trimesh.convex#
convex.py
Deal with creating and checking convex objects in 2, 3 and N dimensions.
Convex is defined as: 1) “Convex, meaning “curving out” or “extending outward” (compare to concave) 2) having an outline or surface curved like the exterior of a circle or sphere. 3) (of a polygon) having only interior angles measuring less than 180
- trimesh.convex.adjacency_projections(mesh)#
Test if a mesh is convex by projecting the vertices of a triangle onto the normal of its adjacent face.
- Parameters:
mesh (Trimesh) – Input geometry
- Returns:
projection – Distance of projection of adjacent vertex onto plane
- Return type:
(len(mesh.face_adjacency),) float
- trimesh.convex.convex_hull(obj, qhull_options='QbB Pp Qt', repair=True)#
Get a new Trimesh object representing the convex hull of the current mesh attempting to return a watertight mesh with correct normals.
- Details on qhull options:
- trimesh.convex.hull_points(obj, qhull_options='QbB Pp')#
Try to extract a convex set of points from multiple input formats.
- Parameters:
obj (Trimesh object) – (n,d) points (m,) Trimesh objects
- Returns:
points
- Return type:
(o,d) convex set of points
