4. 3D. Everywhere.
Deliver engaging, interactive and rich 3D content and applications on
desktops, mobiles and the web.

5. Focus on design. Boost with code.
Minko « Studio » Edition
Designers integrate 3D content, customize materials, setup lights and animations.
Developers plug in scripts and interactivity.

6. The sky is the limit.
Minko « Community » Edition
Build desktop, web and mobile 3D applications with
Minko’s free and open source SDK including
a fully-featured 3D engine and plugins.

7. IronForce (EA/Coolfish)

8. « We chose Minko to be the 3D engine in one of our new Flash-based
games because we think it’s a highly professional solution in terms of
development ecosystem and high performance. »
André Weissflog, Head of Development at BigPoint

9. Features
§ 100% compatible with Windows, Mac,
Linux, iOS, Android and WebGL
§ WYSIWYG Scene editor
§ 3D scene graph API
§ 80+ 2D/3D file formats supported
§ Dynamic assets loading
§ Über-shaders
§ Components & scripts system
§ 3D compression, simplification and
streaming
§ Physics (Bullet)
§ Plugin system (Oculus, Leap, ….)
§ Data-driven rendering engine
§ Particles engine

10. Why C++?
§ Performances
§ You can’t beat C++ and its static optimizations
§ Integration
§ It’s the common standard for big projects
§ Expressiveness
§ C++11 lambdas, type inference, memory management
§ Cross-platform
§ Windows, Mac, Linux, iOS, Android, Flash, Windows Phone, HTML5

11. Emscripten https://github.com/kripken/emscripten
§ Atwood’s Law
– « Anything that can be done with JavaScript will be done in JavaScript »
§ Open source project driven by Mozilla
– Based on LLVM, which is supported by Google, Apple, Intel and many more
§ Cross-compile C++ code to Javascript code
– Binds OpenGL to WebGL
– Provide virtual file system
– C++ ó JavaScript bindings
§ Code optimizations
–
–
–
–
LLVM and C++ specific optimizations
Closure compiler
asm.js (2x performances of native code!)
LZMA compression

EXAMPLE: SPONZA HTML5!

14. Conclusion

15. My Feedback – The Good Parts
§ Working with C++ 2011 is amazing
§ More complex but so much powerful/expressive than AS3/JS
§ Useful and reliable STL containers (list, maps, sets, etc…)
§ Shared pointers make memory management just as easy as with
managed languages: not a single memory leak so far!
§ Visual Studio/Xcode/Eclipse are very good IDEs
§ Minko 3 is much lighter and yet just as much powerful
§ Vagrant + Premake: efficient cross-compilation build

16. My Feedback – The Good Parts
§ Compatibility
§ The app runs on Windows, Mac, Linux, iOS, Android and WebGL
without a single modification!
§ Targeting Android was just a 2-day job
§ Speed
§ Native speed on Windows, Mac, Linux, iOS and Android
§ 2x speed of native code in HTML5/WebGL thanks to asm.js!
