Hi Muz, > Thanks for replying. > I tried to use the Linear3DSet in a Cylindrical Coordinate system and > rendered the 3D-volume. > However, the display is not as "solid" as the Linear3DSet in Cartesian > coordinate system. > Is there any way I can make it continuous filled on the rendering? > I got picture for cube and cylinder rendering like this: > http://129.237.87.25/~lcheng/volumeJpg.html > They are based on Tutorial example 10. The unit scale for azimuth > is 360.0 and the number of samples for azimuth component is 100. You need to use a Linear3DSet in Cartesian coordinates. Since that is not the natural sampling of your data, you will need to resample your FlatField to such a Linear3DSet. If a FlatField has a domain Set in (r, theta, z) and (x, y, z) is the reference for (r, theta, z), then you can resample() it to a Set in (x, y, z).
