Simulating hector slam with kinect in a hector quadrotor

edit

Is it possible to create a 3D map for path planning using hector_slam and kinect held hector_quadrotor?

I could create a geotiff with laser scan. I tried adding a kinect sensor to the indoor_slam demo provided with hector_quadrotor. But I am not sure how to instruct hector_mapping to include the kinect sensor data and create a 3D map.

What should I be modifying to bring this into effect?
