What is the mean of avoiding collisions using full 3D data?

ros-planning / 3d_navigation

Global and local path planner plugins for ROS move_base which move the robot in 2D (x,y,angle) but avoid collisions using full 3D data (robot meshes and environment octomap).

What is the mean of avoiding collisions using full 3D data? #1

Hello, I don't know the meaning that avoid collisions using full 3D data. I only know if you use move_base, the navigation map is OccupancyGrid. And it's 2-D grid map. Can you explain the collisions using full 3D data?

The project seem to be laid aside. What is going on for now?

In my understanding , when the collision could be taken place by 2d grid map(3 types of 2d maps) , then it could using ODE method to checking if it will collide in 3d map.
