Does anybody know which matrices and vectors should i use in 3dgs for the ones that are specified in other tools

I have:

vector Eye Position (World) - Which vector should i use in 3dgs?
vector Light Position (World) - Which one is that (maybe vecLight or VecSunDir)?
matrix Inverse World - which matrix is this in 3dgs?
matrix View Projection - i think this is matWorldViewProj but just to be sure.


I converted some shaders but i don't know which matrix to use. I see the effect on the model but the model is not where it's supposed to be, or you have to stand in a certain place to see it so i'm thinking this has something to do with the View matrix or vectors :?
