Unlike prior methods, our technique avoids costly clustering operations, significantly reduces data structure construction cost, and incurs less overhead when traversing active regions.Human centered computingScientific visualizationVisualization techniquesComputing methodologiesRay tracingGraphics processors10.2312/pgv.2021104237-44
