### GpuRaySensor.hh missing in 1.3?

Looks like GpuRaySensor.hh went missing in Gazebo 1.3. I checked out the lastest source from the repo:

~/src/gazebo$ls gazebo/sensors/Gpu* gazebo/sensors/GpuRaySensor.cc gazebo/sensors/GpuRaySensor.hh  But in my installed (Ubuntu package), there is no more GpuRaySensor: /usr/include/gazebo-1.3$ ls gazebo/sensors/Gpu*
ls: cannot access gazebo/sensors/Gpu*: No such file or directory


Pretty sure it was there in 1.2 and earlier as I had compiled worked on an extension to the base GpuRaySensor class.

### GpuRaySensor.hh missing in 1.3?

Looks like GpuRaySensor.hh went missing in Gazebo 1.3. I checked out the lastest source from the repo:

## Update

Because I am impatient, I tried pulling in the relevant sources into my sensor that were missing from installed Gazebo 1.3 (GpuRaySensor.hh/.cc, GpuLaser.hh/.cc). But then ran into the following compile error:

In file included from .../plugins/src/GpuLaser.cc:27:0:
/usr/include/gazebo-1.3/gazebo/rendering/ogre_gazebo.h:22:18: fatal error: Ogre.h: No such file or directory


Looks like Ogre.h is in,

/usr/include/OGRE


Not in,

/usr/include


Ultimately is this why GpuLaser didn't make it into 1.3?
