Witryna19 sie 2024 · The minimum bounding box (MBB) is the box around a cloud of 3D points with the smallest volume. Joseph O'Rourke published [2] a cubic-time algorithm to find the minimum-volume enclosing box of a 3-dimensional point set. O'Rourke's approach uses a 3-dimensional rotating calipers technique. WitrynaReturns the oriented bounding box for the geometry. Computes the oriented bounding box based on the PCA of the convex hull. The returned bounding box is an approximation to the minimal bounding box.

WitrynaI have the BBox Coordinats (maxx,maxy,minx,miny), which are the MaxP and MinP of the Pointcloud and want to make a polygon out of it. With bbox_to_Polygon (MaxP,MinP) the BBox coordinates are converted into corner points. These should be used to create two polygons. Out of this i had made a Polyhedron with pyny3D.
