Slicer Training Volume Rendering

Volume Rendering

Get It Running

1. To get volume rendering to work within 3D Slicer we have to make sure that a MRML node with Volumetric Data exists.
2. If not a new set of volume data must be loaded. For this demo we will load the tutorial data found here.
   1. Download and Uncompress this folder
   2. In 3D Slicer go to File -> Load Scene
   3. Select the tutorial.xml
3. Now select the VolumeRendering Module.
4. Select a valid volume as the Source Volume
   

   Select Scanner in Volume Rendering Module

The Volume Rendering will be initialized. Have patience....

Parameters

Performance Triggers

Volume Rendering - Performance

You can adjust the performance of volume rendering by enabling and disabling quality improvements. The Volume Rendering Module has three performance levels

1. Low Resolution Hardware Rendering (worst - fastest)
2. Full Resolution Hardware Rendering
3. Software Rendering (best - slowest)

When all of them are selected slicer uses the low resolution when the camera is moving or nodes in the scene are changing and when nothing is changing anymore the high resolution volume is performed.
