Menu: Files->Import->XYZ nodes...
Reads a set of points from an text file. It reads also compressed text files.
Several options can be adjusted in the import file dialog box:

By default, lines with three real numbers separated bu spaces are imported.

...

• Comments starts with: specify the comment character to skip lines, for instance # will skip lines starting with this characted

• Format of lines: if the coordinates of the points are defined in a specific format, the user can enter here a C/C++ string format to parse the coordinates, for instance:

%g %g %g will read X Y Z coordinates separated by spaces
%g, %g, %g will read X Y Z coordinates separated by commas
%*d %g %g %g will read X Y Z coordinates after discarting the first 'index'

• Create delaunay mesh after import: if enabled, after importing the points a triangle / tetrahedral mesh will be created using the delaunay mesher.

Menu: Files->Import->Collada...
With this option it is possible to read collada mesh files, with .dae extension.
COLLADA (COLLAborative Design Activity) is an interchange format, xml-based for interactive 3D applications.
This importer is implemented as a pure Tcl plugin, with limited features.
It allow to import it as a regular mesh, otherwise the mesh data and attached textures is handled at Tcl scripting variables level, and the textures are drawn on the mesh.
