Hi,
Maybe you are aware of the USARSim 'mod' for UT3 which uses the UT3 engine for a robotics simulation environment for the Urban Search And Rescue competition at RoboCup (http://www.robocup2010.org/competition_Category.php?c=2). In this competition, a team of autonomous robots (not cyborgs, but robots that are 'boringly real life') needs to find it's way through unknown territory to aid rescue teams. They do this by creating maps of the environment, locating victims and navigating dangerous terrain.
I am working on a Masters' project at the University of Amsterdam. Our project is to add smoke and fire to the simulation. We keep alogbook at http://code.google.com/p/usarsim-smoke-fire/ . In unreal, there are many ways to visually create smoke and fire (particle systems, different fogs, etc). Most robots in the simulation do not really use the visual feedback from UT, but 'see' through e.g. laser beams that they send out, like they do in real life.
Now the problem:
To have the different sensors interact with the smoke in a realistic way, I want to load a texture to memory, and request specific pixel values from that texture, like 'the pixel at (20,30)' or 'the pixel at (431,425)'.
I do not want to render the texture, just get specific pixel values from it. Is there any way to do so? I have looked through all Texture-related unreal code files, but couldn't find something like that. There was nothing in the forums either.
Thanks,
