Hi
You have to initialise a pick canvas object and reference it to the canvas3D
and the locale (or branch group) in your scene graph.
Then use pick result to get pick intersection information
from this you can get any information from the screen
If i remember this is the code- think it may be a little bit wrong- check
the j3d docs.
PickCanvas pickCanvas = new PickCanvas(canvas3D,locale);
pickCanvas.setTolerance(0.5f);
pickCanvas.setMode(????) - cant remember exact code- look in j3d docs
PickResult[] pickRes = new PickResult(--think pickCanvas goes here
PickIntersection pi = pickResult[0]; ??
then use pi to get the information you want - again look at the method
descriptors for the PickIntersection class.
Apologies if this code is a little unclear - i cant remember the exact code
- i'll post it later on.
But with the pi object you can enquire - a point picked on a shape - the
vertices making up the face of a shape picked - a GeometryArray object from
a shape - etc
