I’m trying to use slicer to visualize tracks. My diffusion volumes were 275x225x450 with 0.2mm voxels.
Has anyone explored the limits of track visualization? Memory usage appears strangely high when I load in my tracks, the vtk fiberbundles are less than 1GiB on disk, but use 25+GiB in RAM.
My total number of tracks may be high, it seems to indicate I’m loading 200,000+ tracks in about 20 different vtk fiberbundle files. Some of which have 45,000, others having only 200-1000.
When these tracks are initially loaded the interface is frustratingly slow/laggy, even after disabling the display modules. I’ve tested in slicer 4.6, 4.8, and nightly of 2018-02-06. After saving and loading all tracks and the scene, and switching visualization to lines colored by segment, instead of tubes, the interface behaves reasonably.
