Detailed Description

A fixed point mapper for volumes.

This is a software ray caster for rendering volumes in vtkImageData. It works with all input data types and up to four components. It performs composite or MIP rendering, and can be intermixed with geometric data. Space leaping is used to speed up the rendering process. In addition, calculation are performed in 15 bit fixed point precision. This mapper is threaded, and will interleave scan lines across processors.

WARNING: This ray caster may not produce consistent results when the number of threads exceeds 1. The class warns if the number of threads > 1. The differences may be subtle. Applications should decide if the trade-off in performance is worth the lack of consistency.

This mapper is a good replacement for vtkVolumeRayCastMapper EXCEPT:

it does not do isosurface ray casting
it does only interpolate before classify compositing
it does only maximum scalar value MIP

The vtkVolumeRayCastMapper CANNOT be used in these instances when a vtkFixedPointVolumeRayCastMapper can be used:

if the data is not unsigned char or unsigned short
if the data has more than one component

This mapper handles all data type from unsigned char through double. However, some of the internal calcultions are performed in float and therefore even the full float range may cause problems for this mapper (both in scalar data values and in spacing between samples).

Space leaping is performed by creating a sub-sampled volume. 4x4x4 cells in the original volume are represented by a min, max, and combined gradient and flag value. The min max volume has three unsigned shorts per 4x4x4 group of cells from the original volume - one reprenting the minimum scalar index (the scalar value adjusted to fit in the 15 bit range), the maximum scalar index, and a third unsigned short which is both the maximum gradient opacity in the neighborhood (an unsigned char) and the flag that is filled in for the current lookup tables to indicate whether this region can be skipped.

Automatically compute the sample distance from the data spacing. When the number of voxels is 8, the sample distance will be roughly 1/200 the average voxel size.
