Good Day Everyone,
I have been using ROS for a couple of weeks now and have grown to like
the RVIZ stack. Although, RVIZ does not currently support dynamic texture loading
which would be beneficial if an individual wanted to to re-project a camera image

into the 3d space.

There are a few examples of dynamic texture loading in rviz. For example, the ROSImageTexture (src/rviz/image/ros_image_texture.h/cpp) translates sensor_msgs/Image messages into Ogre textures. Note that I use an old API for it currently, the new one is documented in the Ogre manual: http://www.ogre3d.org/docs/manual/manual_64.html#SEC293

I tried modifying RVIZ to do that by implementing image retrieval for markers.

as follows
When a marker is received and is of type VISUALIZATIONMSGS:: ...IMPLANE

--->create the marker as usual in rviz.
---->pass a message to an image grabber thread which pulls the image for that marker
from another node via a service.
------->When image is ready, find marker corresponding to that image and create a texture out of that image

-------->Apply that texture to the marker.

Without some code it's impossible to know what's going wrong.

the last step is where i get problems. In loading the texture and applying it to the marker
I followed ogre's tutorials on creating a dynamic texture but that didnt work.

SO IS THERE ANYONE WHO KNOWS HOW TO CREATE DYNAMIC TEXTURES IN OGRE
MAYBE A LINK
I WILL BE VERY GRATEFUL

Please don't shout.
