Currently I do it this way. It returns the picked Shape3D. Checkpos is the xy-position on the screen you want to check for hits:
1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
16
17
18
19

| View mYourview = ... this is your view object.
public Node pickit(Point checkpos)
{
PickRenderResult[] result = mYourview.pick(mYourview.getCanvas3D(0), checkpos.x, checkpos.y, 2, 2);
if (result == null) {
return null;
}
Node node = null;
int zbest = 0;
for (int i = 0; i < result.length; i++) {
PickRenderResult restmp = result[i];
int zmin = restmp.getZMin();
if (zmin < zbest) {
zbest = zmin;
node = restmp.getNodes()[0];
}
}
System.out.println(result.length + " hit objects.");
return node;
