C Specification

A two-dimensional floating-point extent is defined by the structure:

// Provided by XR_VERSION_1_0
typedef struct XrExtent2Df {
    float    width;
    float    height;
} XrExtent2Df;

Members

Member Descriptions

  • width is the floating-point width of the extent.

  • height is the floating-point height of the extent.

Description

This structure is used for component values that may be real numbers, represented with single-precision floating point. For representing extents in discrete values, such as texels, the integer variant XrExtent2Di is used instead.

If used to represent physical distances, values must be in meters.

The width and height value must be non-negative.
