Isometric Shape Interpolation

Python implementation of Baek, S., Lim, J., & Lee, K. (2015). Isometric Shape Interpolation. Computers and Graphics, 46(C):257--263. This is a minimalistic reimplementation of the authors' C++ code in Python. The original C++ code relied upon a bunch of 3rd party dependencies, such as SuiteSparse/CHOLMOD for sparse matrix algebra, making it extremely difficult to compile and quite hard to read. The new implementation relies on simple NumPy and SciPy codes, augmented by Open3D and pyquaternion libraries.

Not yet available:

• Meshes with boundary. Currently, it only supports closed (watertight) meshes.
• Speed. It is far slower than the original C++ code.

The above issues will be addressed in the near future.

Get Started

Clone this repository by running the following comand.

git clone -https://github.com/stephenbaek/isoblend.git
cd isoblend

Create a virtual environment using conda. Alternatively, you could use virtualenv.

conda create -n isoblend python=3.8 ipykernel nb_conda_kernels
conda activate isoblend

Install dependencies.

pip install -r requirements.txt

You are now ready to run the code. For the usage, see demo.ipynb.
