WebApr 11, 2024 · The Convex Hull operator takes a point cloud as input and outputs a convex hull surrounding those vertices. If the input contains edges or faces that lie on the convex hull, they can be used in the output as well. This operator can be used as a bridge tool as well. Input mesh, point cloud, and Convex Hull result. Web3. Combine the two hulls into overall convex hull. Part 2 is simply two recursive calls. Note that, if a point is in the overall convex hull, then it is in the convex hull of any subset of points that contain it. (Use characterization in exercise.) So the task is: given two convex hulls, find the convex hull of their union. ⌃ Combining two hulls
