C Specification

An XrSceneFrustumBoundMSFT structure describes the pose, field of view, and far distance of a frustum bounds.

// Provided by XR_MSFT_scene_understanding
typedef struct XrSceneFrustumBoundMSFT {
    XrPosef    pose;
    XrFovf     fov;
    float      farDistance;
} XrSceneFrustumBoundMSFT;

Members

Member Descriptions

  • pose is an XrPosef defining the position and orientation of the tip of the frustum bound within the reference frame of the corresponding XrSceneBoundsMSFT::space.

  • fov is an XrFovf for the four sides of the frustum bound where XrFovf::angleLeft and XrFovf::angleRight are along the X axis and XrFovf::angleUp and XrFovf::angleDown are along the Y axis of the frustum bound space.

  • farDistance is the positive distance of the far plane of the frustum bound along the -Z direction of the frustum bound space.

Description

The runtime must return XR_ERROR_VALIDATION_FAILURE if farDistance is less than or equal to zero. The runtime must return XR_ERROR_VALIDATION_FAILURE if the fov angles are not between between -π/2 and π/2 exclusively.
