Do some 3D Modelling

Medium of instruction - English, Hindi or Marathi Although I never did 3D modeling/animation, I do understand the concepts/terminology (e.g. Rigging, Matchmoving green screen, Rotoscoping etc). I need someone to explain me (screen sharing session) this week(flexible) to quickly explain me once scene or model is set up, how to use camera(s) to take a specific shot. I mean, if it is a house, how can I start from the door and go into different rooms and create a video. Any tool will do. All I want is a conceptual understanding. When I watch movies with virtual sets, I always wonder how they take shots at different angles of the virtual set.
