Crop Surface Mesh Using a Bounding Box

Open Live Script

Read a surface mesh from a PLY file into the workspace.

fileName = fullfile(toolboxdir("lidar"),"lidardata", ...
           "surfaceMesh","sphere.ply");
sphereMesh = readSurfaceMesh(fileName);

Display the surface mesh.

removeDefects(sphereMesh,"unreferenced-vertices")
surfaceMeshShow(sphereMesh,Title="Original Mesh")

Define a bounding box to crop the sphere mesh to its lower half.

bbox3d = [-1 1 -1 1 -1 0];
crop(sphereMesh,bbox3d)

Display the cropped mesh.

removeDefects(sphereMesh,"unreferenced-vertices")
surfaceMeshShow(sphereMesh, Title="Cropped mesh")

`mesh` — Surface mesh
`surfaceMesh` object

Surface mesh, specified as a surfaceMesh object.

`bbox` — 3-D bounding box dimensions
six-element vector
