Accessors

far

  • get far(): number

  • Gets the position of the OrthoProjection's far plane on the positive View-space Z-axis.

    Default value is 10000.0.

    returns New far ortho plane position.

    Returns number

  • set far(value): void

  • Sets the position of the OrthoProjection's far plane on the positive View-space Z-axis.

    Default value is 2000.0.

    Parameters

    • value: number

      New far ortho plane position.

    Returns void

inverseProjMatrix

near

  • get near(): number

  • Gets the position of the OrthoProjection's near plane on the positive View-space Z-axis.

    Default value is 0.1.

    returns New OrthoProjection near plane position.

    Returns number

  • set near(value): void

  • Sets the position of the OrthoProjection's near plane on the positive View-space Z-axis.

    Parameters

    • value: number

      New OrthoProjection near plane position.

    Returns void

projMatrix

  • get projMatrix(): FloatArrayParam

  • Gets the OrthoProjection's projection transform matrix.

    Default value is [1, 0, 0, 0, 0, 1, 0, 0, 0, 0, 1, 0, 0, 0, 0, 1].

    Returns FloatArrayParam

    The OrthoProjection's projection matrix.

scale

  • get scale(): number

  • Gets scale factor for this OrthoProjection's extents on X and Y axis.

    Clamps to minimum value of ````0.01```.

    Default value is 1.0

    returns New OrthoProjection scale value.

    Returns number
