C Specification

A rectangle with floating-point values is defined by the structure:

// Provided by XR_VERSION_1_0
typedef struct XrRect2Df {
    XrOffset2Df    offset;
    XrExtent2Df    extent;
} XrRect2Df;

Members

Member Descriptions

  • offset is the XrOffset2Df specifying the rectangle offset.

  • extent is the XrExtent2Df specifying the rectangle extent.

Description

This structure is used for component values that may be real numbers, represented with single-precision floating point.

The offset is the position of the rectangle corner with minimum value coordinates. The other three corners are computed by adding the XrExtent2Df::width to the x offset, XrExtent2Df::height to the y offset, or both.
