Have you ever wondered how does google 3D map work? Or, have you ever observed 3D objects in games or movies that look so real, it is impossible for you to believe that it was modeled and rendered artificially?

Well, the answer might be Photogrammetry. Photogrammetry is often defined as the science of taking measurements from photographs. In a simpler term, you can scan an object and create your own 3D model through a free software just by taking a few overlapping pictures of the model. Need fancy cameras? No. You can even use your cellphone camera and take some pictures by hand. Benefit of using photogrammetry over laser scanning is that photogrammetry can provide a vrml file format, that means that it would also include the surface colors of the scanned object. Whereas, laser scanning fails to capture the colors of the surfaces and can only provide an stl file with no color data.

Imagine you slipped on a wet floor and fractured your feet. The doctor recommends you not to exert any pressure on your feet for the next 2 months. You still have classes to attend, assignments to submit and exams to write in these 2 months. You decide to stay strong and be brave enough to continue to go to school, instead of skipping the whole semester.
On your first day of class after the accident, you reach to your school only to realize that your class is on the third floor and the lift is out of order. What do you do?
