isosurface tetrahedra question.... [message #67933]

Hi there,

I'm trying to create an isosurface of some 3D data and then render it
using IDLgrPolygon.

OK, so I have my 3D dataset of scalar values. At each point I have
the X,Y, and Z coordinates which I've combined to make
my GEOM_XYZ array....

so here I go:

isosurface,Data_3d,
0.5e-18,Outverts,Outconn,geom_xyz=GEOM_XYZ.......... err, tetrahedra
= ?

I don't understand what else is needed - but apparently tetrahedra
needs to be defined as well (another array).

Can anyone please tell me what the tetrahedra array is ?

Cheers

George.
