Quadtree
Locked

I was wondering if anyone had any quadtree code they wouldn't mind sharing? I couldn't find any on squeaksource.
Meanwhile, I'll get started :) Thanks, RS

Hi Robert,
I have an implementation of dynamic axis-aligned bounding-box trees in VisualWorks. They are basically octrees which may behave as quadtrees (two planes used to cut the space) or BSP-like trees (only one plane) depending on the number of objects that are cut by the splitting planes (maybe if you just need a qudtree it may be an overkill). Let me know if it may help you. Cheers, Andrés Robert Sirois escribió: > I was wondering if anyone had any quadtree code they wouldn't mind sharing?

Id love to see them, thanks. I'm just getting into it, so seeing even related code will be nice :)
I've been following some different examples online and piecing together one, so ill probably finish it just for the learning experience regardless.

Ok, now we only have to agree on how to transfer from VW to Squeak :).
Maybe this is a bit OT for the seaside list, I'll write you a private mail. Cheers, Andrés Robert Sirois escribió: > Id love to see them, thanks.

AFAIK MLS has some Monticello tools that allow him to publish from VW to a Monticello repository.

Browse the class side of DateAndTime and look through the methods. There's lots of convenience methods like #tomorrow, #yesterday, etc. and you can also add Duration (I think) objects to instances of DateAndTime with # , etc.
