Flash Player 10 3D settings with AS3/Flex – taterboy

Flash Player 10’s 3D capabilities are pretty light, but they have opened up many possibilities in UI design. Getting the perspective just right will take some tweaks, so here’s a demo to show some of the inner workings, like focal length and field of view.

Using the PerspectiveProjection class is the key to getting 3D in Flash looking just right, it is also very easy to use.

^?View Code ACTIONSCRIPT

//new PerspectiveProjection
var pers:PerspectiveProjection = new PerspectiveProjection();
 
//set the field of view - doesn't really do much
pers.fieldOfView = 55;//Default: 55, Range: 1 - 180
 
//set the focal length
pers.focalLength = 663;//Default: 663
 
//get stage center for a straight view, if you want a straight view.				
var centerX:Number = stage.stageWidth * 0.5;
var centerY:Number = stage.stageHeight * 0.5;
 
//set the projection center
pers.projectionCenter = new Point(centerX, centerY);
 
//assign to root/stage
//root.transform.perspectiveProjection = pers;
 
//assign to target/DisplayObject
triImage.transform.perspectiveProjection = pers;
