一个基于 C++ 和 SDL2 的小型 CPU 渲染器练习项目。当前版本聚焦在最基础的 2D 光栅化能力上，通过 CPU 维护帧缓冲区，再将像素数据上传到 SDL 纹理并显示到窗口中。
|
一个基于 C++20 和 SDL2 的 CPU 软光栅化练习项目。
|
||||||
|
|
||||||
项目目标不是调用现成图形 API 去画三角形，而是从像素写入、直线绘制、三角形光栅化开始，逐步补齐一个软件渲染器所需的核心 pipeline。
|
这个仓库当前还处在早期阶段，重点不是调用现成图形 API 画三角形，而是自己维护帧缓冲、自己做基础光栅化，并逐步搭起一个小型 software renderer 的骨架。
|
||||||
|
|
||||||
## 项目定位
|
|
||||||
|
|
||||||
- 使用 CPU 完成像素级绘制和光栅化
|
|
||||||
- 使用 SDL2 负责窗口创建、纹理更新和屏幕展示
|
|
||||||
- 以最小可运行工程为基础，逐步扩展到 3D 渲染流程
|
|
||||||
|
|
||||||
## 当前状态
|
## 当前状态
|
||||||
|
|
||||||
当前代码已经具备这些基础能力：
|
目前已经完成或具备雏形的部分：
|
||||||
|
|
||||||
- 基于 `frameBuffer` 的软件像素输出
|
- 使用 SDL2 创建窗口、纹理和显示循环
|
||||||
- `SetPixel` 像素写入
|
- 在 CPU 侧维护 `FrameBuffer`
|
||||||
- Bresenham 直线绘制
|
- 像素写入接口 `set_pixel`
|
||||||
- 三角形线框绘制
|
- 基础直线光栅化模块 `Rasterizer`
|
||||||
- 三角形包围盒扫描填充
|
- 2D 三角形、包围盒、颜色等基础数据结构
|
||||||
- SDL2 窗口创建、纹理更新与显示
|
- 独立的 `TriangleRasterizer` 模块，用于后续填充三角形
|
||||||
|
|
||||||
当前 `main.cpp` 中已经可以直接绘制一个填充三角形，用来验证基础光栅化逻辑。
|
当前 `main.cpp` 主要用于验证基础链路，程序启动后会在窗口中绘制三条彩色线段组成的三角形轮廓。
|
||||||
|
|
||||||
## 技术选型
|
还没有完成的核心能力：
|
||||||
|
|
||||||
- 语言标准：C++20
|
- 完整接入实心三角形渲染流程
|
||||||
- 工程类型：Visual Studio C++ 项目（`.vcxproj`）
|
- MVP 变换
|
||||||
- 渲染方式：CPU Software Rasterization
|
- 深度测试
|
||||||
- 窗口与展示层：SDL2
|
- 重心坐标插值
|
||||||
- 开发环境：Windows + MSVC
|
- 光照
|
||||||
|
- OBJ 加载
|
||||||
|
- 可交互相机
|
||||||
|
|
||||||
选择 SDL2 的原因很直接：它只负责跨平台窗口和像素展示，足够轻量，不会替代掉软件渲染器本身的核心逻辑。
|
## 当前结构
|
||||||
|
|
||||||
## 依赖
|
|
||||||
|
|
||||||
项目当前依赖很少：
|
|
||||||
|
|
||||||
- SDL2
|
|
||||||
|
|
||||||
仓库内已经包含 SDL2 相关文件：
|
|
||||||
|
|
||||||
- 头文件目录：`libs/SDL2/include`
|
|
||||||
- x64 库目录：`libs/SDL2/lib/x64`
|
|
||||||
- 运行时动态库：`libs/SDL2/SDL2.dll`
|
|
||||||
|
|
||||||
## 构建环境
|
|
||||||
|
|
||||||
当前工程配置以 Windows 本地开发为主，推荐环境：
|
|
||||||
|
|
||||||
- Visual Studio 2022
|
|
||||||
- MSVC 工具链
|
|
||||||
- Windows 10/11 SDK
|
|
||||||
|
|
||||||
项目文件中启用了：
|
|
||||||
|
|
||||||
- `stdcpp20`
|
|
||||||
- `PlatformToolset=v145`
|
|
||||||
|
|
||||||
## 构建方式
|
|
||||||
|
|
||||||
1. 使用 Visual Studio 打开 `CPU-Software-Renderer.vcxproj`
