I under stand these, I think.
You just created these lines/pictures/graphs by creating a equation?
That's it. If you know a way to create one brick, (
http://blockland.wikia.com/wiki/Spawning_bricks) all you need is a formula and a for loop (or more than one for loops) to create several bricks.
For example, let's say you know a formula y=x^2. You'll need a for loop for the values of x (let's say from -10 to 10.) Then the computer will compute the square of x, and assign it to y.
You can assign a constant to z, because it's a 2-dimensional graph.
Creating a 3-D graph is just the same, but you simply need more for loops.
Now, the fun thing is, I don't have to know the equations, I just look them up on the internet -- I find something that looks fancy on Wikipedia, I say "That looks cool, what's the formula for that?" So I don't need to know ultra-high level math. I just need to know the formula.
