The exercises designed by Mr. de Vries are coded in C++. I have recoded some of them in Kotlin and adapted them to the Android system. Here is a link to the Github repo where a selection of the exercises are completed.
The project does not use any supporting graphics libraries aside what is built into the Android Framework. The math support is provided by the Rajawali Math modules. The modules are converted to kotlin and are located in the java/org/rejawali3d subtree.
