About LinkBacksI know two points in 3D space:
{x1, y1, z1} and {x2, y2, z2}
How do I find the coordinates of a third point at y=y3 on a straight line through those two points?

If you know the value ofthen you can determine the value of r by solving the equation:
Once you know the value of r you can plug it into the equation of the line to calculate the missing coordinates of the point.
