WebBy convention, the methods perspective() and lookAt() will assume a right-handed coordinate system. This convention was established for OpenGL and first realized in the OpenGL Utility Library (GLU). JOML follows this convention. In addition, JOML also supports a left-handed coordinate system, as is used by Direct3D’s matrix library.
