Struct ovr_sys::ovrLayerQuad

#[repr(C)]
pub struct ovrLayerQuad {
    pub _align: [isize; 0],
    pub Header: ovrLayerHeader,
    pub ColorTexture: ovrTextureSwapChain,
    pub Viewport: ovrRecti,
    pub QuadPoseCenter: ovrPosef,
    pub QuadSize: ovrVector2f,
}

Describes a layer of Quad type, which is a single quad in world or viewer space.

It is used for ovrLayerType_Quad. This type of layer represents a single object placed in the world and not a stereo view of the world itself.

A typical use of ovrLayerType_Quad is to draw a television screen in a room that for some reason is more convenient to draw as a layer than as part of the main view in layer 0. For example, it could implement a 3D popup GUI that is drawn at a higher resolution than layer 0 to improve fidelity of the GUI.

Quad layers are visible from both sides; they are not back-face culled.

Fields

_align: [isize; 0]

Header: ovrLayerHeader

Header.Type must be ovrLayerType_Quad.

ColorTexture: ovrTextureSwapChain

Contains a single image, never with any stereo view.

Viewport: ovrRecti

Specifies the ColorTexture sub-rect UV coordinates.

QuadPoseCenter: ovrPosef

Specifies the orientation and position of the center point of a Quad layer type.

The supplied direction is the vector perpendicular to the quad.

The position is in real-world meters (not the application's virtual world, the physical world the user is in) and is relative to the "zero" position set by ovr_RecenterTrackingOrigin unless the ovrLayerFlag_HeadLocked flag is used.

QuadSize: ovrVector2f

Width and height (respectively) of the quad in meters.
