RHI Guide

Use this guide to learn the Zenith.NET programming model. It covers the C# objects and workflows used to create resources, record GPU work, and present results.

Fundamentals

Start here if you are new to Zenith.NET:

1. Runtime introduces the graphics context, capabilities, queues, and object lifetime.
2. Commands shows how to record and submit work.
3. Synchronization explains barriers, texture transitions, and queue dependencies.
4. Shaders shows how to compile Slang entry points and create shader objects.
5. Bindless Resources shows how shaders access resources through handles.
6. Queries shows how to collect visibility results and measure GPU work.

Resources

• Heaps covers placed resources, allocation requirements, offsets, and lifetime.
• Buffers covers creation, data transfer, mapping, and views.
• Textures covers creation, views, uploads, layouts, resolves, and samplers.

Workloads

• Rasterization covers graphics pipelines, render passes, and draw commands.
• Compute covers compute pipelines and dispatch commands.
• Ray Tracing covers acceleration structures and inline ray queries.
• Mesh Shading covers mesh shading pipelines and dispatch commands.

Presentation

• Swap Chains shows how to render to a window and present a frame.
• Views shows how to render through supported .NET UI controls.
