Dan,
Yup... my code works FINE with only a single link to the SG.
My code was used successfully for a project last year.
Can you tell me what is wrong with this code:
TransformGroup bushes = new TransformGroup();
Vector3f translate = new Vector3f();
Transform3D T3D = new Transform3D();
TransformGroup TGT;
public PlaceBushes() {
bushes.setCapability(TransformGroup.ALLOW_TRANSFORM_WRITE);
bushes.setCapability(TransformGroup.ALLOW_TRANSFORM_READ);
SharedGroup sg = new SharedGroup();
String filename = "/pernica/images/bush.gif";
OrientedShape3D bush = new OrientedPlane(filename,1,1,1); // 1 meter
by 1 meter placed 1 meter high
bush.setAlignmentAxis( 0.0f, 1.0f, 0.0f); // unnecessary
sg.addChild(bush);
float[][] position = {
{0,0,-50}, // markers for distances
{0,0,-100},
{0,0,-150},
{0,0,-200},
{0,0,-5}, // To demo transparency problems
{0,0,-7},
{0,0,-9},
{0,0,-11},
{162,0,-199}, // 2nd Floor walkway corners
{200,0,-248.5f},
{286,0,-199},
{248f,0,-248.5f},
{162,18,-199}, // 4th Floor walkway corners
{200,18,-248.5f},
{286,18,-199},
{248f,18,-248.5f},
{142.5f,0,-224}, // near west bench
{137.5f,0,-224},
{195,0,-289} // last one inside north store
};
for (int i = 0; i < position.length; i++){
translate.set(position[i]);
T3D.setTranslation(translate);
TGT = new TransformGroup(T3D);
TGT.setCapability(TransformGroup.ALLOW_TRANSFORM_WRITE);
TGT.setCapability(TransformGroup.ALLOW_TRANSFORM_READ);
TGT.addChild(new Link(sg));
bushes.addChild(TGT);
}
}
Thank you.
