[ff3d-users] VRML input and complicated shapes

[Dimitrios Eftaxiopoulos]

Hello,
just two questions.

1) Can freefem3d handle complicated geometrical shapes, e.g a bone?

2) VTK exports scenes in the VRML format, not the POV format. Will it be
possible in the future to import VRML format scenes in ff3d directly?

Regards

Hello Dimitrios,

Yes. The question is how do you plan to get this geometry? There are two ways
in ff3d to deal with complex geometries:
- using the fictitious domain approach
* using a POVRay description, or
* using the characteristic function of the domain (a function which is 1
inside the domain and 0 outside)
- using an unstructured grid generated by an external tool. Two formats are
recognized (the INRIA mesh format and gmsh format).

Well. This might occur once, but up to now the POVRay format is not complete
in ff3d and this is not something I planed to do soon. Consider that if no
one takes this task it will not occur (soon).

Best regards,
Stéphane.
