Hello I'm new to this forum but in desperate need for some help so I thought I'd give it a try here.
Your eye is at (4,0,0). You are looking at a triangular plate whose verticies are (1,0,1), (1,1,0), and (-2,2,2). The line segment from (1,0,0) to (0,2,2) goes through the plate. What portion of this line is hidden from view by the plate?
ok so far I have found:
-The equation of the plane that the plate is on which I got -3x+3y-3z-6=0
-parametric equations of the line segment and got x=1-t, y=2t, and z=2t
-then I plugged the parametric equation values for x,y, and z into the plane equation to solve for t to result in the values for x,y, and z of the point of intersection (of the plate and line segment) and got (-2,3,3)
now from here I am lost on how to get the hidden part of the line segment. any help is appreciated
