[vtkusers] vtkTextureMapToPlane plane definition

[Christophe Franco]

I'm trying to display an image as a texture on a plane, using 
vtkTextureMapToPlane class. I'm using the following code :


vtkPNGReader* reader = vtkPNGReader::New();
reader->SetFileName("test.png"); // File in AmsaView directory
reader->Update();

vtkTextureMapToPlane* imageTexture = vtkTextureMapToPlane::New();
imageTexture->AutomaticPlaneGenerationOff();
imageTexture->SetInput(reader->GetOutput());
imageTexture->SetOrigin(0, 0, 0);
imageTexture->SetPoint1(0, 1, 0);
imageTexture->SetPoint2(0, 0, 1);

vtkDataSetMapper* imageMapper = vtkDataSetMapper::New();
imageMapper->SetInput(imageTexture->GetOutput());

vtkActor* actor = vtkActor::New();
actor->SetMapper(imageMapper);
actor->SetPosition(-110, -338, 785);



The result is, the image is displayed at the wanted position, but the 
plane is always along X-Y axes. No matter what values I use in the 
SetOrigin, SetPoint1 and SetPoint2 methods, the result is always exactly 
the same.

A also tried using the alternate method to define the plane with its 
origin and normal, and I still got the same result.

Is there something I am doing wrong ?
