The project implements the Catmull-Clark subdivision surface algorithm with C++.

The source includes following knowledge:

• half edge data structure representing mesh.
• C++11 syntax and shared_ptr, weak_ptr.
• freeglut opengl library.
• obj file reading implementation.

Build

In ubuntu:

$ sudo apt install -y freeglut3-dev
$ mkdir build && cd build
$ cmake .. && make -j

In macOS:

$ brew install freeglut
$ mkdir build && cd build
$ cmake .. && make -j

Usage

• ccsubd filename.obj
• up/down/left/right arrow key -> up/down/left/right rotation
• c key -> subdivison one time
• u key -> previous mesh
