Project one vector onto another — the vector and scalar projection. Enter both vectors.
Vector Projection
—
A onto B.Usage Tip
Projection splits a vector into a part along another and a part perpendicular to it — the basis of many physics and graphics calculations.
THE MATH
proj = ((A · B) ÷ (B · B)) × B
scalar projection = (A · B) ÷ |B|
scalar projection = (A · B) ÷ |B|
The projection of A onto B is the part of A that points along B — the shadow A casts on B’s direction.
The scalar projection is that shadow’s signed length.
The scalar projection is that shadow’s signed length.
Enter two vectors of equal length.
The vector projection lies along B; the scalar projection is its length.
You cannot project onto the zero vector.
