I''m making my own simple software 3D engine. I am now working on the transformations. I know how to transform my models to world space. But how do I transform to viewspace. I have heard something about you should take the inverse of the world matrix or something. Is this true? And how does that really work: do you multiply a vertex with that inverse or what? Please help me with this as this is part of my school work and I am supposed to hand this in in just two weeks!
