Avoid filling in holes when creating mesh

[jianwang]

Hello,

Is it possible to create mesh without filling in some big holes?

I created a mesh for a stair. The dense point cloud was good but the reconstructed mesh filled in the space above the stair.

Is it possible to avoid this?

Thanks!

Best,

Jian

How did you create the mesh, with depth maps or dense cloud?
