Welcome to SilverGL-Soft_Render_Pipeline – an open-source project focused on implementing a high-performance soft rendering pipeline in C++. This project is built from scratch to demystify the inner workings of rendering in computer graphics, while pushing the boundaries of what can be achieved with a pure C++ approach.
Thanks to the valuable guidance from zxx43, my understanding of the soft rendering pipeline has significantly deepened. I also want to acknowledge Angelo1211 for their project, which further influenced the development of this pipeline.
As a computer graphics enthusiast, I’ve always been fascinated by the complexities of rendering, especially in the world of AAA game development. By embarking on this project, I aim to:
- Apply my C++ knowledge to a real-world rendering pipeline.
- Gain deeper insights into computer graphics theory and implementation.
- Move beyond the black box of game engines, creating a custom PBR renderer and implementing lighting models from scratch.
Here’s a quick overview of what this project offers:
| Feature | Description |
|---|---|
| Math Library | MATRIX, VECTOR, and other essential math utilities. |
| Data Structures | FrameBuffer, DepthBuffer, Triangle, etc., to support rendering functionality. |
| Raster Rendering | Scan line algorithm, barycentric coordinates, and multiple rasterization methods. |
| Graphics Pipeline | Complete pipeline: initialization, coordinate conversion, clipping, culling, etc. |
| Shader System | Basic & advanced shaders: Diffuse, Blinn Phong, Texture, and PBR Cook-Torrance. |
| Texture Module | Supports Linear, Nearest, and Tile sampling with colors, normal maps, and AO. |
| Model Loading | .obj model loader for 3D assets. |
| Resource Management | Efficient management of textures and shaders. |
| Control Systems | Key input system and display manager based on the Windows framework. |
- Programming Language: C++
- Framework: Windows
- Reference Libraries: stb_image
- Development Environment: Visual Studio 2017
Note: This project requires only basic C++ knowledge. It’s designed with simplicity in mind, so even beginners to graphics programming can get started with the fundamentals of rendering.
