I have created another public repository for graphics town to give you more examples of objects.
Right now, there is only one new object: a shiny sphere that has a dynamic reflection map.
You can see the repository at: https://github.com/CS559/S19-GraphicsTownExamples
and even try out the updated graphics town at: https://cs559.github.io/S19-GraphicsTownExamples/
(you are allowed to use the examples in your Assignments – if you give proper attribution)
