This paper has very many bugs in its reproduction, especially in Win systems. It is therefore highly recommended to deploy it step by step in LINUX with reference to the original installation requirements, in particular, you should open the requirements file and install the requirements library step by step. However, after recent maintenance by the author, it should be much better. The last point to note is about Pyglt, which should be installed around version 1.5.0 for this task to work properly. Some additions, optimizations and modifications to the source code base based on the VIBE paper reproduction
On the other hand, to achieve this effect, a new renderer was rewritten in Render and called in the demo.
