Abstract
The present disclosure provides a system and method for the development and manipulation of three-dimensional voxel-based models. The method includes accessing, by a processor of a computing device, a subdivision surfacing geometry (SubD) model and converting a portion of features of the SubD model to a voxel model. The method includes accessing a texture for application to the voxel model and combining the texture and the voxel model to create a textured voxel model. The method includes determining displacement maps determined based in part on a difference between a surface portion of the voxel model and a surface portion of the SubD model and applying the displacement maps to the surface portion of the SubD model to determine a second SubD model where the second SubD model is configured for manipulation while preserving a visual aesthetic and a geometric placement of the added texture.
