Hello,
actually I am working on my master thesis about “Direct Volume Rendering in Medicine”. For this I am comparing different OpenSource Software products. Now I am researching about simulated lightning/ many light source methods in DVR. Perhaps the 3D-Slicer inlcudes such tools for a more detailed representation of volume data.
Unfortunately I can not find some information about this.
Slicer uses VTK for rendering. VTK has tons of lighting and volume rendering options in several rendering backends. In Slicer you can use most of these features. Most commonly needed features are exposed on the graphical user interface in Volume Rendering module in Slicer core and in Lights module in Sandbox extension; and you can access all other options via Python scripting using VTK API.
Let us know if you are not sure if a specific lighting method is available in Slicer or not.
