## Member Function Documentation

template<class T >

virtual void irr::scene::CMeshBuffer< T >::append | ( | const IMeshBuffer *const | other | ) | `[inline, virtual]`

Append the meshbuffer to the current buffer.

Only works for compatible types, i.e. either the same type or the main buffer is of standard type. Otherwise, behavior is undefined.

Parameters:

  | other | Meshbuffer to be appended to this one.
