' This example creates a sphere, applies a lambert shader to it, prints out

' the list of connection points to that shader, connects the rounded 

' connection point to the toon shader and then prints the updated list.

				oSphere, "Christopher" )

' Convert the shader to a Shader object 

set oShader = oShader(0)

' Print lambert shader info 

printShaderInfo oShader

' For convenience, create a collection to hold the parameters

' to be disconnected (Surface and Shadow connection points).

set oCnxPoints = CreateObject( "XSI.Collection" )
