How to make a 3D shape on a web page

Question

Java

I made a website that generates zadi for a child in mathematics. Now my senior has to prepare for a geometry test and I want to add all sorts of problems with pyramids and prisms to the site.
How to display them on a web page?

In principle, I do not need something dynamic. I want to set, for example, the coordinates of the vertices and get a static picture of a three-dimensional figure (transparent to see the vertices and faces "from behind")?

Can this be done in HTML/CSS? If not, then maybe there is a library in Java that will generate such a jpeg?

Thanks
