Segment Tracing & Implicit Blocks papers

July 09, 2020

Our paper Modeling Rocky Scenery using Implicit Blocks has been accepted to The Visual Computer and will be presented remotely at CGI2020. This work is an extension of our paper Terrain Amplification using Implicit 3D Features presented in 2019 at Siggraph Asia. We show how to create meso and micro scale details in volumetric terrains with new implicit primitives and operators. We also show how to generate different types of rocky cliffs based on archetypes identified in geomorphology.

The second paper is Segment Tracing using Local Lipschitz Bounds, which was presented at Eurographics 2020. In this work, we introduce a new algorithm, Segment Tracing, for rendering implicit surfaces based on local lipschitz bounds computation. We show how to compute such bounds for skeletal primitives, affine transformations and more complex warping operators. We compare our work to standard sphere tracing and shows improvements in terms of field function evaluation and rendering time.
