• COMPOSITION_LAYER_UNPREMULTIPLIED_ALPHA_BIT — Indicates the texture color channels have not been premultiplied by the texture alpha channel.

XrEnvironmentBlendMode - Environment blend modes Enumerant Descriptions

• ENVIRONMENT_BLEND_MODE_OPAQUE. The composition layers will be displayed with no view of the physical world behind them. The composited image will be interpreted as an RGB image, ignoring the composited alpha channel. This is the typical mode for VR experiences, although this mode can also be supported on devices that support video passthrough.
• ENVIRONMENT_BLEND_MODE_ADDITIVE. The composition layers will be additively blended with the real world behind the display. The composited image will be interpreted as an RGB image, ignoring the composited alpha channel during the additive blending. This will cause black composited pixels to appear transparent. This is the typical mode for an AR experience on a see-through headset with an additive display, although this mode can also be supported on devices that support video passthrough.
• ENVIRONMENT_BLEND_MODE_ALPHA_BLEND. The composition layers will be alpha-blended with the real world behind the display. The composited image will be interpreted as an RGBA image, with the composited alpha channel determining each pixel’s level of blending with the real world behind the display. This is the typical mode for an AR experience on a phone or headset that supports video passthrough.

XrSpaceLocationFlagBits - Space location flags Description

The flag bits have the following meanings: Flag Descriptions

• SPACE_LOCATION_ORIENTATION_VALID_BIT indicates that the pose field’s orientation field contains valid data. For a space location tracking a device with its own inertial tracking, SPACE_LOCATION_ORIENTATION_TRACKED_BIT should remain set when this bit is set. Applications must not read the pose field’s orientation if this flag is unset.
• SPACE_LOCATION_POSITION_VALID_BIT indicates that the pose field’s position field contains valid data. When a space location loses tracking, runtimes should continue to provide valid but untracked position values that are inferred or last-known, so long as it’s still meaningful for the application to use that position, clearing SPACE_LOCATION_POSITION_TRACKED_BIT until positional tracking is recovered. Applications must not read the pose field’s position if this flag is unset.
• SPACE_LOCATION_ORIENTATION_TRACKED_BIT indicates that the pose field’s orientation field represents an actively tracked orientation. For a space location tracking a device with its own inertial tracking, this bit should remain set when SPACE_LOCATION_ORIENTATION_VALID_BIT is set. For a space location tracking an object whose orientation is no longer known during tracking loss (e.g. an observed QR code), runtimes should continue to provide valid but untracked orientation values, so long as it’s still meaningful for the application to use that orientation.
• SPACE_LOCATION_POSITION_TRACKED_BIT indicates that the pose field’s position field represents an actively tracked position. When a space location loses tracking, runtimes should continue to provide valid but untracked position values that are inferred or last-known, e.g. based on neck model updates, inertial dead reckoning, or a last-known position, so long as it’s still meaningful for the application to use that position.

When a view loses tracking, runtimes should continue to provide valid but untracked view position values that are inferred or last-known, e.g. based on neck model updates, inertial dead reckoning, or a last-known position, so long as it’s still meaningful for the application to render content using that position.
