My name is Eduardo and I´m from Portugal. Currently I´m doing a project in which I need to calculate the intersection point of a vector with a plane.
The equation of the plane is Z=0, and the vector is a column with 3 elements (something like
I googled a little bit and I found this site:
This seems to be what I´m looking for. However, my doubt arises at the first the step needed to parametrize the vector!
The site says:
"A ray is defined by: R0 = [X0, Y0, Z0]
Rd = [Xd, Yd, Zd]"
I searched the net and I understood that R0 is a point at the origin, and Rd is a point on the vector, but how can I atribute values to X0 , Y0, Z0, Xd, Yd, Zd ? How can I invent them??????
Unfortunately I´m not keen on maths and I´m facing this doubt despite my effort. I´m sure that you can help me . Do you?
and thanks in advance for your time!
