Module Brr_canvas.Matrix4Source

4x4 matrices.

Sourcetype t

The type for DomMatrixReadOnly objects.

Sourceval is_2d : t -> bool

is_2d m is true iff the matrix was initialized as 2D matrix.

Sourceval is_identity : t -> bool

is_identity m is true iff the matrix is the identity matrix.

Sourceval inverse : t -> t

inverse m is m's inverse.

Sourceval multiply : t -> t -> t

multiply m m' multiplies m by m'.

Typed array conversions

In arrays matrix elements are stored in column-major order.

Sourceval to_float32_array : t -> Brr.Tarray.float32
Sourceval of_float32_array : Brr.Tarray.float32 -> t
Sourceval to_float64_array : t -> Brr.Tarray.float64
Sourceval of_float64_array : Brr.Tarray.float64 -> t
