C Specification

The XrPassthroughColorMapInterpolatedLutMETA structure is defined as:

// Provided by XR_META_passthrough_color_lut
typedef struct XrPassthroughColorMapInterpolatedLutMETA {
    XrStructureType              type;
    const void*                  next;
    XrPassthroughColorLutMETA    sourceColorLut;
    XrPassthroughColorLutMETA    targetColorLut;
    float                        weight;
} XrPassthroughColorMapInterpolatedLutMETA;

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.

  • sourceColorLut is the initial XrPassthroughColorLutMETA.

  • targetColorLut is the final XrPassthroughColorLutMETA.

  • weight is a factor in the range [0, 1] which defines the linear blend between the initial and the final color LUT.

Description

XrPassthroughColorMapInterpolatedLutMETA lets applications apply the interpolation between two color LUTs to a passthrough layer. Applications may use this feature to smoothly transition between two color LUTs. Other Passthrough style elements (such as edges) must not be affected by color LUTs.

The blend between sourceColorLut and targetColorLut is computed as (1 - weight) * sourceColorLut [Cin] + weight * targetColorLut [Cin].

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