Efficient Culling Techniques for Interactive Deformable NURBS Surfaces on GPU

NURBS (*Non-uniform rational B-splines*) surfaces are the standard freeform representation in Computer-Aided Design (CAD) applications. Rendering NURBS surfaces accurately while they are interactively manipulated and deformed is a challenging task. …

Interactive Rendering of NURBS Surfaces

NURBS (*Non-uniform rational B-splines*) surfaces are one of the most useful primitives employed for high quality modeling in CAD/CAM tools and graphics software. Since direct evaluation of NURBS surfaces on the GPU is a highly complex task, the …
