Matrix4
new Matrix4(elements?)
THREE: THREE.Matrix4
Column-major 4×4 matrix backed by a Float32Array. Initialises to identity when called with no arguments.
Differs from THREE.js
multiply() is named mul(). makePerspective takes fov in radians (not degrees) and has a different parameter order than THREE.
Properties
| Name | Type | Description |
|---|---|---|
elements | Float32Array | Flat 16-element column-major storage (read-only accessor). |
Methods
| Method | Description |
|---|---|
identity(): this | Resets to the identity matrix. |
copy(m: Matrix4): this | Copies elements from another Matrix4. |
clone(): Matrix4 | Returns a new Matrix4 with the same elements. |
compose(position: Vector3, q: Quaternion, scale: Vector3): this | Builds a TRS matrix from position, quaternion, and scale. |
decompose(position: Vector3, q: Quaternion, scale: Vector3): this | Extracts position, quaternion, and scale from this matrix. |
invert(): this | Inverts the matrix in place. |
mul(m: Matrix4): this | Post-multiplies this matrix by m. |
mulMatrices(a: Matrix4, b: Matrix4): this | Sets this to a × b. |
makePerspective(fov: number, aspect: number, near: number, far: number): this | Builds a perspective projection matrix from radians fov. |
makeOrthographic(left, right, top, bottom, near, far): this | Builds an orthographic projection matrix. |
