How to programmatically render a 3D model?

Question

Java

You need to programmatically render a 3D model (mostly stl format) to png. In this case, it is necessary to additionally calculate its volume, the number of polygons and other parameters.
Can you tell me which libraries can be used to do this (in java or php)?

Answer 1

Look towards java engines like jmonkey or more primitive wrappers for opengl like https://ru.wikipedia.org/wiki/Java_OpenGL
