So i have a normalized vector (ray), that is pointing somewhere. now i want to determine a 3d point on the ray, where y (up/down) is equal to zero. basically an intersection with a plane, on Y=0.
how would i do this?
Help, please. I cant find anything about getting the xyz coordinates of intersection between a line and a plane.
Here and here are links which treat about intersections. They don’t specifically deal about axis-aligned planes, but if you understand the reasoning, that will certainly help you.
One other thing that might help you. From the plane equation ax+by+cz+d=0, (a,b,c) are the 3 components of the normal to this plane.
