Hi Hamish Harvey
I have so far only seen the mesh once exported, but surely the mesh must be built before texturing takes place? So it’s available internally even if not shown - but the “solid” and “textured” view options don’t seem to be available.
Yes it is not implemented yet, but with our actual viewing engine you can inspect models up to 50 billion triangles.
If I understand correctly, this behaviour of closing the mesh means that I’m better reconstructing with no or large region, then reducing the region and filtering out everything outside the new region. That will remove … I guess vertices outside the region, and any triangle for which that is a vertex?
Yes, set the bounding box (BBox) to a “reasonable” size in oder not to create too much artificial geometry, and if it creates it, then it is easy to remove it with the BBOX and FILTERING tool.
Also, it leads to mesh surface being constructed which is entirely synthetic (i.e. not based on anything in the inputs), which is perhaps fine if you’re interested in a visual output only, but a problem if using this as a measured survey technique.
This will be solved in a next improvement of meshing algorithm…
I suppose that means we need to filter the mesh using an external tool, to remove all triangles with edges over a threshold length (which is what I’ve done with meshes built in Meshlab before). That will mean either using an external tool for texturing as well, or bringing the mesh back into RC after filtering to do the texturing - if that is possible. Again, a much more awkward workflow.
As I have mentioned, you can use the FILTERING tool inside RC to remove what you need.
Is this something that you anticipate addressing in future development?
