It is obviously a question of the target of the sample page.
I feel that the examples are meant to demonstrate the great possibilities of three.js.
Therefore, they are often complex and thus hardly manageable for the beginner. Even if you’ve been working with three for a while, you’ll need some time to put the core of the thing into a simple example and remove the stuff that wasn’t needed or considered before.
So you would need two categories of examples:
- demonstration of the individual functionalities,
- complex examples.
But this makes a lot of work and could surely only be considered as a long-term goal.
By the way, the problem is a major reason why I started the Collection of examples from discourse.threejs.org.
Recently, more and more questions and examples are posted with use of more external libraries and especially react.
This does not make it easier for the “normal” three.js user.
(One example: Mapping Text onto faces of Cube - #14 by drcmda … )
There was already a discussion here to mark these questions separately to “questions”.
I decided not to include such examples (as a rule) in my collection.
