inline

Constructor. unfolded Flat mesh possibly intersecting the domain boundaries.

Member Function Documentation

void addThreeFlatTrianglesOneOut ( gsMesh< T > &  mesh, const VertexHandle &  v0, const VertexHandle &  v1, const VertexHandle &  v2  ) const

protected

Adds three flat triangles in the situation where one of the vertices of the original triangle is outside the domain. v1 is outside the domain, v0 and v2 inside.

void addThreeFlatTrianglesTwoOut ( gsMesh< T > &  mesh, const VertexHandle &  v0, const VertexHandle &  v1, const VertexHandle &  v2  ) const

protected

Adds three flat triangles in the situation where two of the vertices of the original triangle are outside the domain. v1 is inside the domain, v0 and v2 outside.

real_t correspondingV ( const VertexHandle &  v0, const VertexHandle &  v1, real_t  u  ) const

protected

Finds the v-coordinate of the point on the line segment (v0, v1) that has the u-coordinate u.
