# This simple example shows how to do basic texture mapping.
|
|
#
|
|
# We start off by loading some Tcl modules. One is the basic VTK library;
|
|
# the other is a package for rendering.
|
|
#
|
|
package require vtk
|
|
package require vtkinteraction
|
|
|
|
# Load in the texture map. A texture is any unsigned char image. If it
|
|
# is not of this type, you will have to map it through a lookup table
|
|
# or by using vtkImageShiftScale.
|
|

# Create a plane source and actor. The vtkPlanesSource generates
|
|
# texture coordinates.
