For billboards that do not rectangular shape (a circle) yes that should be
possible and easy to support fully transparent pixels. For semi-transparent
images, there will be an issue, rendering output is not going to look good
without some special techniques because of how Z buffer works and because
objects would need to be always rendered back to front (from camera's view)
for alpha blending to be correct.

I imagined more they would behave like real billboards, facing a particular
direction (or at least having the option to do that).

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/

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

Thanks! Do the billboards always face the camera? Or can you fly behind them? 
And will you give them a little pin and frame to anchor them to a place?

Hi Tim,

Hehe, yeah, I am the one who missed it. I put it in my billboard repository
now: https://github.com/ismailsunni/qt3d-custom-shader/blob/master/README.md
(both
screenshot and screencast). I will update my weekly report to show the
screenshot and the screencast.

You can also see it here:

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

[Ismail Sunni]

Dear QGIS developers,

Here is my 7th-week report for my GSoC Project[7]. You can also check the
project wiki page [3]. Comments and suggestions are welcome :)

GSoC QGIS 3D Improvement Week 7 Report

*Period*: 8 July 2019 - 14 July 2019

*Report*
1. What did I complete this week?
   - Porting billboard from QML to QT C++ [4] as my discussion with mentors
to start from outside QGIS first.
   - Learning GLSL
   - Add UI for the billboard options (very initial work only) [1]
2. What am I going to achieve for next week?
   - Move the ported billboard to QGIS code
   - Work on the applying billboard workflow
3. Is there any blocking issue?
   - Debugging in 3D stuff is not easy. Especially when something is not
shown up and no error message. I got an obstacle when the billboard didn't
show up. But finally Martin helps me, and it's fixed.
4. Code
