Vectors

[NupaulMiller]

Sometimes I have trouble visualizing how vectors actually work.

When we get the Look Direction vector, is it a Vector that’s relative to the absolute position of the camera in the world?
So as the camera moves in each frame we are saying give me a vector that represents from where the camera is to one unit away.

Thanks!

Edit: Also why cant Look Direction be used as the Start Location?

It’s not a position. It’s a unit vector which is a vector which has a length of 1. Meaning it’s just a direction and no magnitude.

To where the camera is looking.

Because it’s a direction and not a location.
