Вам заказали разработку инновационной 3d game на Flash? Требования более, чем высокие, а сроки поджимают? Нет времени отладить собственный 3D движок, и встала проблема выбора наиболее подходящего из уже существующих, предлагающим самый широкий инструментарий? Как узнать, какой из стандартных 3D движков лучше всего подходит для данного проекта? В своем докладе Михаил даст ответ на эти и многие другие вопросы. Он остановится на движках Away3D и Flare3D с Alternaiva3D в качестве почетного гостя конкурса. Будут рассмотрены важнейшие достоинства и недостатки обсуждаемых движков, чтобы сориентировать разработчиков в выборе подходящих инструментов и обеспечить успех выпускаемым 3D продуктам.

Vector3D to screen fix:
Adding code to lens:
public function projectToScreenSpace(point3d:Vector3D,screenW:Number,screenH:Number):Point{
var p:Point=new Point();
var v:Vector3D=matrix.transformVector(point3d);
p.x=((v.x*screenW)/(2*v.w))+screenW*0.5;
p.y=(-(v.y*screenH)/(2*v.w))+screenH*0.5;
return p;
}
Adding code to Camera3D:
public function projectToScreen(point3d : Vector3D,screenW:Number,screenH:Number) : Point
{
return lens.projectToScreenSpace(inverseSceneTransform.transformVector(point3d),screenW,screenH);
}
Using:
var screenPoint:Point=_view.camera.projectToScreen(sp.position,_view.width,_view.height);
