Efficient rendering of anatomical tree structures using geometry proxy

Rendering tubular structures efficiently is crucial for studying anatomical tree structures like vessels or airways. Most existing methods are based on surface reconstruction, resulting in complex meshes, which slows the rendering performance as the tree complexity increases. In this paper, we present an approach to render tubular tree structures using geometry proxy. We generate low complexity proxy meshes on the fly and shade the meshes as tubular objects consisting of truncated cones and spheres. Unlike surface reconstruction, our method requires no precomputation and produces appealing imagery with faster rendering performance.
