Hello,
As often in OpenSource projects and engineering teams, I have the
impression that we are looking for solutions before having defined the
problem.
3D engines are as diverse as use cases can be. Without a clear vision of
what we would like for 3D in QGIS in terms of features and goals, I do
not see the point in assessing technical solutions.
You cannot compare 3D framework if you do not know if your main goal is
photorealistic rendering of objects, or 3D analysis ( or both ).
I would rather suggest to :
- ask end-users (and not developers) about what they really need in 3D
- gather real-world use cases from users
- get a list of features for 3D in other softwares ( ESRI & others )
- start establishing a roadmap and vision from these elements
- THEN and only then, look for technical solutions
Hi,
I've been working under the assumption that our goal would be to
replicate QGIS' existing 3D functionality, just with a new engine.
It would certainly be nice to have a formulated long-term plan for the
3D view, but I think that's somewhat orthogonal to the engine change.
I'm not even sure how such a thing based primarily on user input would
be created or applied when most work is funded by contracts for
particular tasks.
