Ik heb een probleempje met color mapping in vtk... In plaats van
verschillende kleuren krijg ik een volledig rood object...
Ik weet niet goed wat ik fout doe (ben nog maar zeer recent met vtk
begonnen)...
Kan iemand me helpen?
Thnx a lot!

Dit is (een deel van) de code:



vtkUnstructuredGrid dataSet
vtkPoints pts
vtkFloatArray scalars

.........

while { ![eof $file] } {
   # Read a line from the file and analyse it.
   scan $line "%f %f %f %f" v1 v2 v3 v4
   set line [gets $file]

   pts InsertNextPoint $v1 $v2 $v3
   # 0 < v4 < 250
   scalars InsertNextValue $v4
}

dataSet SetPoints pts
[dataSet GetPointData] SetScalars scalars

.........

vtkGaussianSplatter popSplatter
popSplatter SetInput dataSet
popSplatter SetSampleDimensions 50 50 50
popSplatter SetRadius 0.05
popSplatter ScalarWarpingOff

vtkContourFilter popSurface
popSurface SetInput [popSplatter GetOutput]
popSurface SetValue 0 0.01

vtkPolyDataMapper popMapper
popMapper SetInput [popSurface GetOutput]
popMapper ScalarVisibilityOn

vtkActor actor
actor SetMapper popMapper
[actor GetProperty] SetOpacity 0.3
[actor GetProperty] SetColor .9 .9 .9

.........

mvg,