|
|
||||||
2. 选择 `Debug | x64`
|
|
||||||
3. 直接构建并运行
|
|
||||||
|
|
||||||
说明：
|
|
||||||
|
|
||||||
- 当前工程的 SDL2 include/lib 路径写在 `.vcxproj` 里
|
|
||||||
- 现有配置里 `Debug | x64` 已配置 SDL2 头文件和链接目录
|
|
||||||
- 如果你移动了仓库位置，可能需要同步调整工程中的绝对路径
|
|
||||||

## 已实现模块
|
## 模块说明
|
||||||
|
|
||||||
### 1. Frame Buffer
|
### Core
|
||||||
|
|
||||||
渲染结果先写入 CPU 侧的 `std::vector<uint32_t>` 帧缓冲区，再通过 `SDL_UpdateTexture` 更新到纹理。
|
- `FrameBuffer`：管理 CPU 侧颜色缓冲
|
||||||
|
- `DepthBuffer`：为后续深度测试预留
|
||||||
|
- `Renderer`：为后续统一调度渲染流程预留
|
||||||
|
|
||||||
### 2. Rasterizer
|
### Math
|
||||||
|
|
||||||
当前已经实现：
|
- 放通用数学类型
|
||||||
|
- 当前以 `Vector2`、`Vector2Int`、`Vector3` 为主
|
||||||
|
- `Vector4` 和 `Matrix4x4` 目前还是占位
|
||||||
|
|
||||||
- `DrawLine`
|
### RenderData
|
||||||
- `DrawWireTriangle`
|
|
||||||
- `DrawFillTriangle`
|
|
||||||
|
|
||||||
其中直线绘制使用 Bresenham 思路，填充三角形使用包围盒扫描配合点在三角形内测试。
|
- 放渲染领域数据，而不是底层数学类型
|
||||||
|
- 当前包含 `Color`、`BoundingBox2D`、`Triangle2D`
|
||||||
|
|
||||||
### 3. 基础数学类型
|
### Rasterizer
|
||||||
|
|
||||||
当前工程已经定义了：
|
- `Rasterizer`：负责基础线段光栅化
|
||||||
|
- `TriangleRasterizer`：负责三角形填充相关逻辑
|
||||||
|
|
||||||
- `Vector2Int`
|
### Scene / Asset / Shading
|
||||||
- `Vector2`
|
|
||||||
- `Vector3Int`
|
|
||||||
- `Vector3`
|
|
||||||
- `Triangle`
|
|
||||||
- `Color`
|
|
||||||
|
|
||||||
这些结构会作为后续扩展 MVP 变换、深度测试、法线和属性插值的基础。
|
这些目录已经预留出来了，方便后面扩展到 3D 渲染流程，但当前多数还是占位类。
|
||||||
|
|
||||||
|
## 构建环境
|
||||||
|
|
||||||
|
- Windows
|
||||||
|
- Visual Studio 2022
|
||||||
|
- MSVC
|
||||||
|
- C++20
|
||||||
|
- SDL2
|
||||||
|
|
||||||
|
工程文件是 Visual Studio 的 `.vcxproj`。
|
||||||
|
|
||||||
|
## 依赖
|
||||||
|
|
||||||
|
仓库内已经包含 SDL2：
|
||||||
|
|
||||||
|
- 头文件：`CPU-Software-Renderer/libs/SDL2/include`
|
||||||
|
- Win32 库：`CPU-Software-Renderer/libs/SDL2/lib/x86`
|
||||||
|
- x64 库：`CPU-Software-Renderer/libs/SDL2/lib/x64`
|
||||||
|
|
||||||
|
## 构建与运行
|
||||||
|
|
||||||
|
1. 用 Visual Studio 打开 `CPU-Software-Renderer/CPU-Software-Renderer.vcxproj`
|
||||||
|
