# Grid Class Reference

Grid for collision detection. More...

## Detailed Description

Grid for collision detection.

The grid is intended to speed up collision detection by reducing the number of exact collision tests with objects which share some GridCell s.

  GridCell, GridObj

Bug:
  The Grid class and friends are probably not multi-thread-safe, i.e., several threads asking the same grid for a list of intersecting boxes will get different (wrong) answers. (This is because of the cycle counters.)

The documentation for this class was generated from the following file:

- ColGrid.cpp
