Viewing mesh/point cloud in vizard
 

Hi guys,
I've been struggling for a few weeks now trying to view a point cloud in vizard. I am completely new at this and not sure where to start.

I have an ASCII point cloud that I start with and turn to a mesh that I then save as .3ds and/or .obj in MeshLab using the following directions:

1. Filters -> Normals, curvatures and orientation -> Compute normals for point sets
2. Filters -> Remeshing, Simplification and Reconstruction -> Surface Reconstruction
3. Filters -> Texture -> Parametrization: Trivial Per-Triangle
4. Save (as .3ds or .obj)

I've tried saving it directly as a point cloud to .3ds in MeshLab but I get various errors and can't do that, hence turning it into a mesh.

I've even gone into Vizard inspector with the .obj file and turned it into an .osgb file

Then in Vizard, I use the following code to attempt to view the mesh:
import viz
viz.go(viz.FULLSCREEN)
viz.add('piazza.osgb')
import vizcam
vizcam.WalkNavigate()
where I just replaced the default piazza file with my file. The default works, but when I put my files in there, I just get a black screen with nothing on it.

I get no errors when using any of my files, I just don't see anything on my screen.

I don't have a raster on top of my mesh. Could this be the problem?

Any help would be greatly appreciated.

If the file is text based and in x,y,z or x,y,z,r,g,b, format, try renaming the extension to .3dc and then loading it in Inspector or Vizard.
