Cage Deformer Plugins for Maya
License: MIT License
Hi man! first of all thank you for sharing the code! I am compiling and trying a series of deformers for evaluation purpose.
Compiling under centos 6.5 was a bit tricky, mainly had tons of alignment issues with Eigen, although following the Eigen guide i was not able to run the deformer until you compile with -DEIGEN_DONT_VECTORIZE, just so you know if you want to compile for linux.
Now to the bug at hand, I am running a simple test, a cube wrapping a sphere, the deformation looks pretty nice but as soon as I move a couple of vertices of the cage, I get a hard crash with the following error:
maya.bin:CageDeformerMaya/cageDeformer/../affinelib.h:565: void AffineLib::parametriseGL(const Matrix3d&, Eigen::Matrix3d&, Eigen::Matrix3d&): Assertion
m.determinant()>0' failed.`
I wanted to know do you think this is just a bug in the affine library or is a major numerical instability in the algorithm itself? Any feedback on the matter would be appreciated.
