Hi Vincent,<br><br>Couple of things you might want to look into-<br><br>1) Validity time of the transform that is set to the MeshObject.<br>2) View Camera parameters<br><br>-Andinet<br><br><div><span class="gmail_quote">On 10/24/07,

Hi igstk-users,<br><br>I'm currently trying to apply a texture on a surface.<br>So I developed a new class called TexturedMeshObjectRepresentation which<br>inherits MeshObjectRepresentation.<br>This class does the same thing than its super class, but I added this
<br>code at the end of the CreateActors method :<br><br>> if( m_TextureFileNameIsSet )<br>> {<br>> vtkPNMReader *pnmReader = vtkPNMReader::New();<br>> pnmReader->SetFileName(m_TextureFileName.c_str());
<br>><br>> if(! pnmReader->CanReadFile(m_TextureFileName.c_str()))<br>> {<br>> igstkLogMacro( CRITICAL,"Unable to read texture file\n" );<br>> return ;<br>> }<br>>
<br>> vtkTexture* texture = vtkTexture::New();<br>> texture->SetInput( pnmReader->GetOutput() );<br>> texture->InterpolateOn();<br>><br>> meshActor->SetTexture(texture);<br>
> }<br>><br>> this->AddActor( meshActor );<br><br>where m_TextureFileName contains the name of the corresponding PNM file.<br><br>The resulting surface representation is black.<br>I tried to write a simple VTK executable in order to test this code, and
<br>it works correctly...<br><br>So does anyone know where can be the problem ?<br><br>Thank you and have a nice day !<br><br>--<br>Vincent Gratsac<br>----------------------------------------------------<br>Unité/Projet VisAGeS U746
