Module matrix

Matrix math types and functions.

Traits

Matrix

Matrix trait which defines the basic operations that can be performed on a matrix. Lambda currently implements this trait for f32 arrays of arrays for any size.

Functions

filled_matrix

Creates a new matrix with the given number of rows and columns, and fills it with the given value.

identity_matrix

Creates an identity matrix of the given size.

perspective_matrix

Creates a 4x4 perspective matrix given the fov in turns (unit between 0..2pi radians), aspect ratio, near clipping plane (also known as z_near), and far clipping plane (also known as z_far). Enforces that the matrix being created is square in both debug and release builds, but only enforces that the output matrix is 4x4 in debug builds.

rotate_matrix

Rotates the input matrix by the given number of turns around the given axis. The axis must be a unit vector and the turns must be in the range [0, 1). The rotation is counter-clockwise when looking down the axis.

submatrix

Obtain the submatrix of the input matrix starting from the given row & column.

translation_matrix

Creates a translation matrix with the given translation vector. The output vector

zeroed_matrix

Create a matrix of any size that is filled with zeros.
