Subject: Re: [Papervision3D] How to orbit to a point
Hi Andy. This is slightly more complicated than it at first appears although I'm sure you would have a very elegant solution. The simplest way to describe the problem is like so ...
I have objects being spawned that then need to point to a target in 3D space and start to travel to this point but not directly. Their behaviour needs to appear erratic so I am attempting to move them in an arc towards this point. I don't want to tween on a bezier because a few ticks later they need to change course slightly (but still heading towards the target).
Imagine firing a missile from one point to another but the missile is drunk!

Just use camera.orbit(pitch, yaw) where those are absolute values of where the camera should be around an object.
0, 0 is the top of the object (straight up), so to rotate around the objects side:
camera.orbit(90, yaw++); //onEnterFrame
position the camera the distance you want from the object prior to calling this.
Quats and such aren't the best/fastest solution here :P

Yea, I did ... well I left a comment on that post anyway. I'll keep on trucking then and see what I can cobble together.
Thanks! (LOL ... I read your blog)

Although I think this may be over-complicating the matter too much.

Hi John. Thanks for the response. I'm trying to create a 3D version of the 'Swarm' class from Joshua and Branden's new Hype framework. At the moment the way this works (in 2D) is that each object has a target point that it tries to get to but it attempts to get there by following a circular path which has a bit of randomness to it to create a motion 'behaviour' that you can tweak. This is the code for doing that in 2D :
var clip:DisplayObject = target as DisplayObject;
var angle:Number = Math.atan2(_point.y - clip.y, _point.x - clip.x) * HypeMath.R2D;
var deltaAngle:Number = HypeMath.getDegreeDistance(clip.rotation, angle);
clip.rotation += deltaAngle * _turnEase + (Math.random() * _twitch * 2) - _twitch;
clip.x += Math.cos(clip.rotation * HypeMath.D2R) * _speed;
clip.y += Math.sin(clip.rotation * HypeMath.D2R) * _speed;
... what I'd like to do is mimic this by introducing the Z. I guess I need to work out the angle to the target point and then set the object off on an orbit from its current location to the new target.
My math is pretty poor. Any help or pointers would be appreciated.

Subject: [Papervision3D] diff Viewport3D and BitmapViewport3D
hi all,
i'm about to start a little pv3d project that's needs anaglyphs, so i
want to use
the BitmapViewport3D.
Before i start i was wondering if there are any mentionable diffs between these
two... interactivity seems to work on both, but is there anything else
that maybe
doesn't work with the BitmapViewport?
thanks: lars

Hey Lee,
I've just checked out your experiments site and noticed you're doing some audio visualizations with PV. Cool! Me to, when i get time...
I've actually started to create a bit of a framework for audio visuals including PV and might be able to help you make your animations a lot more responsive across all frequencies bands.
Here's some of my older experiments pre framework - for inspiration!

If you want to chat about this or perhaps do some work together drop me a mail.
Nice work

Lee,
The graphics are stunning.

Can someone give me an example of the math I need to get an object to move in an orbit towards another point in 3D space. I think it has something to do with Quaternions. I want the object to point towards the target as well.
Thanks, Lee.
