Hey,
Earlier I was pretty sure I understood the concept of World transformations - but now that I think about it more, it gets more confusing and more questions pop up.

I understand that you must move the world to move an object, but where are YOU viewing the world from? I think i'm viewing from point 0,0,0 -

Can someone clarify please (3D transformations)

Thanks

No, but I move around my objects positions using Device.Transform.View = Matrix.LH(Position, Target,Up),

but is that possible :)!!! Viewing the world from a camera object?

That's exactly what I want to accomplsih, can I view the world from a different position, or must I do it the usual way and translate objects relative to you/

You can move the view while leaving other objects in the same place. You just have to build a new View matrix everytime you wish to move the "camera" (which refers to the View transformation). You don't have to be viewing the world from 0, 0, 0.
 
Ahah, I think I figured it out:

World transformations are done to 'move' the object.
View tranformations are done to change your position around in the world.

Please let me know if this is correct,
Pent
