I am a student from Malaysia and previously I learn mathematics in a different language (Malay). I had a lot of difficulty to understand mathematics in English. So is there any tutorial out there that teach basic mathematics. As long the mathematics are used in 3D concepts. (Not too complicated). I am more towards coding and not a mathematician :D. Just want to understand some of the concepts like collision detection. Please Help. I''m stuck on a tutorial here "Theory Practice". What is "linear equation"? How is it represented? What is "cubic or quadratic equation"? How does it looks like? From this we have: P1(t) = (x1 + 2t, y1 + 7t) P2(t) = (x2 - t, y2 + 2t) Further, R(t) = [(x1 + 2t) - (x2 - 2t)]2 + [(y1 + 2t) - (y2 + t)]2 = (x1 - x2 + 3t)2 + (y1 - y2 + 5t)2 = (x1 - x2)2 + (y1 - y2)2 + 3t(2x1 - 2x2 + 3t) + 5t(2y1 - 2y2 + 5t) = [32+52]t2 + 2[3(x1 - x2) + 5(y1 - y2)]t + [(x1 - x2)2 + (y1 - y2)2] "I think i did not touch much maths since 3 years ago, and my brain is DOWN!". Help needed please. Basic maths also preferrable. Thank you. Regards, Chua Wen Ching :D "Very new to games I think"

You can go and buy this book "Computer Graphics using Open GL 2nd Edition" by F.S.HILL,JR.

This book is great for people that want to know about computer graphics in OPENGL. This book also a textbook in UTM.

Linear Equations have no indicies or powers. Everything is to the power of 1.

2 to the power of 1 is 2, 2 to the power of 2 (2x2) is 4, 2 to the power of 3 (2x2x2) is 8 and so on. These are indicies or powers.

A linear equation is all in the power of 1 no squares, no cubes etc.

Linear
------

2x+3y=13

Quadratic
---------

__2
2x +3y=17

I’ve been reading 3D Math Primer for Graphics and Game Development. It starts simple with coordinate systems and moves through most of the 3D math you are likely to need including linear algebra.

There is also a good website that you might want to try:
www.mathworld.com
You can search or browse for what you are looking for and they give you a reasonably clear explanation.

http://www.sosmath.com/matrix/matrix.html <- Another Good math site.

Thanks yspotua.
