Hi Tim,

Thanks Sunni! I had a long chat with Martin this week and he basically told

Ahaha, yes, it's different. I thought the same thing when I heard it for
the first time :D

 So now I am convinced but still not sure what will actually be put in the

Well, if you want to configure it from the data, it should be possible (or
I should make it possible) to do it from the symbol. Since we can use an
expression to configure the symbol, it's mean we can also configure the
billboard also.

Hopefully, I can show how to do it in this week.

Best regards.

Hi

Thanks Sunni! I had a long chat with Martin this week and he basically told me: 
“Tim you are an idiot, 3D Billboards are not the same as real life billboards, 
they should always face the camera” :-)

So now I am convinced but still not sure what will actually be put in the 
billboard i.e. how will I configure its contents based on some data from my 
layer?

Thanks!

Regards

Tim

Hi Tim,

Thanks for the feedback and sorry for the late reply.

Thanks for the update! Maybe I missed it, but what is planned to eventually

The common usage is to put a label or sign of a place. Something like this
in Google map. In this case, the sign is better to have the same size and
always facing the same direction. When we zoom out, we can see where is the
place since the billboard will still have the same size. And when we rotate
or tilt the map, we can still see it properly also.

https://user-images.githubusercontent.com/1421861/62011693-eb66fe00-b17b-11e9-939d-d5cbb1955899.jpg

In my last week report, it's getting better, like the screenshot below.

https://user-images.githubusercontent.com/1421861/62011245-19e1da80-b176-11e9-8da4-df6f9bd6d004.jpg

Regarding a tooltip or a label text, I haven't thought about it. I am not
sure it's possible to do it even for a normal symbol. Using the identify
tool is one of the option to know what is it in the billboard.

Another good example of a billboard is this
https://cesiumjs.org/Cesium/Build/Apps/Sandcastle/index.html?src=Billboards.html

I hope my explanation is quite clear.

Best Regards.

Hi Sunni

Thanks for the update! Maybe I missed it, but what is planned to eventually go 
in the billboard? The kid pic is nice for a proof of concept but have you made 
a concept render of the how the final thing will look? It would be nice for the 
billboard to use the tooltip text or the label text - it that the plan? I’m 
still not convinced it wouldn’t be better having the billboard facing a fixed 
(or used defined fixed) direction but maybe I am alone in this….when I watch 
the youtube clip the boards seem to go ‘flat on the ground’ and lose their 3d 
representation. 

Regards

Tim

[QGIS-Developer] GSoC QGIS 3D Improvement: Week 8 Report

[Ismail Sunni]

Dear QGIS developers,

Here is my 8th-week report for my GSoC Project[4]. You can also check the
project wiki page [2]. Comments and suggestions are welcome :)


GSoC QGIS 3D Improvement Week 8 Report

*Period*: 15 July 2019 - 21 July 2019

*Report*
1. What did I complete this week?
   - Porting Billboard functionality from my experimental repo[3] to QGIS
codebase[1]. Success with a static image, and currently polishing with
default symbol (still looks ugly symbol).
   Sample result can be watched below (click and it will play on YouTube):
- QGIS 3D Billboard Rendering with Succes Kid (static) (
http://www.youtube.com/watch?v=Dxsu0ZaDd0k)
- QGIS 3D Billboard Rendering with Default QgsSymbol - still ugly (
http://www.youtube.com/watch?v=32Tv7y07vXg)
2. What am I going to achieve for next week?
   - Make the billboard shows symbol from user
   - Polishing
   - Fill 2nd evaluation
3. Is there any blocking issue?
   - It seems, adding an image (not from a file) to the texture is not
straight forward.
4. Code
   - Branch for billboard feature [1]
   - Repo for QT C++ billboard [3]
5. Misc
   - N/A
