Drawing curve onto point-cloud surface
WebThe first step in a reverse-engineering workflow consists in transforming digitized point clouds into surface-based polygonal models, also called meshes. Polygonal models are more compact, more accurate, and less noisy than raw point clouds and are directly handled by industrial applications such as milling, 3D printing, and aerodynamic simulation. WebThe Project SOP creates profile curves (also known as trim curves or curves-on-surface) by projecting a 3D face onto a spline surface, much like a light casts a 2D shadow onto a 3D surface. There are two projection methods: along a vector, or mapping the face directly onto the parametric space of the surface. After a Project node you will often ...
