The third feature of WebGPU is called the binding model, which largely
\nresembles the resource grouping mechanisms present in Vulkan.
\nTo group resources in WebGPU, a GPUBindGroup object is provided, which can be linked with other similar objects during command recording for use in shaders. Creating such groups allows the driver to perform necessary preparatory actions in advance and significantly speeds up the browser's ability to change resource bindings between render calls. The layout of resource bindings can be predefined using the GPUBindGroupLayout object.<\/p>\n
