Inverse Geometry Textures
Inverse geometric textures (IGT) introduces a novel random-access parallel data-structure for interactive rendering. The key idea is to map surface and color input data to a virtual regular grid, which naturally suits for the graphics processing unit (GPU). In essence, this technique decouples surface and textures from high resolution meshes and map them onto lower resolution simpler domains, which are faster to render but still preserving the original details.
Continuity Mapping of Multi-chart Textures
Continuity mapping can make any multi-chart parameterization to be seamless, without requiring re-parameterizing the artist-provided textures, or non-accurate texturing operations like texture transfers. All with small memory and computational costs.
BRDFLab
BRDFLab is a modular system to design complex bidirectional reflectance distribution functions (BRDF). The system handles BRDFs defined in a variety of forms (analytical models, measured data, and simulation data), allows to display their shape, perform fitting, and rendering with different lighting conditions.
