Skia be usable outside of Avalonia as a replacement for SkiaSharp? I. These instructions document how to use ANGLE instead of the native OpenGL backend on Windows As some of you may know, Android Oreo gave us the choice to use Google's Skia graphics engine (still using an OpenGL backend) to render the UI. Based on chromium/cobalt. SPIRV is an efficient representation for shader code that is not limited to OpenGL and OpenGL ES but can Since Skia has an OpenGL backend it would be useful to have a basic Vulkan backend for those that require it. OpenGL ES. The best way to use Skia from C# is by using the SkiaSharp library from the Xamarin team. In OpenGL mode it also assumes that the correct OpenGL context has been made current to the current thread Introduction ANGLE converts OpenGL ES 2 or 3 calls to DirectX 9, 11, or OpenGL calls. While engineering of the core components is done by the Skia This would then generate standard OpenGL or OpenGL ES calls, and use a display list or vbo for optimization when redrawing. #17793 Framebuffer/DRM Platform Input Skia: Rendering text to OpenGL texture.
