D3DX8.ComputeBoundingSphere

Computes a bounding sphere.

object.ComputeBoundingSphere( _ 
    PointsFVF As Any, _ 
    NumVertices As Long, _ 
    FVF As Long, _ 
    Center As D3DVECTOR, _ 
    RadiusArray As Single)

Parts

object: Object expression that resolves to a D3DX8 object.
PointsFVF: Buffer containing the vertex data around which to calculate the bounding sphere.
NumVertices: Number of vertices.
FVF: Combination of flexible vertex format flags that describes the vertex format.
Center: D3DVECTOR type, defining the coordinate center of the returned bounding sphere.
RadiusArray: Radius of the returned bounding sphere.

Error Codes

If the method fails, an error is raised and Err.Number can be set to D3DERR_INVALIDCALL.
