Help! I'm not very mathy, I'm doing a programming course at University, and this semester I have a Maths and Physics for Games subject. My lecturers aren't very helpful, we ask for examples and they get mad, we ask them to provide solutions for us to check our answers against and they get mad. So yeah, with a teaching strategy akin to Profesor Umbridge I'm pretty lost.
Anyway, I desperately need to understand how to use the generalised and parameterised plane equations, so that I can complete this assignment by sunday and not fail.
I understand the parameterized one a little bit; a plane is an origin point plus two arbitrarily scaled vectors, the only question on planes I've been able to answer for my assignment was to develop the plane equation from three given points...
P(s,t) = P0+s(P1-P0)+t(P1-P0)
= P0 +su+tv
Mainly I need someone to help me out with the generalised equation because I don't understand what anything represents and therefore how to find out other things from it, like if two planes are parallel, and how to find the perpendicular vector etc.
So any examples or explanations on...
...you can give me would be greatly appreciated!!
