Details

Detailed Description

This will take full advantage of the display resolution and avoid double resampling of the texture.

We support 3 types of Overlay shapes right now

Quad : This is most common overlay type , you render a quad in Timewarp space.

Cylinder: [Mobile Only][Experimental], Display overlay as partial surface of a cylinder

The cylinder's center will be your game object's center

We encoded the cylinder's parameters in transform.scale, **[scale.z] is the radius of the cylinder **[scale.y] is the height of the cylinder **[scale.x] is the length of the arc of cylinder

Limitations **Only the half of the cylinder can be displayed, which means the arc angle has to be smaller than 180 degree, [scale.x] / [scale.z] <= PI **Your camera has to be inside of the inscribed sphere of the cylinder, the overlay will be faded out automatically when the camera is close to the inscribed sphere's surface. **Translation only works correctly with vrDriver 1.04 or above

Cubemap: Display overlay as a cube map

OffcenterCubemap: [Mobile Only] Display overlay as a cube map with a texture coordinate offset

The actually sampling will looks like [color = texture(cubeLayerSampler, normalize(direction) + offset)] instead of [color = texture( cubeLayerSampler, direction )]

The extra center offset can be feed from transform.position

Note: if transform.position's magnitude is greater than 1, which will cause some cube map pixel always invisible Which is usually not what people wanted, we don't kill the ability for developer to do so here, but will warn out.

Equirect: Display overlay as a 360-degree equirectangular skybox.

Fields

OverlayType OVROverlay.currentOverlayType
Specify overlay's type.

bool OVROverlay.isDynamic
If true, the texture's content is copied to the compositor each frame.

bool OVROverlay.isExternalSurface
If true, the layer will be created as an external surface. externalSurfaceObject contains the Surface object. It's effective only on Android.

int OVROverlay.externalSurfaceWidth
The width which will be used to create the external surface. It's effective only on Android.

int OVROverlay.externalSurfaceHeight
The height which will be used to create the external surface. It's effective only on Android.

int OVROverlay.compositionDepth
The compositionDepth defines the order of the OVROverlays in composition. The overlay/underlay with smaller compositionDepth would be composited in the front of the overlay/underlay with larger compositionDepth.

OverlayShape OVROverlay.currentOverlayShape
Specify overlay's shape.

Texture [] OVROverlay.textures
The left- and right-eye Textures to show in the layer. Note: If you need to change the texture on a per-frame basis, please use OverrideOverlayTextureInfo(..) to avoid caching issues.
