oSP3D can import CSV-formatted 3D grid data files. In addition to the specification requirements and limitations summarized in CSV Files, the CSV import interface adds these requirements:
No header line
3 columns ( x, y, and z)
3D grid is parametrized by three axes in Cartesian x, y, and z direction
Dimension of the grid is auto-detected
Grid points are ordered as in the following example. First the x coordinates are changed while keeping y and z constant, and then y is increased while keeping z constant. Lastly, z is increased.
-1.00;-1.00;1.00 0.00;-1.00;1.00 1.00;-1.00;1.00 -1.00;0.00;1.00 0.00;0.00;1.00 1.00;0.00;1.0 -1.00;1.00;1.00 0.00;1.00;1.00 1.00;1.00;1.00 -1.00;-1.00;2.00 0.00;-1.00;2.00 1.00;-1.00;2.00 -1.00;0.00;2.00 0.00;0.00;2.00 1.00;0.00;2.0 -1.00;1.00;2.00 0.00;1.00;2.00 1.00;1.00;2.00
