3D Visualization & Volume Rendering

3D-DOCTOR provides several methods for volume rendering . The rendered 3D volume can be visualized in real time at any viewing angle thanks to the efficient ray-tracing algorithms implemented in 3D-DOCTOR. Either the entire image volume, a portion defined by regions of interest (ROI), or image portions defined by object boundaries can be used to create volume rendering.

The following lists the 3D volume rendering methods supported:

1. Grayscale with Opaque Voxels:  Image voxels are treated as opaque and ray traced and shaded using grayscale values.
2. Grayscale with Transparent Voxels:  Voxels are treated as transparent and ray traced to create 3D rendering. 
3. Color with Opaque Voxels:  Color shading is applied on opaque voxels in volume rendering.  
4. Color with Transparent Voxels:  All voxels are treated as transparent in the ray-tracing process and color shading is applied. Colors can be changed interactively.
5. User-Defined Color Map: Volume rendering using a color map defined based on voxel values.
