Did you construct Gridded3DSets with manifold dimension = 1,
or just ordinary manifold dimension = 3? You can essentially
draw lines in 3-D as Gridded3DSets with manifold dimension = 1.
See visad/examples/DelaunayTest.java, particularly lines 209 to
256.
Good luck,

Hi Bill,
first of all, thank you for the time you spend on my problem. Yes i used
a Gridded3DSet with manifold dimension = 1, but what i get is not what i
need. To explain you what the problem is, i have attached a very simple
2D example (in 3D it's allways the same). When you look on the picture
you can see the grid i have to visualize. These are results from CFD
codes (Computational Fluid Dynamic). The circle is (in this example) the
geometry that was analyzed in a specific fluid flow )This is the reason
why no points are defined within the circle, the flow goes arround the
geometry). In this case each quadrilatral is a computing cell, a so
called "volume". The connections between the points are given by a
connecting list where each quadrilateral is defined by 4 indizes. From
this connecting list it is common to create an IndexedArray. So i think
this is the easiest way. If there is no easy way to get the scaling from
VisAD, could you explain me where VisAD set the scaling? Maybe i can
extract the transform with this information.
To pass my data into VisAD i rebuild my connecting list, from
quadrilateral or hexahedron to triangle or tetrahedron, and create a
DelaunayCustom with it.
Another question in this context is, are there any limitations in
displaying streamlines? As i explained, i am using an Irregular3DSet for
my data. A few days ago i played arround with Display.FlowXX and
FlowXControl. The vector plot works, but when i switch to streamline
nothing happened.
Thanks
Olav
