dot product
This term is a technical mathematical operation used primarily in linear algebra and physics. It describes a specific way of multiplying two vectors that results in a single scalar number rather than another vector, which distinguishes it from the cross product.
In practical application, the dot product is frequently used to determine the angle between two vectors or to check for orthogonality. If the dot product of two non-zero vectors is zero, they are perpendicular to each other.
Meanings
Examples
Calculate the dot product of these two vectors to find the angle between them.
The dot product is used here to determine if the vectors are perpendicular.
I forgot how to compute the dot product for three dimensional space.
In physics, work is defined as the dot product of force and displacement.
We can use the dot product to project one vector onto another.
The shader calculates the dot product of the light vector and the surface normal.
Wait, does the dot product result in a scalar or a vector?
The dot product of two unit vectors is simply the cosine of the angle between them.
