Determines whether a ray intersects the volume of a sphere's bounding box.

Namespace: Microsoft.WindowsMobile.DirectX.Direct3D
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
)

static member SphereBoundProbe : 
        center:Vector3 * 
        radius:float32 * 
        rayPosition:Vector3 * 
        rayDirection:Vector3 -> bool

Parameters

center
Type: Microsoft.WindowsMobile.DirectX.Vector3
A Vector3 structure that specifies the center coordinate of the sphere.

radius
Type: System.Single
The radius of the sphere.

rayPosition
Type: Microsoft.WindowsMobile.DirectX.Vector3
A Vector3 structure that specifies the origin coordinate of the ray.

rayDirection
Type: Microsoft.WindowsMobile.DirectX.Vector3
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

Type: System.Boolean
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, and not just its surface.
