Hi Fei, Several years ago there was much discussion about which direction to take web graphics standards - either continue to extend WebGL toward OpenGL ES 3.1/3.2, or pursue the new family of low-level explicit graphics APIs (D3D12/Metal/Vulkan). After much investigation it was decided to leave the legacy behind and pursue a new standard, WebGPU. There is a tremendous amount of cross-industry momentum behind WebGPU; the first version, and implementations, will ship later this year.
I recommend you abandon the course of trying to get an OpenGL ES 3.1 JavaScript binding in Chromium, and instead see whether you can achieve what you want using the existing WebGPU implementation in Chromium, as well as Dawn, Chromium's native implementation of the API. https://gpuweb.github.io/gpuweb/ https://gpuweb.github.io/gpuweb/explainer/ https://dawn.googlesource.com/dawn/ Best, -Ken On Mon, May 9, 2022 at 5:02 AM 杨飞 <hyangf...@gmail.com> wrote: > Hi everyone. > > I've asked a similar question in chromium-dev, then I realized here might > be the better place to ask. > > I'm trying to hack Blink (in Chromium) to embed a native 3D rendering > engine behind Chromium.
