D3DXSphereBoundProbe function (D3DX9Mesh.h)
Note
The D3DX utility library is deprecated. We recommend that you use DirectXMath instead.
Determines if a ray intersects the volume of a sphere's bounding box.
Syntax
BOOL D3DXSphereBoundProbe(
_In_ const D3DXVECTOR3 *pCenter,
_In_ FLOAT Radius,
_In_ const D3DXVECTOR3 *pRayPosition,
_In_ const D3DXVECTOR3 *pRayDirection
);
Parameters
-
pCenter [in]
-
Type: const D3DXVECTOR3*
Pointer to a D3DXVECTOR3 structure, specifying the center coordinate of the sphere.
-
Radius [in]
-
Type: FLOAT
Radius of the sphere.
-
pRayPosition [in]
-
Type: const D3DXVECTOR3*
Pointer to a D3DXVECTOR3 structure, specifying the origin coordinate of the ray.
-
pRayDirection [in]
-
Type: const D3DXVECTOR3*
Pointer to a D3DXVECTOR3 structure, specifying the direction of the ray. This vector should not be (0,0,0) but does not need to be normalized.
Return value
Type: BOOL
Returns TRUE if the ray intersects the volume of the sphere's bounding box. Otherwise, returns FALSE.
Remarks
D3DXSphereBoundProbe determines if the ray intersects the volume of the sphere's bounding box, not just the surface of the sphere.
