Cross-platform .NET 8 C# 12 game engine.

Hey! I am Amer Koleci, my github id is `amerkoleci`

I'm a self-taught, passionate software developer from Italy

• 🔭 I’m currently working as senior software engineer using C#/VB .NET and .NET in general writing WMS software.
• ❤️ I love open source and work on personal projects whether possible, I enjoy contributing to other projects and share opinions with other people.
• 🌟 I like to write game engine code and explore the different graphics APIs out there (Direct3D12, Vulkan, Metal or OpenGL). Therefore, I have created several projects to abstract the graphics APIs to make it easier to do graphics programming, which is where my main focus is. I love learning and read about new rendering techniques and try to implement them.

alimer's Issues

WebGPU support.

This is not really a feature request, just a suggestion. Instead of using DirectX/Vulkan/OpenGL you could use WebGPU. Why WebGPU? It's a performant crossplatform graphics API (doesn't only support web). I thought it might interest you so you don't have to write a backend for each graphics API.

Quick Question

When you were converting this project to .net 7 with AOT. did you encounter the following error? how did u fix it?

it's happening on the following line.

using var dxgiFactory = device.QueryInterface<IDXGIDevice>().GetParent<IDXGIAdapter>().GetParent<IDXGIFactory>();

Foundations to write a 2D GUI library

I'm currently using ImGui.Net with Vortice for the application I'm working one.
However, Dear ImGui has several imperfections/limitations that frustrate me.

I've wrote several 2D GUI libs in the past, on the top of a game engine and I would like to consider the effort needed to write one for Vortice.
Hopefully you can answer to some of them without me go digging in the source code (lazy of me, but I think it could worth a shot to discuss about this with you).

Text render
Do you have anything so far ? Especially toolkit to create SDF based texture of a font and then a shader that displays text using the SDF texture?

Draw call
How easy/hard would it be for me to generate draw lists with the common features needed for such project:

• GPU resource creations, how easy it is to create texture, Buffer, Shader, binding based resource, etc.
• Exposing Scissor / clipping region and other GPU states easily
• Texture, VS/PS Shader binding with old the basic features coming along with it
• Possibility to use a dedicated Z buffer and having the entry point to overlay the GUI over the whole 3D viewport

If all the foundations are exposed by Vortice, I could consider writing a GUI on the top of it. It certainly wouldnt be a 2022 thing but could definitely be a Q1 2023 one.
I have to assess how long it would take to create the thin layer on the top of the GPU stuffs in order for me to write the GUI on the top of it, encapsulating the complexity of the GPU rendering.

Nuget Support!

Hello i love your Lib and i would love to work with it!

Can you maybe upload it on Nuget?

Windows Universal Support? #37

Can you maybe add Support for Windows Universal Platform? (Xbox Support)

And i love your work!

PS: Do you have a Discord?

Input
