Syntax

'Declaration
Public Shared Function BoxBoundProbe ( _
    min As Vector3, _

)

public:
static bool BoxBoundProbe (
    Vector3 min, 
    Vector3 max, 
    Vector3 rayPosition, 
    Vector3 rayDirection
)

public static boolean BoxBoundProbe (
    Vector3 min, 
    Vector3 max, 
    Vector3 rayPosition, 
    Vector3 rayDirection
)

public static function BoxBoundProbe (
    min : Vector3, 
    max : Vector3, 
    rayPosition : Vector3, 
    rayDirection : Vector3
) : boolean

Parameters

min
A Vector3 structure that describes the lower-left corner of the bounding box.

max
A Vector3 structure that describes the upper-right corner of the bounding box.

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 bounding box; otherwise, false.

Remarks

The BoxBoundProbe method determines whether the ray intersects the volume of the bounding box, not just the surface of the box.

The values passed to BoxBoundProbe are xmin, xmax, ymin, ymax, zmin, and zmax. Thus, the following defines the corners of the bounding box.

xmax, ymax, zmax

xmax, ymax, zmin

xmax, ymin, zmax

xmax, ymin, zmin

xmin, ymax, zmax

xmin, ymax, zmin

xmin, ymin, zmax

xmin, ymin, zmin

The depth of the bounding box is zmax - zmin in the z direction; ymax - ymin in the y direction, and xmax - xmin in the x direction. For example, with the following minimum and maximum vectors, min (-1, -1, -1) and max (1, 1, 1), the bounding box is defined as follows.

1, 1, 1

1, 1, -1

1, -1, 1

1, -1, -1

1, 1, 1

-1, 1, -1

-1, -1, 1

-1, -1, -1
