camera.orbit issue.

[Hanpan]

Hi,

I've just download the latest version of PV2.0 and there seems to be a lot of changes to cameras.

What I am trying to do is create a really simple camera orbit, exactly like this:
http://www.whitevoid.com/application.html

I have tried using camera.orbit and a variety of different mouseXY algorithyms but I can't seem to get anything that resembles that simple "wobble" effect. My planes, viewports are all setup basically so I know its something I am doing with the camera.

Any help appreciates!

[Helmut Granda-2]

Look at the sample files.... there are some similar exercises in there.

Please excuse my ignorance... I looked through the GW example files but couldn't find anything like this... is there someplace in particular I should be looking?

hello.
Actually i think the whitevoid should have a better camera movemente.
so, i did it.
here the planes "look" at he mouse, instead of turning their backs into mouse. lol
sorry my english sucks.

In the render function you should have something like this

addEventListener(Event.ENTER_FRAME, loop);
function loop(e:Event):void {

        var rotY: Number = (mouseY-(stage.stageHeight/2))/(stage.height/2)*(300);
        var rotX: Number = (mouseX-(stage.stageWidth/2))/(stage.width/2)*(-300);
        camera.x= camera.x+(rotX-camera.x)/5;
        camera.y= camera.y+(rotY-camera.y)/5;
       
        renderer.renderScene(scene, camera, viewport);
}

what are u doing? the 1st part of the script(2 lines) you are setting how much distance your planes would have, and where they should turn. try changing the 300 to some other value.
and finally the last 2 lines of code are move the camera, and setting a delay time or a tweener effect. change the value 5 for different speeds.

I think thats all.
u can see a experiment here with this script running:

Hi,

Thanks very much for the reply.

For some reason, my example just pans the camera around and my planes don't rotate. Do I need to set the camera to lookAt a particular target? What are you camera settings?

Also, is this example using the Great White trunk or 1.5?

Thanks!

Hi,

Thanks for the code sample, it was very enlightening. It appears that the camera3D class has been updated with the latest build of GW making this method act kind of strangely. At least I know it's nothing I am doing wrong though!

Ok, with a LOT of playing about I finally managed to solve this (kinda).

var rotX:Number = (_stage.stage.mouseX-(_stage.stage.stageWidth / 2))*(0.05)-90;
var rotY:Number = (_stage.stage.mouseY-(_stage.stage.stageHeight / 2))*(0.05)+90;
camera.orbit(rotY, rotX);

The important thing to note is that you need to add +/-90 (degrees) onto the rotation figures in order to get the camera to face the stage directly.

Opps sorry gordee I forgot to take that out of my code... _stage is just my stage reference, you can just remove that :)

Following up on this, I managed to get the same functionality out of the following code:

var rotX:Number = (stage.mouseX-(stage.stageWidth / 2))*(0.5);
var rotY:Number = (stage.mouseY-(stage.stageHeight / 2))*(0.5);
       
camera.x = rotX;
camera.y = rotY;

camera.lookAt(container);

camera.lookAt(container) MUST be inside the enterFrame or for some reason the camera just pans rather than rotates. Can someone shed some light onto why this has changed?

Cool,
 
thanks for sharing!
 
Got any rendering advice? I'm applying a bitmap to a sphere (a spherical photograph) and then trying to fly the camera round it, or at least halfway round. Its really eating into my processing power!
