[vtkusers] Seams in textures

[Thompson, David C]

A few weeks ago, texture edge clamping was added to vtkTexture. If
you are using the CVS head of VTK (as opposed to a stable release),
you might try EdgeClampOn() + RepeatOff() on your texture.

Subject: [vtkusers] Seams in textures

Hi,

I applied a cylindrical texture mapping to a polydata in order to render
a texturized object. So far it works quite well but at the border
between the texture coordinates 1.0 and 0.0 there is some stragne
behavior. The class vtkTextureMapToCylinder calls this "seam" and tries
to solve this by adding a mirrored instance of the texture. But in my
case I neet to apply an exact texture without any mirroring and
duplicating. Does VTK provide any way of solving this issue? Or do I
have to accept this as a feature of VTK?
