Currently im working on a 3D map editor, i actually worked on it since 2008, rewrote it hundreds of times and now i have to do it again, because im unable to find fast object picking for my editor.
Tried many things and most of them fail or are too slow.

The rest of the features are easy. The editor is for specific game, made in 1999, my most favorite game and that's why i work on map editor for 5 years now, i had many months of doing my other things, while this project was just "freezed".

Now im again on it. Im doing it in OpenGL and Delphi 7 Personal Ed.

For me, making this editor, is alot more interesting than making some game.
Im not much of a gamer, i only play few games, including the favorite one.
