Matri rices
- A matrix encodes transformations to be applied to a point.
- By multiplying such a matrix with a point, we apply the
transformation to the point.
- We can concatenate transformations stored in separate matrices into
a single matrix by multiplying the matrices.
- There’s a special matrix called an identity matrix.
