A random thought. Without 'holodeck' technology, I would think that this is more difficult than actually sensing the bullet. I wonder if it would be against the rules of shooting if shooters were given some sort of attachment that they could put on their scopes, which will project a fake target (generated from 3D rendering) for them. Then, it would just be a matter of working out if their bullets hit the target virtually. We'll have the XYZ position and angle of their rifles. Wind speed could be gotten from an external sensor. Same for humidity. But then, that would take away all the fun, wouldn't it? -- with metta, Shawn Tan Aeste Works (M) Sdn Bhd - Engineering Elegance http://www.aeste.net -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
