Introducing D3D12 Mesh Shaders

One of the new features added to D3D12 is the Mesh Shader, which replaces the existing Vertex Shader - Geometry Shader pipeline with a GPGPU-based Compute Shader.

Mesh Shaders can better leverage modern GPU hardware. They enable GPU-based view-frustum culling, and can even implement level-of-detail (LOD) and point-to-polygon scaling, both of which are typically performed with Geometry Shaders.

This lecture explains what a Mesh Shader is, how you can use it, and how to approach it when actually programming it.

1. Introduction to Shader Pipeline and Mesh Shader

page1

Modern graphics APIs are increasingly moving beyond the traditional vertex shader pipeline and toward general-purpose GPGPU technology. Mesh shaders are a first step in this direction. This article explains how the vertex shader pipeline can be transformed into a GPGPU-based mesh shader.

2. Benefits and Implementation of Mesh Shader

page2

Mesh Shaders can be helpful when handling large amounts of instancing. While using a Mesh Shader doesn't necessarily result in significantly improved graphics, it can offer performance benefits when achieving the same graphical quality. To implement such a Mesh Shader, resources must be divided into units called Meshlets. This section details how to create and process Meshlets.

            It seems the mainstream graphics API has shifted from D3D11 to D3D12. D3D12 supports attractive features but has a steep learning curve. However, I believe that with gradual learning, individuals can also create games using the D3D12 API. Therefore, based on my experience building a game directly with D3D12, I aim to provide the knowledge base needed to challenge D3D12 game programming.

            DirectX 12 supports real-time Raytracing, allowing high-quality graphics to be implemented with concise code. However, due to the high barrier to entry, programmers who directly utilize it are rare. Based on experience applying Raytracing to actual games, this course will help you develop your own Raytracing engine.
