Example 5: Volume rendering and interactions
Introduction
In this example we like to convert a scan of a head into a 3D scene-object. The scene-object allows to add some textures, interactions and animations.
Steps to do
Develop your network
Implement the following network and open the image $(DemoDataPath)/BrainMultiModal/ProbandT1.tif.
The module SoGVRVolumeRenderer allows volume rendering of 3D and 4D images.
Example 6: MeVis Path Tracer
Example 6: MeVis Path Tracer
Introduction
The MeVis Path Tracer offers a Monte Carlo Path Tracing framework running on CUDA GPUs. It offers photorealistic rendering of volumes and meshes, physically based lightning with area lights and soft shadows and fully integrates into MeVisLab Open Inventor (camera, depth buffer, clipping planes, etc.).

Example 6.1: Volume Rendering vs. Path Tracer
Introduction
In this example you develop a network to show some differences between volume rendering and the MeVisLab Path Tracer. You will visualize the same scene using both 3D rendering techniques and some of the modules for path tracing.
The MeVis Path Tracer requires an NVIDIA graphics card with CUDA support. In order to check your hardware, open MeVisLab and add a SoPathTracer module to your workspace. You will see a message if your hardware does not support CUDA:
