X-ray volume rendering through two-stage splatting

Westenberg M. A., Roerdink J. B. T. M.

Machine Graphics and Vision

2000

Vol. 9, No. 1/2

307-314

We consider the splatting method for X-ray rendering of volume data sets, and introduce two-stage splatting. This variant improves rendering speed by separating the splatting process in two stages: coefficient accumulation and convolution. We incorporate this variant into wavelet splatting, and obtain speedups in rendering time up to a factor of three for Haar and B-spline wavelets.

Optimising ray tracing for visualisation of volumetric medical image data

Lorang T., Schuster E., Gengler M., Prinz M.

Machine Graphics and Vision

1999

Vol. 8, No. 4

691-697

The presented optimizations provide an approach to fast rendering of medical volume data. They are based on the ray casting algorithm, which is substantially speeded up with regard to voxel addressing and interpolation.
