1. Platform and thirdparty libs

• Win10
• VS2012 or higher version, X64
• OpenMesh
• OpenGL
• Eigen

2. Core code

• locate in: /MeshDeformation/MeshDeform/PoissonDeform/PoissonDeformation.cpp (calculate gradient and divergence)
• /MeshDeformation/Utility/MeshLaplacianSolver.cpp （build laplacian matrix）

3. Usage

The test model locate in "/test_model" directory, include the model and control points.

• 1）click 打开 button，select cuboid.obj in "/test_model"
• 2）click 泊松变形
• 3）click 导入边界 on the left pannel, select cuboid.txt in "/test_model"
• 4）select the bottom region of the cuboid，click 设定固定区域 on the left pannel
• 5）click 计算拉普拉斯矩阵 on the left pannel
• 6）provide 3 interactions：A. rotate with Y axis(mid button of mouse + Ctrl), B. rotate with X-axis(mid button of mouse + Shift) C. translate(Ctrl+ mid button of mouse)
• 7）click 泊松变形

4. Paper analysis in Chinese
