With the current, fast-paced advances in imaging and tractography techniques, streamlines files are poised to become incredibly massive. With this increased size comes challenges for real-time visualization and selection of streamlines. To be able to overcome those challenges, we propose a new load-time simplification mechanism, which allows loading and interactively working with files containing millions of streamlines without any visual artefact. This mechanism also implies updating the fiber selection mechanisms, to make sure that no streamline goes missing. We show that our updated selection technique allows interactive selection on huge datasets, while still providing exact selection results.
