Function ortho

  • ortho(out, left, right, bottom, top, near, far): mat4

  • Generates a orthogonal projection matrix with the given bounds. The near/far clip planes correspond to a normalized device coordinate Z range of [-1, 1], which matches WebGL/OpenGL's clip volume.

    Parameters

    • out: mat4

      mat4 frustum matrix will be written into

    • left: number

      Left bound of the frustum

    • right: number

      Right bound of the frustum

    • bottom: number

      Bottom bound of the frustum

    • top: number

      Top bound of the frustum

    • near: number

      Near bound of the frustum

    • far: number

      Far bound of the frustum

    Returns mat4
