isDummy

isEqual

  • isEqual(mat, delta?): boolean

  • Checks if this matrix is approximately equal to another matrix.

    Parameters

    • mat: IMatrix33

      Matrix to compare against

    • Optionaldelta: number

      Optional tolerance for comparison (default: small epsilon)

    Returns boolean

    True if matrices are approximately equal

isStrictEqual

  • isStrictEqual(mat): boolean

  • Checks if this matrix is strictly equal to another matrix.

    Parameters

    Returns boolean

    True if matrices are exactly equal

isTheSourceSame

  • isTheSourceSame(arrayBuffer): boolean

  • Checks if the internal array buffer is the same as the provided one.

    Parameters

    • arrayBuffer: ArrayBuffer

      Array buffer to compare against

    Returns boolean

    True if the source is the same

toString

toStringApproximately

v
