why is there a limit to the number of gpu_ray sensors in the gazebo world ?

Hello all,

I am trying to accurately simulate a velodyne sensor with 16 plains, As the needed angular resolution is 0.1deg and required rotation rate is 10Hz I attempting to achieve this by rotating 36 ray sensors that are, tilted on the side.

if i use regular ray sensor, things works fine, But if i switch to gpu_ray. and use more than 16 gpu_ray sensors some of them do not produce any data, and if i use more than 24 gazebo is crashes

I am using Gazebo 8, on Ubuntu 16.04 CPU : Xeon(R) E5-1620 v3 @ 3.50GHz × 8 , RAM : 16G, GPU : Nvidea Quadro K2200,

If anybody have any Idea, please, give me some direction

why the gpu_ray sensor number in a world is limited ?

Hello all,

I am trying to accurately simulate a velodyne sensor with 16 plains,

plains :

As the needed angular resolution is 0.1deg and the rotation rate is about 10Hz, I attempting to achieve this by rotating creating a plugin that reads data fro 36 rotating, ray sensors, that are tilted on the side.

if If i use regular ray sensor, sensors, things works fine, are working fine. But if i switch to gpu_ray, and use more than 16 gpu_ray sensors some of they them do not produce any data, and if i use more than 24 sensors gazebo is crashes

I am using :
Gazebo 8, on 8
