Assembly: Microsoft.WindowsMobile.DirectX (in microsoft.windowsmobile.directx.dll)

Syntax

'Declaration
Public Shared Function SphereBoundProbe ( _
    center As Vector3, _
    radius As Single, _
    rayPosition As Vector3, _
    rayDirection As Vector3 _
) As Boolean
'Usage
Dim center As Vector3
Dim radius As Single
Dim rayPosition As Vector3
Dim rayDirection As Vector3
Dim returnValue As Boolean

returnValue = Geometry.SphereBoundProbe(center, radius, rayPosition, rayDirection)

public static bool SphereBoundProbe (
    Vector3 center,
    float radius,
    Vector3 rayPosition,
    Vector3 rayDirection
)

public:
static bool SphereBoundProbe (
    Vector3 center, 
    float radius, 
    Vector3 rayPosition, 
    Vector3 rayDirection
)

public static boolean SphereBoundProbe (
    Vector3 center, 
    float radius, 
    Vector3 rayPosition, 
    Vector3 rayDirection
)

public static function SphereBoundProbe (
    center : Vector3, 
    radius : float, 
    rayPosition : Vector3, 
    rayDirection : Vector3
) : boolean

Parameters

center
A Vector3 structure that specifies the center coordinate of the sphere.

radius
The radius of the sphere.

rayPosition
A Vector3 structure that specifies the origin coordinate of the ray.

rayDirection
A Vector3 structure that specifies the direction of the ray. This vector should not be (0,0,0), but does not need to be normalized.

Return Value

true if the ray intersects the volume of the sphere's bounding box; otherwise, false.

Remarks

The SphereBoundProbe method determines whether the ray intersects the volume of the sphere, not just its surface.