2. 选择 `Debug` 或 `Release`
|
||||||
|
3. 选择 `Win32` 或 `x64`
|
||||||
|
4. 构建并运行
|
||||||
|
|
||||||
|
说明：
|
||||||
|
|
||||||
|
- 工程里已经分别配置了 Win32 和 x64 的 SDL2 include/lib 路径
|
||||||
|
- 运行时需要让程序找到与平台匹配的 `SDL2.dll`
|
||||||
|
- 如果你移动了仓库位置，可能需要同步检查 `.vcxproj` 里的绝对路径
|
||||||
|
|
||||||
|
## 设计取向
|
||||||
|
|
||||||
|
当前代码结构遵循一个比较简单的原则：
|
||||||
|
|
||||||
|
- 纯数据类型放在 `Math` 和 `RenderData`
|
||||||
|
- 做事的模块放在 `Core`、`Rasterizer`、`Asset`、`Shading`
|
||||||
|
- 先把 2D 基础链路理顺，再逐步加 3D pipeline
|
||||||
|
|
||||||
|
这意味着现阶段更强调“结构和边界先理清”，而不是一次性把所有功能堆进去。
|
||||||
|
|
||||||
## 后续计划
|
## 后续计划
|
||||||
|
|
||||||
1. 完成稳定的三角形光栅化基础
|
按 `TODO.md` 的路线，后续会逐步补齐：
|
||||||
2. 加入 MVP 变换，实现 3D 顶点到屏幕空间的投影
|
|
||||||
3. 加入 Z-buffer，解决遮挡关系
|
|
||||||
4. 实现重心坐标属性插值
|
|
||||||
5. 实现 Blinn-Phong 光照
|
|
||||||
6. 支持 OBJ 模型加载
|
|
||||||
7. 实现相机控制
|
|
||||||
|
|
||||||
如果后续继续扩展，比较值得加入的方向还有：
|
1. 稳定的三角形填充
|
||||||
|
2. MVP 变换
|
||||||
|
3. Z-buffer
|
||||||
|
4. 属性插值
|
||||||
|
5. Blinn-Phong 光照
|
||||||
|
6. OBJ 模型加载
|
||||||
|
7. 相机控制
|
||||||
|
|
||||||
|
如果后续继续扩展，还可以考虑：
|
||||||
|
|
||||||
- Texture Mapping
|
- Texture Mapping
|
||||||
- MSAA 抗锯齿
|
- MSAA
|
||||||
- 更完整的数学库
|
- 更完整的数学库
|
||||||
- Shader 结构拆分
|
- 更清晰的 shader 输入输出结构
|
||||||
|
|
||||||
## 这个项目最终会变成什么
|
|
||||||
|
|
||||||
按当前路线推进后，这个项目会逐步具备一个小型软件渲染器的基本结构：
|
|
||||||
|
|
||||||
```text
|
|
||||||
Renderer
|
|
||||||
├─ Rasterizer
|
|
||||||
├─ Shader
|
|
||||||
├─ Camera
|
|
||||||
├─ Math
|
|
||||||
├─ OBJLoader
|
|
||||||
└─ ZBuffer
|
|
||||||
```
|
|
||||||
|
|
||||||
最终目标是实现一个不依赖 GPU 光栅化管线、但具备基本 3D 渲染能力的 CPU Renderer。
|
|
||||||
|
|
||||||
## 适合用来做什么
|
|
||||||
|
|
||||||
这个项目比较适合：
|
|
||||||
|
|
||||||
- 学习软件渲染器的基本实现方式
|
|
||||||
- 理解三角形光栅化、像素写入和屏幕空间坐标
|
|
||||||
- 作为后续学习图形学、渲染 pipeline、光照和模型加载的实验场
|
|
||||||
- 用于整理个人图形学项目经历
|
|
||||||
|
|
||||||
## 说明
|
## 说明
|
||||||
|
|
||||||
当前项目仍在早期阶段，很多功能还处于逐步实现中。README 中的“后续计划”部分表示目标路线，不代表这些能力已经全部完成。
|
这个项目现在更接近“正在搭骨架的 renderer”，不是一个已经完成的 3D 渲染器。
|
||||||
|
|
||||||
|
README 中提到的很多模块和目录，目的是反映当前的架构方向；其中一部分已经有初步实现，另一部分还只是为后续阶段预留。
