Member Function Documentation

bool GRE::CLIPPING3D::ClipPoint (  DPOINT3DH &  point  )  [static]

Clip point. Returns: true if point inside unit cube

bool GRE::CLIPPING3D::ClipPolygon (  const DOUBLE_ARRAY< DPOINT3DH > &  input, DOUBLE_ARRAY< DPOINT3DH > &  output )  [static]

Returns: true if polygon intersects unit cube

bool GRE::CLIPPING3D::ClipSegment (  DPOINT3DH &  point1, DPOINT3DH &  point2 )  [static]

Clip segment with endpoints point1 and point2. If segment intersects unit cube than point1 and point2 contains endpoints of intersection in return. Returns: true if segment intersects unit cube
