示例1: InitOSRay
void CTraceSolverSweptObject::InitOSRay( void )
{
// transform ray into object space
m_rayLengthOS = m_ray->m_length;
m_obstacle->TransformPositionToLocal( m_ray->m_start, m_rayStartOS );
// no translation on matrix mult because this is a vector
m_obstacle->TransformDirectionToLocal( m_ray->m_dir, m_rayDirOS );
// add_multiple with 3 params assumes no initial value (should be set_add_multiple)
m_rayCenterOS.add_multiple( &m_rayStartOS, &m_rayDirOS, m_rayLengthOS*0.5f );
m_rayEndOS.add_multiple( &m_rayStartOS, &m_rayDirOS, m_rayLengthOS );
