Re: Game UI is KR: Actionable Knowledge Representation We Already Use Daily

Hi Daniel!

I am very happy to see these threads and K3D in general! You have done an amazing thing catalyzing this project.

> Game UI is already Knowledge Representation

This is the perspective I have been working from for a while.

My goal is to build coherent models for systems meaning I must fit everything into one model. This is an impossible task without a map.

A Visual Canvas that can hold all entities in relation is the only path I see to create such a map.

A system becomes a 3D world of objects one can navigate from all kinds of perspectives.

3D visualization allows for a level of detail needed to represent nuance at scale.

I am working on a visualization engine in TypeScript/JavaScript to proof this approach for a practical application.

I would like to close the gap between what I am doing and K3D so I can leverage K3D approaches.

I would love a new thread on how to implement "K3D compatible components" (or whatever that means) in JavaScript for the purpose of connecting graphs to 2D canvases initially. How do I merge graphs of different concerns to arrive at a complex interactive visualization. What is the backbone of this architecture that I can implement in JS now and scale to everyone's high-entity-count implementations later?

I don't even know where to begin approaching K3D so connecting it to concrete code if possible would provide useful guidance for me and possibly others.

Thanks!
Christoph
