the Webar project and requires real-time tracking of the user's camera to process the video stream (256*256), which is very significant using the GPU, otherwise the real-time tracking cannot be achieved.Third, how to achieve universal GPU computing?3.1, first, we pass a flowchart, demonstrating the principle:3.2.

If you are not familiar with sharpgl, you can search for sharpgl at www.codeproject.com. In a small example, we can load various images to a spherical planet to show that the planet is automatically rotated. We can use wsad and

shader.Compiling linksThe GPU does not directly understand the GLSL language, we need to compile the shader source code and link to the shader program for use by the GPU. Conveniently, we can call JavaScript API in the browser to complete the work of compiling links.PersonallyNow it's time to do the actual combat. We read the code and explain the details.Let's look at our HTML structure first:Because JavaScript does not directly support the operation of matrices and vectors, we refer to the

Chromium Graphics: Principle and Implementation of the synchronization mechanism between GPU clients-Part I, chromium-part Abstract: The GPU process architecture in Chromium allows multiple GPU clients to access the GPU service at the same time, and there may be data dependencies between GPU clients, therefore, a synchronization mechanism must be provided to ensure the order of GPU operations. This article discusses the synchronization between GPU clients in a multi-process architecture and the
