Help needed on Transform3D and the view plane.
Hia guys.
Im a Java3d noob that needs some help please.
What Im doing is a space game. I have rendered all the objects I want in space no problems (stations, asteroids and **** like that). I have managed to make my view rotate as I want it (pitch, yaw and roll).
vChgT3d =new Transform3D();
vSteerTG.getTransform(vT3d);
vChgT3d.set(new Quat4d(pitchRate,yawRate,currentRoll,1));
vT3d.mul(vChgT3d);
vSteerTG.setTransform(vT3d);
This works fine. The pitch yaw and roll behavior is just as I want it.
Now Im trying to create the ship movement, of my ship.
I have calculated the change in vx, vz and vz. Or rather change in locations on the x y and z axis.
I dont want to mul this to the transform as I just wana move the ammount of units that the newtonic calculations have determind. So what I *think* I wana do for this is.
vChgT3d =new Transform3D();
vSteerTG.getTransform(vT3d);
vChgT3d.set(new Vector3d(vx,vy,vz));
vT3d.add(vChgT3d);
vSteerTG.setTransform(vT3d);
Though this gives me an exception. On the last line of the code where I set the transform to the transform group.
javax.media.j3d.BadTransformException: TransformGroup: non-affine transform
Anyone know what Im doing wrong?
Thanks in advance.
