Question

A computer's brain is just a bunch of numbers and the math that makes those numbers meaningful. One way computers add meaning to all the raw data is to present it graphically in three dimensions. Flight simulation is one example. It turns out that presenting 3-dimensional scenes requires the computer to solve systems of equations, sometimes quite large systems, with x, y, and z variables representing three directions in space. Computers solve systems of equations with matrix math, which you'll learn about in the next unit.
Give examples of 3D graphics and how x, y, and z figure into the topic

Answer 1

when you use x, y, and z variables you are using 3d
when you use x and y you use 2d

Answer 2

this is an open ended question trying to get you to apply what you have learn so far.
Not sure if anyone can answer this for you

Answer 3

computers use binary code (I believe it is machine code)

Answer 4

@precal to be more precise it is 0 and 1 and you are right

Answer 5

You can think of X, Y , and Z as this. X and Y create a plot like floor for your 3d graphics where x is front to back, y is side to side and z is up and down

Answer 6

A graphic image is made of pixels, a 2d image will have pixels in horizontal and vertical direction. Depending on the the pixel's value at a location, it's brightness will vary.
Here a system of 2 variables will be used.
For 3d-graphing and 3d images a third dimension or depth will also come in picture. We'll use a system of 3- variables here.

Answer 7

i thought a computers "brain" was a bunch of electrical voltages ....

Answer 8

if you like video games look up hammer editor

Answer 9

http://www.youtube.com/watch?v=HmzNQoRl7d0&feature=related . This shows you how it works.... the top left screen is visualy showing what you're building, the top right is the xy-plane which is sort of like the blue print to your floor, etc. the bottom two screens are the yz-plane and the xz-plane
