C Specification

The XrPassthroughColorMapLutMETA structure is defined as:

// Provided by XR_META_passthrough_color_lut
typedef struct XrPassthroughColorMapLutMETA {
    XrStructureType              type;
    const void*                  next;
    XrPassthroughColorLutMETA    colorLut;
    float                        weight;
} XrPassthroughColorMapLutMETA;

Members

Member Descriptions

  • type is the XrStructureType of this structure.

  • next is NULL or a pointer to the next structure in a structure chain. No such structures are defined in core OpenXR or this extension.

  • colorLut is an XrPassthroughColorLutMETA.

  • weight is a factor in the range [0, 1] which defines the linear blend between the original and the mapped colors for the output color.

Description

XrPassthroughColorMapLutMETA lets applications apply a color LUT to a passthrough layer. Other Passthrough style elements (such as edges) must not be affected by color LUTs.

Applications may use weight to efficiently blend between the original colors and the mapped colors. The blend is computed as (1 - weight) * Cin + weight * colorLut [Cin].

XrPassthroughColorMapLutMETA is provided in the next chain of XrPassthroughStyleFB when calling xrPassthroughLayerSetStyleFB. Subsequent calls to xrPassthroughLayerSetStyleFB with XrPassthroughColorMapLutMETA in the next chain update the color LUT for that layer. Subsequent calls to xrPassthroughLayerSetStyleFB without this XrPassthroughColorMapLutMETA (or XrPassthroughColorMapInterpolatedLutMETA) in the next chain disable color LUTs for that layer.
