I just but a new release of VisAD on the server, that
supports 3-D clipping. See visad/examples/Test35.java
for an example.
Applications can set up to six arbitrarily oriented clipping
planes using a new method of DisplayRendererJ3D:
/** define a clipping plane in (XAxis, YAxis, ZAxis) space
plane number must be in (0, ..., 5)
clip plane defined by ax + by + cz + d <= 0
*/
public void setClip(int plane, boolean enable, float a, float b, float c,
float d)
throws VisADException;
This only clips data depictions, not axis scales etc.
_From Test35.java, to clip to the usual box (i.e., x, y and
z values in the range -1.0 to +1.0), do:
DisplayRendererJ3D dr = (DisplayRendererJ3D) display.getDisplayRenderer();
dr.setClip(0, true, 1.0f, 0.0f, 0.0f, -1.0f);
dr.setClip(1, true, -1.0f, 0.0f, 0.0f, -1.0f);
dr.setClip(2, true, 0.0f, 1.0f, 0.0f, -1.0f);
dr.setClip(3, true, 0.0f, -1.0f, 0.0f, -1.0f);
dr.setClip(4, true, 0.0f, 0.0f, 1.0f, -1.0f);
dr.setClip(5, true, 0.0f, 0.0f, -1.0f, -1.0f);
Cheers,
Bill
