They reference resources such as textures and other buffers. I'll talk about four specific enhancements in Metal 3 that you may find useful for bindless rendering.Īrgument buffers are the fundamental Metal construct that allows you to link your resources together. Even better, when bindless rendering is paired with other Metal features like Heaps, apps and games enjoy better performance, thanks to less pressure on the CPU. The app makes the 3D models and textures, including the floor, the trucks, their materials, and even the sky, available to the ray tracing shaders by placing all its data into argument buffers. After the app goes bindless, the ray tracing shaders can access all the data they need to beautifully shade the reflections. This lets you bind a single buffer that your shaders can freely navigate and access the resources they need to calculate elaborate surfaces and lighting. Unlike the traditional binding model, where you bind each resource independently to a specific slot in a pipeline, in the bindless model, resources are first linked together in memory. In this example, an array aggregates all the meshes in a scene. Conceptually, this is what this looks like. In the bindless model, resources are aggregated and linked together with argument buffers. Then I'll hand it over to Mayur, and he’ll show you how the tools can help you adopt a bindless model. I'll give you two specific tips today to improve your CPU and GPU times. For today, I'll start with a brief recap of how the bindless binding model works, and how you can easily adopt bindless in your games and apps with Metal 3.īindless rendering aggregates data, which opens up new opportunities to improve performance on the CPU and GPU. The bindless binding model is a modern way to provide resources to your shaders, unlocking advanced rendering techniques, such as ray tracing. Alè: In this session we are going to talk about bindless rendering. And I’m Mayur, also from the GPU Software team. My name is Alè Segovia Azapian from the GPU Software team here at Apple. ♪ instrumental hip hop music ♪ Hello and welcome.
