Abstract
A Sparse Voxel Directed Acyclic Graph (SVDAG) is an efficient representation to display and store a highly-detailed voxel representation in a very compact data structure. Yet, editing such a high-resolution scene in real-time is challenging. Existing solutions are hybrid, involving the CPU, and are restricted to small local modifications. In this work, we address this bottleneck and propose a solution to perform edits fully on the graphics card, enabled by dynamic GPU hash tables. Our framework makes large editing operations possible, such as 3D painting, at real-time frame rates.
