Re: Can't seem to figure out Cameras

Its mostly done for you :-)
A simple way to circle around your object is

onLoop(){

camera.position = new Number3D(0, 0, 0);  // your 'circle center'
camera.yaw(1); // your rotation speed around Yaxis
camera.moveBackward(1000); // move camera back 1000 units with its current rotationY

render()
}


try to implement the hoverCamera/ orbit. Its much more fun :-)

Hi there,

I'm loading a Collada object and using a BitmapFileMaterial to give it texture from a png file. The Collada object loads on x:0, y:0, z:0.

The thing is that I want to have my camera circle the object all the time just to see the object better and from all angles.

I can't figure out how to position the camera in a logical way, I just try and change the camera x, y and z to fit my needs...

Does anyone know a good tutorial or example on camera positions? I suppose the size of the Collada object will be important, how do I take that into account?

Thanks a lot, next step after understanding this will be to apply this http://pv3d.org/2008/11/19/dragging-mouse-for-camera-orbit/ to my scene...

Thanks,

Javier
