I have a cube in openTK (openGL C#) and I want it to respond to mouse clicks. Is there any inbuilt function to do this? I would be very glad to have some help on the subject as I cannot find the right keywords to find it in google. All I need is a function that would return the area it currently occupies on the 2D screen. Then I could find if the mouse has clicked on this area. Any help is appreciated.

OpenGL does not have a built-in function for object picking. The Picking example shows one way to implement this in OpenTK. Depending on your project, there may be simpler or faster ways to do this.
