4. About you. .

5. The problem. .

6. Available Stage3D powered frameworks. Stage3D.

8. 2D Engines ND2D-free,open source. Starling Framework-free , open source. M2D(Discontinued?)-free , open source.

9. Particle Engines FLINT Particles-robust particle engine .Free, open source. ND2D basic particles system.Free,open source. Starling-basic particles system.Free,open source. Flint demo

10. 3D Engines: Which is the best? ?

11. None! !

12. Each one wins or looses in one or more of these categories: : Performance.(.) Features. () Learning Curve.( ) Productiveness.() Customization.( ) Support. ( ) Costs.()

13. Performance..

16. Features..

17. Basic system modules in a typical 3D engine: External assets handling. Lightning system. Rendering system. Materials library & composing tools. Primitives library. Physics, AI, Particle engines. Network. GUI

23. Learning Curve. .

24. Mastering a Flash 3D engine. 3D . The APIs follow the same basic 3D engine paradigm. Experience with the previous versions helps a lot. Previous game development and Math experience contribute to the learning process.

25. Productiveness..

26. Flare3D. Flare3D Studio (World editor IDE). FLSL GLSL like shader coding,AGAL free. For Dummies like API.

27. Flare3D Studio IDE Character model by courtesy of Roman Zinchenko http://www.wix.com/zinche/zraFlare Studio demo

28. Flare3D Shading Language FLSL =AGAL Abstraction. GLSL/CG look.

29. OpenGL 3.3 GLSL Flare3D V2 FLSL #version 330 layout(location = 0) in vec4 position; layout(location = 1) in vec4 color; < namespace:"flare", name:"TextureFilter" > smooth out vec4 theColor; uniform vec3 offset; public texture "texture"; uniform mat4 perspectiveMatrix; public float1 alpha = 1; input UV0 uv0; void main() interpolated float4 iUV; { vec4 cameraPos = position + vec4(offset.x, offset.y, offset.z, 0.0); private void vertex0() gl_Position = perspectiveMatrix * cameraPos; { theColor = color; iUV = uv0; } } private float4 fragmentTexture0() { return sample( "texture", iUV.xy, "2d,repeat,linear,miplinear" ) * alpha; } #version 330 smooth in vec4 theColor; technique main" { out vec4 outputColor; vertex vertex0(); fragment fragmentTexture0(); void main() } { outputColor = theColor; }FLSL Demos

30. Code Modularity. . Alternativa3D vs Flare3D Skin Animation set up code samplesprivate function loadModel():void{ private function loadModel():void{ var loaderCollada:URLLoader = new URLLoader(); model = scene.addChildFromFile( loaderCollada.dataFormat = "assets/spyAnim.f3d,scene);URLLoaderDataFormat.TEXT; scene.addEventListener( Scene3D.COMPLETE_EVENT, loaderCollada.load(new completeEvent );URLRequest("assets/SpyAnimCollada.DAE")); } loaderCollada.addEventListener(Event.COMPLETE, private function completeEvent(e:Event):voidonColladaLoad); {} scene.resume(); model.play();private function onColladaLoad(e:Event):void { } var parser:ParserCollada = new ParserCollada(); parser.parse(XML((e.target as URLLoader).data),"assets/"); var mesh:Skin = parser.getObjectByName("spy") asSkin; mesh.y =0; container.addChild(mesh); var animSwtich:AnimationSwitcher=newAnimationSwitcher(); var animClip:AnimationClip=parser.animations[0]; var animAll:AnimationClip=animClip.slice(0,870/30); animContr=new AnimationController(); animContr.root=animSwtich; for each (var resource:Resource inscene.getResources(true)) { resource.upload(stage3D.context3D); }}

31. Away3D. Compact API ,but not like Flare3D. Prefab3D- Visual IDE V2 .still under development. Away3D 3x users benefit from smooth portability.

32. Customization. .

33. Open Source is the winner! Flare3D loans engines source code for payment. Alternativa3D -?Kinect demo

34. Away3D core adjustments example 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);

35. Technical Support. .

36. Away3D has much larger community and learning materials like books and tutorials , than others. Four books dedicated to Away3D development. Away3D and Flare3D-both supply professional support for payment.

37. Costs..

38. Some out-of-the-Flash thoughts. .

39. Conclusion. .

40. Away3D = Features .()Alternativa3D = Industrial Quality.( )Flare3D = Ease of Use.( )

41. But what really matters - ...

42. Determination to make a great game! !

43. Thank you! !
