Hi all. I wanted to get the experts' opinions on the best way to accomplish what I need to do. I have a 3D object (a boat) that is in a view with the camera set to a position and roll (45) to try and achieve a "simcity" look. The settings are like this:
view.camera.x = 675; view.camera.y = -675; view.camera.z = -1300; view.camera.roll(45); view.camera.lookAt(new Number3D(0, 0, 0)); What I want to do is to move this object based on 2D points located on the stage (for example, a path along a river). What is the best way to do this? I did try converting 2D points to 3D by trying to get the intersect of a ray off a plane but it doesn't seem to work. Not sure if it is because I have a camera roll... I tried this based on some other posts (where my 2D point is the var pt): var plane:Plane3D = new Plane3D(); plane.fromNormalAndPoint(new Number3D(0, 1, 0), new Number3D(0, 0, 0)); var cameraPosition:Number3D = new Number3D(view.camera.x, view.camera.y, view.camera.z); var ray:Number3D = view.camera.unproject(pt.x, pt.y); ray.add(ray, cameraPosition); var intersect:Number3D = plane.getIntersectionLineNumbers(cameraPosition, ray); But, intersect.x does not seem to align with pt.x on the screen. Perhaps I am misinterpreting how this should work? Should I try to orient the stage (Flash CS4) the same way or can I leave that "flat" and translate 2D coordinates to the 3D space? Anyway, thanks for any guidance!
