Interactive Ray-tracing Based on OptiX to Visualize Signed Distance Fields
Taejung Park, Yangmi Lim · Advanced Science and Technology Letters · 2013
We propose a parallel ray-tracing technique to visualize signed distance fields generated from triangular meshes based on NVIDIA OptiX. Our method visualizes signed distance fields with various distance offset values at interactive rates (2–12 fps). Our method utilizes a parallel kd-tree implementation to query the nearest triangle and the sphere tracing method to visualize the implicit surface.
