Currently I'm developing a high-performance 3D editor shown by the following screen-shot. When I say high-performance, I mean that the 3D editor should be capable of handling STL files, several GB in size.
I'm using OpenGL for development. The problems with OpenGL is being low-level and consequently slowing down the development.
I'm afraid there might be any high-performance commercial or free/open-source library/API which I'm not aware of. Is there any high-performance library/API which can speed up the development of a 3D editor like mine? So far, I've found Qt3D module. Thanks.
I found a list here.
