Reword whats below plz?

computer graphics and visualization generate highly realistic objects and environments that are essential in many applications such as video games and virtual environments for simulations. 3D computer graphics requires in-depth understanding many mathematical concepts such as geometry, linear algebra, and trigonometry, and strong programming skills to develop effective and efficient data structures, algorithms, and implementations. In addition to visual representations, many simulations and games also contain complex logic that controls dynamic entities such as human characters, vehicles, weapons, and their interactions. In this programming assignment, you will develop a transportation simulation (Figure 1) that contains a simplified intersection (including traffic lights and surveillance cameras), two roads, and a vehicle. You will generate the control logic of the traffic signals, vehicle driving simulation, and multiple views of the simulation from different perspectives. Programmers in the real world rarely develop an entire application totally from scratch; instead, it is most likely that the programmer will develop an application based on an earlier version of the application or use some other existing software libraries. This is one reason that the instructor has developed a base project for this programming assignment and will provide it to the class as your starter code. The second consideration for providing a base project is the difficulty of the project if developed from scratch (and the difficulty of 3D graphics programming in general)
