I'm trying to place a texture in a 3d object, using Visual Basic and WPF, but I'm not being able to do it.
If instead of an image I render a blue square, by replacing the line
mymodel3dgroup.Children.Add(New GeometryModel3D(mymesh, df))
for
mymodel3dgroup.Children.Add(New GeometryModel3D(mymesh, New DiffuseMaterial(Brushes.Blue)))
then I get a blue square. But what I need is to see the image, not just paint the object(s).
Can you please help?
My thanks in advanced
