zooming at mouse position on a 3d object that can pan and rotate.

I’m looking for help with my project. The project is to write code for zooming at mouse position on a 3d object that can pan and rotate. The programming language I’m using for this project is vb.net with opentk. Currently, the 3D object is able to pan and rotate which is great. The new feature I’m looking to add is having the object zoom into the mouse position. The desired zoom level is close-up so the user can have a more immersive experience. If you have the expertise to complete this project then I’d love to hear from you!
