IVROverlay::ComputeOverlayIntersection

bool ComputeOverlayIntersection( VROverlayHandle_t ulOverlayHandle, const VROverlayIntersectionParams_t *pParams, VROverlayIntersectionResults_t *pResults )

Computes the overlay-space pixel coordinates of where the ray intersects the overlay. Returns false if there is no intersection.

• VROverlayHandle_t ulOverlayHandle - Handle of the overlay to test intersection with
• const VROverlayIntersectionParams_t *pParams - The ray to test for intersection
• VROverlayIntersectionResults_t *pResults - The details of the results

Description

Intersections are tested using these parameter blocks:

struct VROverlayIntersectionParams_t
{
	HmdVector3_t vSource;
	HmdVector3_t vDirection;
	TrackingUniverseOrigin eOrigin;
};

struct VROverlayIntersectionResults_t
{
	HmdVector3_t vPoint;
	HmdVector3_t vNormal;
	HmdVector2_t vUVs;
	float fDistance;
};
