[vtkusers] Re: question on texture mapping

[Bruce Lamond]

Hi Ann,

do something like this:

get your .vtk model as vtkPoyData

vtkJPEGReader pic
        pic SetFileName "*.jpg"

vtkTexture tex
        tex SetInput [pic GetOutput]

vtkProjectedTexture pTex
        pTex SetInput [model GetOutput]
        pTex SetSRange 0 1
        pTex SetTRange 0 1
        pTex SetAspectRatio 0 0 0
        pTex SetFocalPoint 0 0 0
        pTex SetUp 0 1 0
        pTex SetPosition 0 0 0

(play around with the pTex settings to get the correct texture position)

vtkPolyDataMapper dMapper
        dMapper SetInput [pTex GetOutput]
vtkActor pTexActor
        pTexActor SetMapper dMapper
        pTexActor SetTexture tex

ren1 AddActor pTexActor
renWin Render
