};

Fields

std::vector<uint32_t> vertices

Vector of indices to the vertex list.

mrpt::math::TVector3D normal

Normal vector.

Construction

TPolyhedronFace()

Fast default constructor.

Initializes to garbage.

Methods

double area(const std::vector<mrpt::math::TPoint3D>& vertices) const

Given a set of vertices, computes the area of this face.

void getCenter(const std::vector<mrpt::math::TPoint3D>& vertices, mrpt::math::TPoint3D& p) const

Given a set of vertices, get this face’s center.
