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.

Other limitations of this ray caster include that:

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

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.

What is the image sample distance required to achieve the desired time? A version of this method is provided that does not require the volume argument since if you are using an LODProp3D you may not know this information.

If you use this version you must be certain that the ray cast mapper is only used for one volume (and not shared among multiple volumes)
