🌸 DETAILED DESCRIPTION 🌸

so like, fields are the data containers in the scene graph. nodes and engines all use fields to store their public data. that's the whole job, and they do it flawlessly, no cap 🫶

fields can be inter-connected, which means a change at one location in a scene graph makes other parts of the scene graph automatically get updated too. the way that works: direct field-to-field connections cause values to get duplicated, while field connections together with engines can create whole complex networks for that updating, including mathematical computations and logical operations. and listen — field connections are uni-directional, but if you set up a connection in both directions you get yourself a bi-directional connection. it's giving mutuals 🤝

fields split into two groups first: "single fields" and "multifields". single-fields contain just one value, while multi-fields can contain many values — or even none at all. iconic range, honestly 💅

besides the fields that are part of nodes, you also have "global fields". the "realtime" field is one such field.

and the fields in VRML97 nodes have additional semantics, bestie, pay attention: some are "event_in" and some are "event_out", listening for events or triggering events.

⚠️ "event_in" events should not be read from, and "event_out" fields should not be written to. like, do not do it. that's the rule, fr fr 🙈
