Thanks wagster,
for your response and support.
and I confirm that your understanding it correct on my requirement.
In simple words, visually light should remain fixed no matter how and
where camera pointing.
so, I need to move the light.direction based on camera movement, so
end result should look like that light is coming from same direction
no matter how camera is placed.
it is like, binding light direction with camera position.
I got the Camera direction using suggested call..
and now trying to figure out the difference between camera direction
and the light direction, but with no success.
I tried it as following:
//****************************************
// initial light direction
dLight.direction = new Vector3D(-1500,-600,-1000);
// in Enterframe event, before view.render() call, I am trying to
calculate and set the light direction
var obj:Vector3D = Matrix3DUtils.getForward(camera.transform);
trace('obj:'+obj.x+', '+obj.y+', '+obj.z);
dLight.direction = new Vector3D(-1500-obj.x,-600-obj.y,-1000-obj.z);
//****************************************
I would truly appreciate if you may lead further to resolve this
issue.
Thanks
