You can see an overview of InstaLOD's complete feature set in DP 03:19. In this issue, we look in particular at how InstaLOD can automate the workflow from CAD data from a PLM system to a real-time-ready VR model. by Calvin Bacon Computer Aided Design (CAD) data from engineering consists of nurbs curves and surfaces and cannot be rendered by most renderers. Until now, there were two options for preparing them for real-time rendering. Either a manual retopo, i.e. building the asset from scratch as a 3D mesh, or tessellation. Manual retopo is a process that can take days or weeks per scene - depending on the complexity of the models. The other option is automatic tessellation. However, since CAD data is parametric (has infinite accuracy), automatic tessellation achieves an extremely high polycount, which is practically useless for real-time rendering, and if a low tessellation is aimed for, details are often missing, curvatures are poorly modelled or get broken normals. The tessellatio...
