Assignment: Functions
Using Processing, write a single program containing definitions for all the functions described below. Make sure to put a comment above each function definition with a description of the function, each parameter's purpose, and the return value's purpose (if there is a return value at all). Use rgb color mode!
Define the following three functions:
1) A function named howBright. It should compute the visual brightness of a given rgb color, specified by three parameters for the red blue and green components. The function should return the computed brightness value as a float.
Hint: The brightness of an rgb color is the arithmetic mean (average) of the three component values. So, add them up and divide by three.
2) A function named drawCar. This function should draw an automobile roughly 100 by 100 pixels in size centered at the x,y coordinates given by the first two float parameters. Three more float parameters specify the rgb components of the primary paint color, and the last three float parameters specify the rgb components of the trim color. Use at least 8 shapes to make the car. This function need not return any value.
Hint: You'll need 8 float parameters: two for location, then three for paint color components, then three for trim color components.
3) A setup function that makes two cars appear in the display window on a stationary roadway: one car in the middle of the left half of the screen, and the other car in the middle of the right half of the screen. The left car should have totally random colors for the primary paint color and for the trim color. The right car should be a grayscale car with paint and trim the same brightness as the left car. You must invoke your drawCar function once to make each car, and you must invoke howBright to determine the colors for the right car.
Hint: Choose 6 random color components, store them into 6 variables, compute the brightnesses of those two rgb colors, and store those into two more variables. Invoke drawCar on the left with the 6 color variables. Invoke drawcar on the right with the brightness variables, provided three times each as three-component grayscale colors.
Note that this is not an animation, because there is no draw function defined.
Remember to put a header comment at the top of your code: name, date, class, assignment, and a description.Also put comments above each function definition describing what the function does, its parameters (if any), and its return value (if any).
