Fiblets for Real‐Time Rendering of Massive Brain Tractograms

Abstract

Real-time rendering (40ms/frame) of a 64GB brain tractogram containing 3 million of individual fibers (5.37 billion segments) compressed down to 7GB. From left to right, the figure shows the rendering using different shadings (solid color, fiber orientation, per-fiber color), the ability for our pipeline to perform interactions with occlusion meshes (here with a cube mesh), and the per-fiber interaction capabilities with a selection (combined here with an occlusion mesh).
