gmorph is a research code for 3D morphing between two meshes with arbitrary connectivities, including an implementation of the following papers:

• Takashi Kanai, Hiromasa Suzuki, Fumihiko Kimura: "Metamorphosis of Arbitrary Triangular Meshes," IEEE Computer Graphics and Applications, Vol.20, No.2, pp.62-75, March/April 2000.

This software was originally developed in 1997-1998 and was renovated in 2016 to build successfully with Visual Studio 2015 (VS2015).

This software is provided exclusively for Windows.

1. Double-click on src\OpenGL.sln (A solution file for VS2015) or src\gmorph-vs2019.sln (for VS2019), then "build the solution". Upon successful completion, you can find the executable in src\Release\gmorph.exe or src\x64\Release\gmorph-vs2019.exe (64-bit binary).

2. In the data.v2.0 folder, all examples used in the paper are included. You can check the 3D morphing animation as follows:

   • Copy the execution file gmorph.exe (or gmorph-vs2019.exe) to a folder including a .gmh file.
   • Execute gmorph.exe (or gmorph-vs2019.exe).
   • "File" -> "Open" -> "GMH file" to load a .gmh file.
   • "Morph" -> "Create PPD" to create an interpolation mesh.
   • "Display" -> "Interp. Mesh"
   • "Morph" -> "Start Morph," then you can see the 3D morphing animation.

This software uses MFC (Microsoft Foundation Class). To build this software, VS2015/VS2017 Professional or higher versions are required for Windows applications.

This software also requires the Eigen library. When you execute git clone with the --recursive option, you will also get the Eigen library as a submodule in external/eigen:

git clone [email protected]:kanait/gmorph.git --recursive
