# Thread: New (possible) video: 3D Math

1. ## New (possible) video: 3D Math

Hi,

One topic I struggled with a lot in 3D programming was all the damned math.
And I find myself struggling with it in Python and LScript and Unity, when I need to script something that does a thing in 3D space.

It seemed like I went through a year where about once a week I'd need to understand how to properly rotate this or that so there wasn't a gimbal lock. Or I'd need to figure out how to tell if one player was facing another, or facing away, or how far to rotate them so they would face each other. How does a figure walking on an uneven terrain keep generally upright, but track the ground, while chasing something that moves through the air? How do you make aliens crawl along the walls and ceilings while they chase a person running down the hall?

Fun times.

But it turns out this stuff is really easy once you wrap your head around a handful of math concepts. 

So I'm curious--is this actually interesting to anyone else?

Would a video explaining all of this actually be useful?

Thank you,
-Chilton

2. You bet!!

It's about time I wrap my head around a couple of math concepts.

............. you funny.
I'd probly have a Brain Attack tryn to figure out some of this "Easy Math" you speak of.

but I would be interested in tutorials on the subject.

4. Definitely interesting, math is something I have slowly forgotten since I took the exam during the first years of my masters.

5. I think a video could be extremely helpful to grasp the concepts.

6. +1

7. Yep

8. Agreed

9. I believe there is a book on 3d math on amazon.

10. I'm pretty sure there's more than one awesome 3D math book out there. I just can't stand reading, these days. I blame TV, video games, and the Internet.

11. 3D maths...I might have to pick up my Hunt uni maths textbook that has gathered dust since 2004...

12. Alright, it sounds like this would be helpful, so I'll get to it.

Plus, I'd have them to look back on next week when I've forgotten all of it again

13. In the meantime, here is a site I bookmarked a while ago: http://chortle.ccsu.edu/vectorlesson...rIndex.html#00

14. Would definitely help me out -- this has been an area of real struggle for me ! +1
