[QGIS-Developer] GSoC 2019 for QGIS 3D Improvement Proposal

[Ismail Sunni]

HI Mathieu

Regarding on-screen navigation, it'd be good to think of an implementation

Hmm, yeah, I will think about it in the design. I agree, if it can be used
on other part, it will be better for sure.

 Hi Nyall,

Great proposal Ismail -- all these features would be lovely to see!

As Martin said, it's a good point. I will be happy to re-use existing code,
I think it's a win-win solution.

Thanks, Nyall

Yeah, regarding the billboard, that's one of the common use cases that
Martin and I discussed. So it's under my radar to have something like that
in the implementation. Btw, thanks for your comments in the Google Doc.

Those two ideas are interesting and should be implemented somehow in the
future. But as you said, perhaps it's too much for the GSoC proposal :). I
can't promise, but who knows what will happen in the future :)

I can only add that I am also happy that Ismail would like to

Thanks for your help and guidance, Martin :)

Best regards
