ScanLine

A CPU renderer using z-buffer scan line algorithm.

Course project for Computer Graphics.

Features

Main feature: render 3d models using z-buffer scan line algorithm on CPU

• Support: camera manipulation
• Support: fps ~30 for small scenes
• Support: common model formats
• Support: texture
• Support: post-render effects using shaders (like anti-aliasing)
• Not support: lighting
• Not support: concurrency

Dependencies

Prebuilt dependencies for Windows 10 x64 VS2015 are included in the repo.

• GLEW
• GLFW3
• SOIL
• ASSIMP

Usage

1. Prepare dependencies if necessary

2. Use CMake to configure the project

3. Build (only tested on Win10 VS2015 x64)

4. Run the program given an integer [1-4] as argument, e.g. :

   ./ScanLine.exe 2    #choose the 2nd prepared model

5. You can use mouse to rotate and zoom the model

Basic Process

1. Read models as DrawableObject class
2. Use ZBufferScanLine class to rasterize the scene into a single quad of pixels
3. Render the quad on a window using a simple shader
