# Nav2 Voxel Grid
|
|
|
|
The `nav2_voxel_grid` package contains the VoxelGrid used by the `Voxel Layer` inside of `nav2_costmap_2d`. The voxel grid itself is simply a 2D char pointer array of the map size with bit locations corresponding to voxel values (free, unknown, occupied , etc).
|
|
|
|
It is branched out as a separate package for use in other applications where a dense voxel grid representation may be useful. It also contains implementations of 3D raycasting.

## ROS1 Comparison
|
|
|
|
This package is a direct port to ROS2 for use in the voxel layer.
