Thanks, I am using Win XP, I want to remain generic in Web Cams.
I know C++ ( Using Dev C++ ) , Java , last night got Visual C as well just to solve the mystery of Video.
Trying over OpenCV , but unable to compile the example codes , probably setting issue.
Selection of C++ or Java so far is equally good for me.
My idea is to make a shooting game, the scenes of game ( as on monitor ) will be displayed on Wall using Video Projectors and Web cam to continuously capture the scenes. One Function will keep a look out for Laser Spot in the scene made by a laser gun by playing kids, track location of spot and compare with polygon of flying duck / airplane in the scene to declare hit or miss.
