It contains two projects, WPF and WinUI3, which use OpenGL and DirectX rendering respectively. 19 | - The rendering mode relies on the rendering ideas provided by OpenTK and uses the NV_DX_Interop extension to implement interaction between DirectX and OpenGL. 20 | - Using this rendering method can greatly improve the graphics performance of WPF and WinUI3, and can also access different graphics libraries. 21 | 22 | ### 项目结构 23 | - RenderContext：渲染上下文，用户管理 OpenGL 和 DirectX 的渲染环境。 24 | - Framebuffer：帧缓冲，用户管理 OpenGL 和 DirectX 的帧缓冲。 25 | - GameControl：渲染控件，管理上下文和渲染。 26 | 27 | ### Project Structure 28 | - RenderContext: Rendering context, user management OpenGL and DirectX rendering environment. 29 | - Framebuffer: Frame buffer, user management OpenGL and DirectX frame buffer. 30 | - GameControl: Rendering control, management context and rendering. 31 | 32 | ![image](https://github.com/qian-o/SilkRenderer/assets/84434846/fbc9e032-cfcb-453c-a3de-da8f88d78c3a) 33 | 34 | ![image](https://github.com/qian-o/SilkRenderer/assets/84434846/43046f40-f496-4258-ba0f-7c0d437ab2b9) 35 | -------------------------------------------------------------------------------- /SilkRenderer.WPF/App.xaml: -------------------------------------------------------------------------------- 1 |  6 | 7 | 8 | 9 | 10 | -------------------------------------------------------------------------------- /SilkRenderer.WPF/App.xaml.cs: -------------------------------------------------------------------------------- 1 | using System.Windows;
