Persis is a summer intern at a new video game software company, Generation Z Gamers. She is working on three-dimensional landscapes for a new role-playing video game Submarine Adventures. As her supervisor, what advice can you give Persis to help her create the illusion of three dimensions?a. Reds and blues make objects appear closer than yellows and greens. b. Use more texture on background rather than foreground objects. c. Continuous lines should only be used for distant objects. d. Converge parallel lines at the horizon to create a linear perspective.

d. Converge parallel lines at the horizon to create a linear perspective.

Explanation:

To create an illusion of three-dimensions, a linear perspective is the best way to achieve this. A linear perspective is a system used by artists and other game developers to create an illusion of depth on flat surfaces. When using this technique, all parallels lines are made to converge at a single vanishing point at the horizon, thereby giving it a three-dimensional look.

this null effect is caused by a weak manipulation and ineffective internal validity. in a scientific study, as the one dr. morimoto is trying to perfom, internal validity refers to the confidence placed in the cause-effect relationship and to how well an experiment is done and able to eliminate confounding variables.
