Consider the infinite line, L in 2D consisting of all points p such that p.[0.3511 0.9263] = 6. Find the point on the line closest to (10,20). Find the point on the line closest to (4,3). Find the distance from the line to both of these points.
Hi, I was reading the book 3D Maths Primer for Graphics and Game Development. The book mention about 2 formulas but I don't know how to apply them.
Signed distance = d-q.n
q' = q + (d-q.n)n
for any point q, the point q' that is the closest point on L to q.
This is what I have tried,
Since the lines are parallel then the normal are the same so
q' = q + (6 - q(0.3511 0.9263))(0.3511 0.9263)
I'm stuck here.
