2D Layer

2D Layer

The following layer type can render 2D contents on top of another layer:

• 2DOverlay Renderer (type is 2dOverlay)

Input

• The input1 parameter is the background Layer where the 2D Layer renders on top of.

• If input1 is not specified, then the 2D Layer renders on top of a black background.

Camera

• The camera is required only to render 2DLabels.

• The extra camera is required when making stereo rendering without using code paths (such as Oculus or OpenVR) that automatically handle the camera. For example, during a DualHead viewport rendering, the extra camera is used as the Mono Camera. This is the camera from which the Stereo Cameras are derived.

• If the extra camera is required but not specified, the camera value is used.

Code example

This is an example of 2DOverlay renderer that uses a 2DLayer created inside the code.

<Layer name="SomeName" type="2dOverlay">

<layer2DName value="MainLayer"/>

<!-- name of the 2DLayer created by the code (note that the <Layer> node and the "code 2DLayer" are different things) -->

<input1 value="SourceLayerName"/>

<!-- some Layers need an input in order to be rendered, in this case the input is the name of another Layer -->

<cameraName value="Camera001"/>

<!-- it's not mandatory, can be also specified by the code -->

<extraCameraName value="Camera001"/> <!-- it's not mandatory, can be also specified by the code -->

</Layer>
