I’m just charging up my old school laptop but here is a similar example of the notes I’m looking for:

Matrix representation of graph node position?

Gents, Having now spent a fair bit of time with Famous vs rolling my own 3d, I’m finding Famous a bit slow to dev with and I think the source of the problem is the coordinate system. Q) Are you considering representing the position of a node using a similar system as famous (position/rotation/scale/etc), or have you considered representing it as a 4x4 transformation matrix instead? While the famous way of doing things is “easier” for the untrained, Matrices are how one is taught these things …

I think the distinction between what has been done in Famous and what I am promoting is that node position shouldn’t be described in terms of a single point but rather as a composition of transformations to a set of points. This is a more robust concept because a node can occupy >> 1 point in the 3d space. Do away with that single point concept and things become much simpler.

The purpose of the core of your framework should then be to introduce the abstract concept of volume in 3-space because this doesn’t exist in the DOM but is required for 3D programming.

Or is changing the way in which coordinates are represented also a purpose of the framework?

This is a highly theoretical question and one worth debating!
