Why doesn't VRMesh run properly on my computer?
Please check that your computer satisfies the recommended requirements to run VRMesh. If it does and you experience a crash on startup, or a very slow interaction in the middle of operation, please update your graphics card drivers.

How to set VRMesh to its default settings?
You should hold down [Shift] while launching VRMesh.

Can VRMesh handle very large datasets?
VRMesh can handle large datasets in excess of one billion points. The program has no limit to the size of point clouds.

Will the coordinate system of point clouds/meshes be changed while processing?
No, the coordinate doesn't change while processing point clouds/meshes in VRMesh, so you can export point clouds/meshes at the same coordinates.

How to import large point clouds into VRMesh?
There are two commands that can be used to read a point cloud file. The Import command (File > Import) imports all data into the window. The Index/Attach command (File > Index/Attach) allows you to create an index file from a point cloud file and attach it to the current project, which only retrieves inquiring points into the window. Depending on your computer setting, you may choose to index/attach a point cloud file into the window if it contains more than 3 million points.

What import/export formats can VRMesh support?
Import: e57, las, laz, ptx, pts, asc, stl, obj, dxf, shp, ply, zfs, rdbx, wrl, vtk, csv, rcp, step, iges, ifc, landxml
Export: las, laz, pts, asc, iges, stl, obj, dxf, fbx, shp, grid, wrl, ply, vtk, csv, x3d, pdf, rcp, landxml, nwc, gltf

How accurate is VRMesh?
VRMesh uses double-precision floating-point numbers to retain all of the accuracy of the original input data.

Why is an item marked with an asterisk in the Object Tree Window, e.g., *Object?
It means that the object is an indexed file and attached to the project, which allows you to load the point cloud data with a preferred size into the window.

Why is an item marked with a pound sign in the Object Tree Window, e.g., #Object?
It means that the object has a constraint added on by a widget box. Only part of the data is displayed in the window. You may use the Reset command (Home > Reset) to remove the constraint.
