Good day, I am game developer, I installed demo in my app and also in standard OpenGL Xcode template for game.

But I can’t understand is working or not.
I see in log:
2015-12-10 16:50:49.874 TimeOfSilens[16920:5911307] Metal GPU Frame Capture Enabled
2015-12-10 16:50:49.874 TimeOfSilens[16920:5911307] Metal API Validation Enabled
[mgl-info] OpenGL functionality using Metal provided by MetalGL 0.10.0 (build 1) using 64-bit build.

But “Capture GPU frame” is disabled, and render scene without watermark, so I think Metal isn’t working. I even can’t see fps
(I am using Xcode 7.1.1 and testing apps on iPhone6 Plus)

Make sure all of the app code has access to the MetalGL headers, and that you are not using pre-compiled code that can’t see the headers, like GLKit or SpriteKit components.

You can use GLKView, but follow the instructions in the *EAGL and GLKit System Classes* section of the README-UserGuide.md document.

Bill,
Thanks for answer. I found why it not work. I used wrong path to MetalGL/RedirectHeaders/include folder
But I have trouble with glMapBufferRangeEXT() function.
Is I understand your library not supported it.

And I have question, what your library requirements for vertex format?

@Thufir

What do you mean by “requirements for vertex format”?

What do you mean by “requirements for vertex format”?

For example in our game we use this for keep vertex in buffer:

struct CUSTOMVERTEX
{
float[3] v; //vertex
float[3] vn; //normals
uint32_t color; // The vertex color
float tu, tv; //texture coordinates
};

This good for MetalGL, or it need change for best performances?

[Bill Hollings]

@Thufir

Yes, as with OpenGL ES, MetalGL supports interleaved vertices.
