What alternatives for openCascade are free and smaller

Hello everyone In principle, I like to experiment with a 3D modeling building, which could also raytrace the final result, I found only openCascade lib for such work. My question is, is this the only alternative for such a task? (they need to look for a library and not have to deal with low openGL)

I have been using Opencascade for a while, and I am very impressed with its modeling capabilities. Its performance is well suited for objects with simple and medium complexity, but some operations (especially 3d-Boolean for objects of medium complexity) take a lot of time.
