[QGIS-Developer] GSoC QGIS 3D Improvement: Week 11 Report

[Ismail Sunni]

Dear QGIS developers,

Here is my 11th-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 11 Report

*Period*: 5 August 2019 - 11 August 2019

*Report*
1. What did I complete this week?
   - Fixing transparency for the billboard to make it smoother on the edge.
It looks better than the previous result, but still not as smooth as I
expected

   - Adding the layer parameter to the QgsSymbolButton, so that user can
set the symbol using the data from the layer (like common symbol)
   - A lot of debugging why the billboard symbol does not change when the
symbol changed. It does change when I switched the symbol shape (e.g. from
billboard to torus to billboard) or when the altitude clamping is changed
or when the size is changed.
   - Set size from the symbol, still needs some tweak since the billboard
seems too small or too big.
   - Get a fix from Peter regarding the problem with the shader syntax in
macOS
2. What am I going to achieve for next week?
   - Solve using a symbol from QgsSymbolButton
   - Fixing the size issue
3. Is there any blocking issue?
   - Changing symbol doesn't always change the billboard
4. Code
   - Branch for billboard feature [1]
   - Repo for QT C++ billboard [3]
5. Misc
   - N/A
