[vtkusers] Texture Mapping

[Sathya Krishnamurthy]

Ciao

it is not a straight forward solution texture mapping a 3ds file in vtk


i had a hack some time back..

i did somethink like this..

from renderwindow i went back to polydata and then assigned the texture
and then added the texture + polydata to the scene

may be somebody has better solution..

cheers

vtk3DSImporter mano
mano SetFileName "scocca.3ds"
mano SetRenderWindow renWin
# first create the 3Ds actor
mano Update


set actorlist [[mano GetRenderer] GetActors]

$actorlist InitTraversal

#get the polydata.. basically i do a 
# reverse engineering..

set thePolyData [[[$actorlist GetNextItem] GetMapper] GetInput]

# now read the bmp file..
vtkBMPReader pnmReader
  pnmReader SetFileName "cscs.bmp"

vtkTexture atext
  atext SetInput [pnmReader GetOutput]

vtkTextureMapToPlane ntext
  ntext SetInput $thePolyData
 
vtkDataSetMapper manoMapper
  manoMapper SetInput [ntext GetOutput]

vtkActor manoActor
  manoActor SetMapper manoMapper
  manoActor SetTexture atext

# Add the New Textured Top
ren1 AddActor manoActor

#may be you want to remove the old actor..
