Point cloud data files must be plain text files in one of two
formats: XYZ or Grid.
A point cloud data file in XYZ format must
contain the desired field values at a set of coordinates. For a rectangular
coordinate system, the points must be given by X-,
Y-, and Z-coordinates. If you use a
cylindrical or spherical local coordinate system, the appropriate coordinates
must be used. The Grid format contains field values at
points in a three-dimensional grid.
Abaqus/CAE
interpolates to fill in any missing field values in your grid data
files.
