Link to the Unity project source code - compressed file size is 4.74GB and could not be uploaded to Kos. https://drive.google.com/file/d/1Dl6RuGq_FAzdr8qUnbL3CquQzKVRow95/view?usp=sharing The Unity source code does not cointain builds, demos are meant to be used on the websites. The Unity source code contains whole Unity project. Scenes, prefabs, scripts are inside assets folder. unity_scripts.zip contains scripts that are identical to the scripts which can be found in the Unity source code, I put them here also separately to make them more accessible. imgs.zip - Contains six FullHD images one image of each of the six demos. web_pages.zip - This zip was split into five parts web_pages[.zip .z01 .z02 .z03 .z04] and contains the source code of the web pages.
