v0.16.0
51e0172

This is a major release, bringing full support for expression PCA models. MorphableModels can now either contain no expression model, a set of blendshapes, or a PCA expression model.
The fit_shape_and_pose supports both as well, and calls either the _linear or _nnls solver, depending on whether a model contains blendshapes or an expression PCA model.

The main changes that go along with that:

  • Updated the MorphableModel file format to version to 2 to include an optional expression model. Version 1 models can still be read.
  • Added a flag ExpressionModelType to MorphableModel to easily query the type of the expression model.

Note: The behaviour of MorphableModel::get_mean() has been changed: It now returns the overall shape and expression mean. (see #188)

Other small additions:

  • Updated the BFM2017 converter script to convert and save the expression PCA model too.
  • Added a fitting function for fixed, given correspondences, that runs the fitting loop without contour fitting. (see here)
  • The online doxygen documentation has been updated to v0.16.0.

As always, when updating from the GitHub repository, make sure to run git submodule update --init --recursive.

The binary files are provided for convenience only - it is recommended to build the examples from source, and use the library by cloning the GitHub repository.

Windows binaries are compiled with Windows 10 64bit, Visual Studio 2017. A .whl with python bindings for python 3.6 is available on PyPI.
Linux binaries are compiled with Linux Mint 18.3, based on Ubuntu 16.04, gcc-7. Make sure to follow the instructions for how to use gcc-7 with pip if using the Python bindings on Linux.
