Summary0032542: Volume Rendering - introduce Transfer Function presets for medical data sets (DICOM)
DescriptionExisting Volume Rendering interface provides a low-level editor of Transfer Function. Automated logic within Draw Harness and CT Assistant is not suitable for medical data sets (CT) and also difficult to modify to meet conventional color mapping (bones, skin, fat, muscles, etc.).

It is proposed providing a mechanism constructing a Transfer Function suitable for medical data sets.
