Odin now officially supports both the Metal API and Direct3D 11 & 12 out-of-the box! This makes Odin currently the only language that officially supports all of the major graphics APIs: OpenGL, Vulkan, Direct3D11, Direct3D12, Metal, and WebGL 1 & 2.

Metal #

Odin now has NATIVE Metal support, and it is even cleaner than writing it in Objective-C in numerous cases!

Native support means that Odin is directly caling the Objective-C runtime, and not through a wrapper of another language. This means that the Metal package in Odin will have virtually the same performance as Objective-C code. This means you can now write Metal code without being locked into using an Apple-specific language.

Example and Documentation #

You can check out a minimal demonstration of Metal in Odin here: https://gist.github.com/gingerBill/e1270f60a1739c266934599c2bee46f5.

And the automatically generated package documentation here: package vendor:darwin/Metal documentation.

Metal in Native Odin!!! No need for Objective-C or Swift any more it seems.https://t.co/v5D2FP1LlB (I had to do the obligatory RGB triangle)

This means that Odin will ship out of the box with Metal, Vulkan, and OpenGL, and libraries such as GLFW and SDL!

Metal in Objective-C #

MTLSamplerDescriptor *samplerDescriptor = [[MTLSamplerDescriptor alloc] init];

[samplerDescriptor setSAddressMode: MTLSamplerAddressModeRepeat];
[samplerDescriptor setTAddressMode: MTLSamplerAddressModeRepeat];
[samplerDescriptor setRAddressMode: MTLSamplerAddressModeRepeat];
[samplerDescriptor setMagFilter: MTLSamplerMinMagFilterLinear];
[samplerDescriptor setMinFilter: MTLSamplerMinMagFilterLinear];
[samplerDescriptor setMipFilter: MTLSamplerMipFilterLinear];
[samplerDescriptor setSupportArgumentBuffers: YES];

id< MTLSamplerState > samplerState = [device newSamplerStateWithDescriptor:samplerDescriptor];

[samplerDescriptor release];

// ...

[samplerState release];

Metal in Odin #

samplerDescriptor := MTL.SamplerDescriptor.alloc()->init()

samplerDescriptor->setSAddressMode(.Repeat)
samplerDescriptor->setTAddressMode(.Repeat)
samplerDescriptor->setRAddressMode(.Repeat)
samplerDescriptor->setMagFilter(.Linear)
samplerDescriptor->setMinFilter(.Linear)
samplerDescriptor->setMipFilter(.Linear)
samplerDescriptor->setSupportArgumentBuffers(true)

samplerState := device->newSamplerState(samplerDescriptor)

samplerDescriptor->release()

// ...

samplerState->release()

Example and Documentation #

You can check out a minimal demonstration of Direct3D11 in Odin here: https://gist.github.com/gingerBill/b7b75772f92c5511a9cd3ca2e28eca37.

And the automatically generated package documentation here for both D3D11 and D3D12:

• package vendor:directx/d3d11 documentation
• package vendor:directx/d3d12 documentation

I got Metal working natively in @odinlang the other day. I've now gone and got D3D11 and D3D12 working in Odin!https://t.co/cHzyfmeBLG

Writing Direct3D code is Odin is really simple! The code will be nearly the same as writing it as if you were using the APIs in native C++ with thanks to the -> operator:

depth_buffer_desc: D3D11.TEXTURE2D_DESC
framebuffer->GetDesc(&depth_buffer_desc)
depth_buffer_desc.Format = .D24_UNORM_S8_UINT
depth_buffer_desc.BindFlags = .DEPTH_STENCIL

depth_buffer: ^D3D11.ITexture2D
device->CreateTexture2D(&depth_buffer_desc, nil, &depth_buffer)

depth_buffer_view: ^D3D11.IDepthStencilView
device->CreateDepthStencilView(depth_buffer, nil, &depth_buffer_view)

sampler_desc := D3D11.SAMPLER_DESC{
	Filter         = .MIN_MAG_MIP_POINT,
	AddressU       = .WRAP,
	AddressV       = .WRAP,
	AddressW       = .WRAP,
	ComparisonFunc = .NEVER,
}
sampler_state: ^D3D11.ISamplerState
device->CreateSamplerState(&sampler_desc, &sampler_state)
