[Papervision3D] Animating camera to target

I'll vote for that. Its kind of strange/non-intuitive that you pass width and height to the constructor but can't access these properties directly

it will work on anything with a geometry property.the do3d with a number of planes does not have its own geometry.the next step would be a recursive fucntion that fround the collective bounding box of all the bounding boxes using traslation matrices etc. but im no zupko. enjoy the plane.i will make other SmartPrimitives and a SmartDAE at some point, but if you beat me to that please post them to the list.OR, we could make enough noise and convince the pv3d elders that even though technically width height and depth properties are misleading on 3d geometry, they are familiar interfaces to needed information and build them into the primitives?

You have saved me a ton of headache...or at least resolved so many issues....BUT, it seems to only work with prmitives...correct? I ask because i stacked a bunch of planes into a do3D, but get an error when i try:
trace((dodd.geometry.aabb.maxY - dodd.geometry.aabb.minY)*dodd.scaleY);

happy to help.i use a custom class called SmartPlane instead of Planewhich has width and height propertiesi have attached it. enjoy.

there is no width property of Plane.
try the following:function getPlaneWidth(p:Plane){	with(p){		return (geometry.aabb.maxX - geometry.aabb.minX)*scaleX	}}On Jun 23, 2009, at 11:06 AM, montey wrote:
Thanks Gordon,

I can't seem to be able to get the width of the evt that was clicked on. I
set my click event on the plane  When I try to do a call like this it throws
an error.
My plane consists of a bunch of color materials. which are  set to be
interactive = true

Property width not found on org.papervision3d.objects.primitives.Plane and
there is no default value.

		private function onPlaneClick( evt : InteractiveScene3DEvent ) : void
		{
			//camera.lookAt(evt.target as Plane);
			var targetPlane : Plane = evt.target as Plane
			trace("evt.target = "+targetPlane.width)
			/*var xpos:Number = evt.target.x - evt.target.width/2;
			var ypos:Number = evt.target.y - evt.target.height/2;
			var zpos:Number =  evt.target.z - 100;
			TweenMax.to(camera, .8, {x:xpos, y:ypos, z:zpos, ease:Expo.easeOut});
			camera.lookAt(evt.target as Plane);
			*/

			trace("camera target = "+camera.target);
		}

If I have understood what you are trying to do, then try this;
interactiveScene3DEvent.target is the plane clicked on;

var xpos:Number = iS3DEvent.target.x - iS3DEvent.target.width/2;var
ypos:Number = iScene3DEvent.target.y - iS3DEvent.target.height/2;
zpos:Number = iScene3DEvent.target.z - 100;

Tweener.addTween(camera, {x:xpos, y:ypos, :z:zpos, time:1});
hth

Subject: [Papervision3D]  Animating camera to target

I have 20 planes positioned with z spacing what I'm trying to do is move
the
camera through all my planes as the user clicks on each plane. I'm trying
to
figure out how to do that. I tried setting the camera target to the
clicked
plane but that didn't work. I just want to tween the camera through each
plane like a fly through.

Any ideas please.
