 # RHI 渲染模块设计文档
 ## 1. 项目背景
-本项目旨在参考 Unity 渲染架构，为已有的 **OpenGL** 、**Direct3D 12** 和 **Vulkan** 图形 API 后端设计统一的**渲染硬件抽象层（RHI）**，屏蔽 API 差异，实现引擎上层逻辑与底层图形 API 的解耦。需要注意的是，该模块的抽象层主要面向**Direct3D 12** 和 **Vulkan**这些高级图形API的显示设计。

 ## 2. 核心设计理念
 **求同存异，分层抽象，特性降级，底层逃逸**

 - **特性降级**：对高级特性提供能力检测和替代方案
 - **底层逃逸**：允许直接访问原生 API 以满足极端需求
 
+## 3.核心约束原则
+该RHI模块的抽象层主要面向**Direct3D 12** 和 **Vulkan**这些高级图形API的显示设计。
+该RHI模块主要参考Unity引擎的底层RHI模块，后面方便参考Unity的SRP做上层渲染管线。
