Math in game development

Scale · 03-25-2009, 12:35 AM

I was wondering what kinds of math are used in creation of games.
The ones i know about would be:

Cos and Sin and Tan for movement and looking around,
Parabola for projectiles like arrows.

What else?

Thanks!

Lots of physics. That's about all I'm sure about.

**Crazycarl** · 03-25-2009, 01:53 AM

Vector math, both 2D and 3D.

Also, knowing how to plot a complex line in xy space would be useful.

Elementary linear algebra.

matrices, transforms.. you're looking for degree level maths, dude.

Have you ever programed before?
It uses more math skills then you would think. More understanding then physically doing, however.

Probably involving some multiplication and division

No, the computer does that for you.

Yeah but you still need to type out the * and the /

If you complete the lower division requirements for a college degree in some science or engineering, you should have the math background for 3D game programming. But of course one can just easily pick up the material himself. Don't worry, it doesn't involve proof by reverse-induction or Central Llama Theorem. Just blindly applying formulae.

Theoretical and logical math.

in some cases making your own formulas

Well if you're in C++ what do the following expressions evaluate to:

19 / 2

and

19.0 / 2.0

So you do have to know a little bit about what you're doing.

You need linear algebra for graphics programming. Pretty much everything deals with matrices and vector math in 3D graphics programming. It's the main reason I hate graphics programming.

dont get me started on DSP.. :/

I'm doing an Advanced Engineering Mathematics course at the moment and we're going over Linear Algebra (Matricies) and Transforms. It's confusing as hell and I don't like it :P We just started a new topic on Functions too (eep)

Math always sounds annoying...until one encounters a complicated problem that can be greatly simplified with math.

Courses you need:

Algebra I
Algebra II
Linear Algebra
Differential Equations

These are all American names of the classes, of course. Sometimes Linear Algebra is called Algebra III and sometimes Linear Algebra and Differential Equations are tied together.

And obviously if you're taking classes in England or something they're going to be way harder and you're going to learn a ton more.

That's a good point. Math education isn't all about teaching facts about mathematics. The main goal of a math class to is provide students intellectual challenge in order to strengthen analytical skills. The subject of the class can be Algebra I or Topology. It is possible to make the students think very, very hard in either class.
