Visualization problem: total dark surface without gridlines

[leoforeal]

Hallo,

I tried to visualize the mesh result of o3d.geometry.TriangleMesh.create_from_point_cloud_poisson(),

mesh, densities = o3d.geometry.TriangleMesh.create_from_point_cloud_poisson(pcd_normal, depth = 10, scale = 1.1, linear_fit = False )
and somehow it displayed a darkblack surface without the gridlines of the mesh (s. screenshot), can someone explain why or how I can adjust the parameter of visualization.draw_geometries() to display a mesh with gridline and perhaps another color of the surface.

Thank you all in advance!

I get that a lot with meshes from 3D scans, which can have more than 1M edges. The mesh needs to be decimated radically before you'll see any gaps between the black wireframe edge lines.
If you ust want to see surfaces, use the pointcloud. It can be sampled from the mesh (I use uniform, 100K-1M points), compute the normals, and convert the normals to colors. It ends up looking like a nice 3D surface on most screens.
