Questions: 1. Formulate the Homogeneous coordinates transformation of a point (x,y,z) to handle the perspective projection. [C02][2 marks] 2. A camera's projection system is determined by its focal length, screen height, and screen aspect ratio (ratio of width to height). Given a camera with focal length f, screen height h, and aspect ratio a, give the screen position of 3D point x=(x,y,z), specified in the view coordinate frame of the camera. Assume a perspective projection. (CO2][3 marks]
