Volume rendering

Key classes

Format of Volume Property (.vp) file

Volume properties, separated by newline characters.

Example:

1 => interpolation type
1 => shading enabled
0.9 => diffuse reflection
0.1 => ambient reflection
0.2 => specular reflection
10 => specular reflection power

4 0 1 255 1 => gradient opacity transfer function (total number of values, each control point is defined by a pair of values: intensity gradient and opacity)

Examples

Examples for common operations on transform are provided in the script repository.

Volume rendering presets

Volume rendering presets that are bundled in Slicer core are specified in a preset file and corresponding icon is stored as an application resource.

To add a new volume rendering preset:

Presets can be also added at runtime - see example in the script repository. In this case, icons are loaded from the preset scene file.
