In general three.js is immensely useful and well designed. There is one design decision that makes no sense to me: Geometry does not derive from Object3D. Why? Some context: I often have the need to manipulate geometry before I insert it into a mesh. But all the properties I would expect to be part…

In a scene graph library you usually have a class for modelling the 3D hierarchy. Sometimes it’s called Node, Entity, Component or Object3D in the case of three.js. Such 3D objects have a position, rotation and scale component and also derive their transformation to their descendants. Materials and…

I get that. It just makes it awkward If I simply want to position and orient a box or cylinder independent of it its parent mesh.

For context see my question - which I solved here: [image] How do I align a cylinder along an axis? Questions I am trying to position and orient a set of cylinders. As input I have a list of xyz locations. Each cylinder is positioned and oriented from successive pairs of x…
