering into Polygon Rendering Pipelines
, 2003
"... In this paper, a simple and efficient solution for combining shearwarp volume rendering and the hardware graphics pipeline is presented. The approach applies an inverse warp transformation to the ZBuffer, containing the rendered geometry. This information is used for combining geometry and volume ..."

FAST VOLUME RENDERING USING A SHEARWARP FACTORIZATION OF THE VIEWING TRANSFORMATION
, 1995
"... Volume rendering is a technique for visualizing 3D arrays of sampled data. It has applications in areas such as medical imaging and scientific visualization, but its use has been limited by its high computational expense. Early implementations of volume rendering used bruteforce techniques that req ..."

HYBRID SHEARWARP RENDERING
"... Shearwarp rendering is a fast and efficient method for visualizing a volume of sampled data based on a factorization of the viewing transformation into a shear and a warp. In shearwarp rendering, the volume is resampled, composited and warped to obtain the final image. Many applications, however, ..."

buffer. With the zlistbuffer, an objectbased scan conversion of polygons requires only a simple modification of the standard polygon scanconversion algorithm. This paper shows how the scan conversion can be integrated with shearwarp rendering of runlength encoded volume data to obtain quality images in real time
ShearWarp Shell Rendering
, 2002
"... In Medical Imaging, shell rendering (SR) and shearwarp rendering (SWR) are two ultrafast and eective methods for volume visualization. We have previously shown the fact that, typically, SWR can be on the average 1.38 times faster than SR, but it requires from 2 to 8 times more memory space than ..."

Light Field Rendering
, 1996
"... A number of techniques have been proposed for flying through scenes by redisplaying previously rendered or digitized views. Techniques have also been proposed for interpolating between views by warping input images, using depth information or correspondences between multiple images. In this paper, w ..."

ShearWarp Deluxe: The ShearWarp Algorithm Revisited
"... Volume graphics is a graphics technology that has gained immense momentum in recent years. In volume graphics the object exists discretized on a 3D raster, which is in stark contrast to polygonal graphics where the object is represented as ..."

Integrating PreIntegration Into The ShearWarp Algorithm
, 2003
"... The shearwarp volume rendering algorithm is one of the fastest algorithms for volume rendering, but it achieves this rendering speed only by sacrificing interpolation between the slices of the volume data. Unfortunately, this restriction to bilinear interpolation within the slices severely compromi ..."

A preintegrated lookup table is used during compositing to perform a substantially improved interpolation between
