# This example demonstrates the use of vtkAssembly. In an assembly, the motion
|
||
|
|
# of one actor affects the position of other actors.
|

|
|
|
||
|
|
#
|
||
|
|
# First we include the VTK Tcl packages which will make available
|
||
|
|
# all of the vtk commands to Tcl
|
||

|
||
|
|
package require vtk

# Create four parts: a top level assembly (in this case, a vtkCylinder)
|
||
|
|
# and three primitives (using vtkSphereSource, vtkCubeSource, and
|
||
|
|
# vtkConeSource). Set up mappers and actors for each part of the assembly to
|
||
|
|
# carry information about material properties and associated geometry.
