I'm doing line plane intersection, and have come across an un-referenced variable or constant in the tutorial I'm following.
One of the formulae given is this:
t = N dot (p2 – p0)
N dot V
The variable I'm stuck with is V
. Can someone tell me what V
is and how I'd go about finding it?
For more info on that formula, please see the link given in the first para.
Thanks,
James
