vtRoadMap contains a sets of nodes (TNode) and links (TLink) which define a transportation network.
It can be loaded and saved from RMF files, an ad-hoc Road Map Format which is overdue to be replaced by some clean, extensible standard for transportation networks. Unforunately, such a standard does not yet exist.
Find the node closest to the indicated point. Ignore nodes more than epsilon units away from the point.
bool vtRoadMap::ReadRMF | ( | const char * | filename | ) |
Read an RMF (Road Map File) Returns true if operation sucessful.
void vtRoadMap::RemoveLink | ( | TLink * | pLink | ) |
Remove a link, which also deletes it.
void vtRoadMap::RemoveNode | ( | TNode * | pNode | ) |
Remove a node, which also deletes it.
