Member Function Documentation

Vec2D PointChain2D::Vec2DByIndex (  int  index  )

Position at node index. Parameters: index  node index Returns: position of interest

Vec2D PointChain2D::NormVec2DByIndex (  int  index  )

Unity vector normal to point chain at node index. The point chain direction is estimated by parabolical connection of predecessor, current node and successor. The direction is turnd by 90 deg against mathematical postitive rotation (in fact: let y turn to x). Parameters: index  node index Returns: unity normal vector of interest

void PointChain2D::Append (  AI_Sign_Enum  dir, const PointChain2D &  ptChExt )

Append a point chain. Parameters: dir  orientation of appending point-chain ptChExt  point chain to be appended
