About you.Немного о вас.

The problem.Суть проблемы.

Available Stage3D powered frameworks.Движки работающие на основе Stage3D.

3D Engines. Alternativa3D-free,binary distribution. Flare3D-commercial,binary distribution. Away3D-free,open source. Yogurt3D-free,open source. Noob3D-commercial,binary distribution. Proscenium-free,open source by Adobe. Minko-free,open source. ND3D-free,open source. And some more…

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

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

3D Engines: Which is the best?Какой движок самый лучший?

None!Не один из них!

Each one wins or looses in one or more of these categories:Каждый из них проигрывает в одной или более следующих категориях: Performance.(Производительность.) Features. (Функциональность) Learning Curve.(Сложность изучения) Productiveness.(Продуктивность) Customization.(Специальные настройки) Support. (Техническая поддержка) Costs.(Затраты)

Performance.Производительность.

Features.Функциональность.

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

Learning Curve.Сложность изучения.

Mastering a Flash 3D engine. Осваиваем 3D движок. 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.

Productiveness.Продуктивность.

Flare3D. “Flare3D Studio” (World editor IDE). FLSL –GLSL like shader coding,AGAL free. “For Dummies” like API.

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

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

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

Code Modularity. Компактный код . 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); }}

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

Customization.Специальные настройки.

 Open Source is the winner!  Flare3D loans engine’s source code for payment.  Alternativa3D -?Kinect demo

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);

Technical Support.Техническая поддержка.

 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.

Costs.Затраты.

Some “out-of-the-Flash” thoughts.Размышление о других направлениях.

Conclusion.Подведем итоги.

Away3D = Features .(Функциональность)Alternativa3D = Industrial Quality.(Высокое качество)Flare3D = Ease of Use.( Удобство эксплуатации)

But what really matters …Но самое главное - это...

Determination to make a great game! Желание создать лучшую игру!

Thank you!Спасибо большое!
