Geometry::getInsideBox
bool getInsideBox(Vector3d p1, Vector3d p2, Vector3d position)
Verify if a point is inside a box.

Geometry::getBoundingBox
void getBoundingBox(const vector< Vector3d > &points, vector< Vector3d > &box)
Calculate the bounding box of a group of points.

Geometry::getInsidePolygon
bool getInsidePolygon(const vector< Vector3d > &polygon, const Vector3d &point, string extrude_direction)
Verify in a point is inside of a polygon.
