DirectXShaderCompiler VS LearnOpenGL

> We may support DXBC generation in Clang in the future (we mentioned that in the original proposal to LLVM). That work is unlikely to begin for a few years as our focus will be on supporting DXIL and SPIR-V generation first.

I appreciate this quote[0] from the microsoft camp. Setting clear expectations that something will not be done is a nice bit of fresh air.

There's no need for transpilers these days, you can just compile HLSL to SPIR-V bytecode with dxc.

https://github.com/microsoft/DirectXShaderCompiler

Use DXC and only HLSL for your main shader editing.

You can see libdxilconv in there, DXIL is the DirectX Intermediate Representation, documented in the open source shader compiler from Microsoft.

BTW, this problem can be reproduced as described below: - clone https://github.com/SaschaWillems/Vulkan.git - build the project and run it with arguments : -v - s hlsl to enable the validation layer and to use hlsl code - run ComputeShader project. The following validation error "Type mismatch on descriptor slot ..." will be shown in the console. - to fix it, as suggested above, you can replace the 3rd line of emboss.comp, sharpen.comp, and edgedetect.comp from: Texture2D inputImage : register(t0); //Creates validation errors to RWTexture2D inputImage : register(u0); //no validation errors (you'll then need to recompile the shaders to spv with a proper hlsl compiler such as Microsoft dxc)

EDIT: There is also naga but it does not take HLSL as input: https://github.com/gfx-rs/naga but you can use DirectXShaderCompiler to compile to SpirV, then use naga to compile to Metal.

🤨 For a "refusal to acknowledge it", they do appear to have a rather sizeable document mapping between HLSL and SPIR-V? https://github.com/microsoft/DirectXShaderCompiler/blob/main/docs/SPIR-V.rst

I am starting work on a compute-driven rendering engine, and it seems that the best way to go around it will be to write code in HSSL, and then use DirectXShaderCompiler to generate SPIR-V, and SPIRV-Cross to then generate MSL. And while DXSC's repo has a page on incompatibilities, no such resource seems to exist for SPIRV-Cross targeting Metal.

I want to begin game development as a hobby, but I'm unsure where to start. I did follow through https://learnopengl.com/ a few years ago, and while it was a very interesting experience, I imagine I would need to use an existing engine to be productive.

Do you recommend any books and tutorials aimed at experienced programmers with 0 knowledge of game development/design?

- Game development - Unity3D project based learning in C#: https://learn.unity.com/ - Graphics - There was another user on r/GraphicsProgramming the other day (who teaches Computer Graphics at his university) that linked their lecture series for the entry year of their course here: https://tamats.com/learn/realtime-graphics/ - Project based learning: https://github.com/ssloy/tinyrenderer/wiki - Rendering API tutorials: https://vulkan-tutorial.com/, https://learnopengl.com/

If u want to make 3D game, you'll probably want to learn some 3D shader graphic stuff. OpenGL is a good start. https://learnopengl.com

LearnOpenGl.com

Possibly a smidge outdated.

Goes from blank window to rendering 3d meshes with advanced lighting techniques (HDR, SSAO and more).

Heped me understand shader pipeline, so I recommend it.

I'm reading the guest article about frustum culling on learnopengl.com and there's a video demonstrating how it works and for debug purposes they have a bunch of spheres turning red or green which I assume means they're being culled or not so my question is if I wanted to do this do I have to make a mesh for whatever bounding volume shape or is there a specific method for something like this?
