// I've made some changes to the Scenery handling. Basically just tidy ups.
|
|
// The main difference is in tile.[ch]xx where I've changed list<fgFRAGMENT> to
|
|
// vector<fgFRAGMENT>. Studying our usage patterns this seems reasonable.
|
|
// Lists are good if you need to insert/delete elements randomly but we
|
|
// don't do that. All access seems to be sequential. Two additional
|
|
// benefits are smaller memory usage - each list element requires pointers
|
|
// to the next and previous elements, and faster access - vector iterators
|
|
// are smaller and faster than list iterators. This should also help
|
|
// Charlie Hotchkiss' problem when compiling with Borland and STLport.

// - saving the face list for each fragment with the fragment records.
|
|
// - code to intersect the current vertical line with the proper face in
