How can I coax IDL 4.0.1 to show an isosurface as if the volume inside
would be filled? It should look like a solid and not a hollow thing.
The data is a 3-D-fltarray filled with floating point skalars with
values between 5 and 15: data=fltarr(80,80,80)
In this special case the values inside the isosurface are higher than
outside.
I tryed the following two ways:
1.) close the openings due to the cutting with the faces of the unit
cube with a filled
contour plot
- but how to adjust the filling colour of the contour plots to the
shading of the
isosurface?
2.) to "digitalise" the fltarray, i. e. make an 3-d-intarray filled with
0 at the
places, where the value of data is LT "threshold" and filled with 1
where the value
of data is GE "threshold"
- but the shade_volume command produces a bad "poly" for the
polyplot.
I would be happy about any advice
