Geometry Selection

open the geometry selection window

Once the geometry is created or imported, the user must define which parts of the geometry will be taken into account during the computation. This functionality has 2 aims :

in case of huge geometries, the computation time can be decreased by ignoring parts of the geometry which would probably not interact with the source (inside parts, deep shadow parts,...)

for physical insight into scattering process.

The whole geometry may be selected with the 3 buttons : Select all the vertices, Select all the edges, Select all the surfaces

The button Select/Deselect some entities open a special window which enables the user to assign/unassign single geometrical parts to the selection.

The Draw utility gives an easy graphical check of the selection. In the following example, only the surfaces representing the wings were selected :
