Upgrade NME and Haxe3

After alias nme
sudo haxelib run nme setup

Got this error:
Called from native/media/SoundChannel.hx line 138

Called from native/Loader.hx line 63

Uncaught exception - load.c(357) : Primitive not found : /usr/lib/haxe/lib/nmedev/3,6,0//ndll/Mac/nme@nme_sound_channel_set_position(2)

You need to rebuild native library to fixed it.
sudo haxelib run nme rebuild mac

Stage3D: 2D Particle Random Motion [optimized]

I just updated some code of my last demo and optimized it by reducing draw calls.
Now it can render over large number of particle(500,000+).

Here are some optimization:

• reduce draw call
• upload minimum of constants

Try it!!

Stage3D Limitation and Optimization

Stage3D AGAL Limitation:

• The VertexBuffer is limited to 65535 vertex.
• The IndexBuffer is limited to 983040 index.
• In theory, you could have up to 983040/3 = 327680 triangle in one draw call.
• In particle(using quads), you could have up to 65535/4 = 16383 particle max per draw call.
• Shaders length can only contain a maximum of 200 opcodes.
• The drawTriangles limited to 32768 calls per present call.

Optimization:

• reduce draw call.
• reuse material and batch rendering.
• upload minimum number of constants.
