Member Function Documentation

clip()

std::vector< Eigen::MatrixXd > polyfem::utils::TetrahedronClipping::clip ( const Eigen::MatrixXd &  subject_tet, const Eigen::MatrixXd &  clipping_tet  )

static

Clip a tetrahedron using tetrahedron.

Parameters

[in]	subject_tet	Tetrahedron to clip.
[in]	clipping_tet	Tetrahedron to clip.

Returns

Tetrahedralization of the clipped (convex) polyhedron. Each entry is a matrix of size 4×3 containing the four vertices of each tetrahedron.
