Google chrome canary map10/30/2023 If this is not included, the supplied device will have a reasonable general-purpose spec that is good enough for most purposes. This method also accepts an options object (referred to as a descriptor), which can be used to specify the exact features and limits you want the logical device to have. A device can be requested via GPUAdapter.requestDevice().If this is not included, the device will provide access to the default adapter, which is good enough for most purposes. This method accepts an optional settings object allowing you to request for example a high-performance or low-energy adapter. You access an adapter via the GPU.requestAdapter() method.The Navigator.gpu property (or WorkerNavigator.gpu if you are using WebGPU functionality from inside a worker) returns the GPU object for the current context.Each web app needs to be able to access WebGPU in isolation for security and logic reasons.Ī logical device - represented by a GPUDevice object instance - is the basis from which a web app accesses all WebGPU functionality. A physical device's GPU is used by many applications and processes concurrently, including potentially many web apps. Logical devices are required to provide multiplexing capabilities. A logical device is an abstraction via which a single web app can access GPU capabilities in a compartmentalized way. A WebGPU adapter effectively represents a physical GPU and driver available on the underlying system, in your code. A browser's WebGPU implementation handles communicating with the GPU via a native GPU API driver.It is possible for a system to have multiple native OS APIs and drivers available to communicate with the GPU, although the above diagram assumes a device with only one native API/driver. API instructions are sent to the GPU (and responses received) via a driver. Metal on macOS), is a programming interface allowing native applications to use the capabilities of the GPU. A native GPU API, which is part of the OS (e.g.Note: The above diagram assumes a device with only one GPU. In addition, it can handle expensive computations such as culling and skinned model transformation directly on the GPU. Rendering of individual objects is significantly cheaper on the CPU side, and it supports modern GPU rendering features such as compute-based particles and post-processing filters like color effects, sharpening, and depth-of-field simulation. It supports graphic rendering, but also has first-class support for GPGPU computations. WebGPU addresses these issues, providing an updated general-purpose architecture compatible with modern GPU APIs, which feels more "webby". 3D graphics apps are becoming increasingly demanding, both in terms of the number of objects to be rendered simultaneously, and usage of new rendering features.GPGPU computations are becoming more and more important for many different use cases, for example those based on machine learning models. It does not handle general-purpose GPU (GPGPU) computations very well. WebGL is based wholly around the use case of drawing graphics and rendering them to a canvas.WebGPU on the other hand will have new features added to it going forwards. There are no more updates planned to OpenGL (and therefore WebGL), so it won't get any of these new features. Since WebGL's release, a new generation of native GPU APIs have appeared - the most popular being Microsoft's Direct3D 12, Apple's Metal, and The Khronos Group's Vulkan - which provide a multitude of new features.However, WebGL has some fundamental issues that needed addressing: Developers have used these tools to build immersive web-based 3D games, music videos, training and modeling tools, VR and AR experiences, and more. WebGL and the GLSL language used to write WebGL shader code are complex, so several WebGL libraries have been created to make WebGL apps easier to write: Popular examples include Three.js, Babylon.js, and Pla圜anvas. WebGL is a JavaScript port of the OpenGL ES 2.0 graphics library, allowing web pages to pass rendering computations directly to the device's GPU to be processed at very high speeds, and render the result inside a element. It is fair to say that WebGL revolutionized the web in terms of graphical capabilities after it first appeared around 2011.
