Home security without the grief

Well that explained it.

In graphics, a bounding box is the smallest box that encloses the object in question. This explains the picture posted by Argent.

In this context, we're talking about the space being monitored by a security device. The LSL scripting language has a sensor that detects avatars within an essentially spherical space. Most rooms, however, are rectangular in shape. With a simple approach, the sensor either misses the corners of the room or else extends beyond the walls, acting on avatars that may be in a place they have a right to be in.

With more effort, you can provide a security orb with the locations of the walls. It can use the sensor to find all nearby avs, and then check the actual location of the av against the locations of the walls - the "bounding box" - to determine if the av is really inside the space being protected.

Note that the walls don't have to be real. I'm just using that word to help with the explanation.

BANLINES! - the only security needed from 0-50m of gound level (kidding, I'm fucking kidding)

I really like Argent's cat toys suggestion, but this is what I use
