After some months in silence, I am here again!
From today my second App is available at the Windows Store. Its name is 3DC OBJViewer. It is a simple 3D viewer.
The App is free and it contains a banner advertisement (only one! Let me put that!).
In this first version, you can load only objects in Wavfront format (.OBJ). It is not excluded that some other formats will be added in the future.

For more information about the App, you can visit the page 3DC OBJViewer.
