[QGIS-Developer] GSoC QGIS 3D Improvement: Week 7 Report

[Ismail Sunni]

Hi Tim and Mathieu,

Thanks! Do the billboards always face the camera? Or can you fly behind
> them?


It will always face the came, by definition :).

And will you give them a little pin and frame to anchor them to a place?


Do you mean like a line to connect the billboard to the terrain? There is a
wishlist for that. But the first step, render this billboard on QGIS first.

 Nice screencast. Are billboards able to handle alpha/opacity channel for a
> given raster?


Do you mean the billboard is transparent and we can see the stuff behind
it?

Well, I am not in that level of understanding of this 3D rendering. But I
can say it's not easy to do something transparent in the 3D world. Since we
need to reconsider how it will be done (without transparency means we just
ignore the covered surface of the 3D objects, while with transparency we
need to know the order of the object). That's what I got from my discussion
with Martin. *Please correct me if I am wrong Martin :)

Best regards/
