Member Function Documentation

virtual void chrono::geometry::ChTriangleMesh::GetBoundingBox ( double &  xmin,
double &  xmax,
double &  ymin,
double &  ymax,
double &  zmin,
double &  zmax,
ChMatrix33<> *  Rot = NULL 
) const
overridevirtual

Compute bounding box.

If a matrix Rot is not null, it should compute bounding box along the rotated directions represented by that transformation matrix Rot. It must be overridden by inherited classes.

Reimplemented from chrono::geometry::ChGeometry.

virtual GeometryType chrono::geometry::ChTriangleMesh::GetClassType ( ) const
overridevirtual

Get the class type as unique numerical ID (faster than using ChronoRTTI mechanism).

Each inherited class must return an unique ID.

Reimplemented from chrono::geometry::ChGeometry.

Reimplemented in chrono::geometry::ChTriangleMeshConnected, and chrono::geometry::ChTriangleMeshSoup.
