hi, im working on a project at the moment with papervision 1.7b
im running MovieScene3D with a few Planes scattered randomly all facing the camera. i would like to add movie clips over the 3D scene based on the coordinates of the planes. more precisely, i need to convert 3D coordinates into 2D coordinates on the screen. if anyone has done this before or has any idea on how it can be done, can you please point me in the right direction. cheers. julaps _______________________________________________ Papervision3D mailing list Papervision3D@... http://osflash.org/mailman/listinfo/papervision3d_osflash.org |

in dod3d you have:
public var screen :Number3D = new Number3D(); ... private function calculateScreenCoords( camera :CameraObject3D ):void { var persp:Number = (camera.focus * camera.zoom) / (camera.focus + view.n34); screen.x = view.n14 * persp; screen.y = view.n24 * persp; screen.z = view.n34; } perhaps simply changing calculateScreenCoords( to public would help.

Thanks for your help.
I found another solution shortly after posting by going back through the papervision emails. public function getObj2DCords ( o:DisplayObject3D, camera:CameraObject3D, offsetX:Number = 0, offsetY:Number = 0 ):Point { var view:Matrix3D = o.view; var persp:Number = (camera.focus * camera.zoom) / (camera.focus + view.n34); return new Point ( (view.n14 * persp) + offsetX, (view.n24 * persp) + offsetY ); } seems to do the trick nicely.

Shorthand for DisplayObject3D. Everything visible in a Papervision scene extends the DisplayObject3D class.
