WebGL Framework

Hello everybody,

I need information about WebGL frameworks.
I would like create an application which can load a .stl file and use it.
My .stl file contains a bone, it’s for a medical application. I will display the bone in 3D and cut it with spécifies parameters.
I know that it exists a lot of framework like three.js etc… but what framework could I use for it ? What the most adapted in my case?
