Is there an example of picking objects using mouse?
I was just wondering if there's an example of picking and dropping objects using mouse in OpenGL? The tutorial # 32 on Nehe isn't that helpful. I know how to rotate an object or zoom etc. using mouse which i learned from Nehe tutorial # 48 and others. However, i couldn't find a good example of how to pick an object and then drop or even better if one could move an object (means translate from one spot to another) using mouse. Any example or ideas would be apperciated. Thanks in advance!!
