Voxels and streamlines

Voxel-based volumes and triangle-based meshes can exist together in the same scene. NiiVue considers tractography streamlines as a special class of meshes. Note that the mesh_xray effect allows you to visualize meshes that are beneath the surface of the volume rendering. The more advanced tracts notebook illustrates ways that you can modify streamlines appearance.
