Artifact-Free Cloud-Based CAD Rendering
Abstract:

Cloud computing for mechanical CAD provides centrally stored and synchronized models for concurrent engineering. For compactness, trimmed parametric NURBS surface representations are optimal for data transfer to client devices, which must evaluate and render models locally. Direct GPU rendering without pre-tessellation is an attractive solution in this context, both for speed and to preserve fidelity to the original geometry. However, existing data-parallel direct rendering approaches for NURBS suffer from rendering artifacts at trim boundaries. This talk proposes a solution to address these rendering artifacts that are still preventing wide-scale adoption of all such direct rendering algorithms for trimmed parametric models.
