Link to an external texture file in stand-alone XAML representing a three-dimensional model

Question

I have a XAML file representing a three-dimensional model with textures.

I want the textures to be read from or in relation to the file.

I am reading a file using XamlReader, so I want the file to be offline.

I place textures using ImageBrush, which ImageSource is the synatx package URI.

When I use the 'siteoforigin' syntax, this only works if the texture file is next to the application. I want it next to Xaml, wherever it is.

I tried setting the current directory to the Xaml directory, but that did not help.

Not using the package syntax does not work, it just searches for a resource with that name.

How do I need to write a Xaml image source (or is there another way to place textures for a diffuse material brush?) So that this will work?

Answer 1

I solved this problem simply by preloading XAML into the memory stream, replacing the siteoforigin :, operators with the path from which xaml was placed, and then loading the model from the updated memory stream using XamlReader.Load

My models are probably a sketch export exported using my own built-in xaml plugin, although I modified it to export normals and, in particular, changed the model to the WPF coordinate system.
