Re: [QGIS-Developer] GSoC project scope discussion
Hi BELGACEM, 1) Is there a written list of features that QGIS 3D has ? I don't see the > 3D map view fully integrated within QGIS especially for scripting. This Martin's presentation in FOSS4G perhaps can show the current list of features also: https://www.youtube.com/watch?v=stKWTOI0dFc=4s Best regards On Wed, Mar 11, 2020 at 3:43 AM BELGACEM NEDJIMA wrote: > Hello Martin, > Thank you for your positive reply! > I just updated the GitHub repository with some screenshots of the things > I made with my graphics engine.

Re: [QGIS-Developer] GSoC project scope discussion
Hello Martin, Thank you for your positive reply! I just updated the GitHub repository with some screenshots of the things I made with my graphics engine. I started learning opengl January last year and didn't think I will have good results to share (I was just playing around) and when I heard about google summer of code I figured it will be a good chance to prove that I know how to code in C++ (despite some bad practices I did there like the obvious awful cmake file that I only noticed when I was writing the readme file ). sorry for not writing a proper readme from the start, I will be glad to hear your opinion about my hobby project. Link to the readme file: https://github.com/NEDJIMAbelgacem /Graphics_Engine/blob/master/README.md I will be happy to discuss with you the list of features requested for QGIS, I can start developing the features and familiarizing eith the codebase before GSoC starts (even if I don't get accepted I think I can learn a lot from QGIS code base).

Hi Nedjima Welcome to the qgis-dev mailing list! Please see my comments below.

That sounds great! I have seen on your github profile that you have developed a graphics engine: https://github.com/NEDJIMAbelgacem/Graphics_Engine Could you tell us a bit more about it? Maybe add some screenshots with 3D eye candy? :-) > I would like to ask some questions and document myself about the capabilities > of QGIS 3D. > 1) Is there a written list of features that QGIS 3D has ?

There is some user documentation here: https://docs.qgis.org/testing/en/docs/user_manual/introduction/qgis_gui.html#d-map-view But it is not really a complete list of features... Regarding python scripting, there is limited integration: you can configure 3D symbols for vector layers and mesh layers, but currently you cannot interact with a live 3D scene in Python. This is mainly because that would require addition of PyQt3D as a dependency of QGIS (the "ordinary" PyQt5 does not contain python wrappers for Qt 3D framework). https://www.riverbankcomputing.com/software/pyqt3d/intro So far I did not need that so I skipped the integration for now, but it would be definitely useful to have. > 2) From the proposed project ideas list I saw in the QGIS wiki I feel like we > need to implement a graphics engine for the 3D map view that takes MDAL data. > I would like to know more about the already existing structure of rendering > and whether OpenGL is used currently or not. I read through the docs but it > looks a little confusing to me (lots of classes). The proposed project ideas are mostly independent from MDAL data. For example with vector layer data we tessellate them (if needed) to create meshes and display them in 3D views. By the way, MDAL data already can be displayed in the 3D views (in QGIS 3.12) and there are more improvements coming, e.g. https://github.com/qgis/QGIS/pull/34945 All 3D rendering is done with Qt 3D and yes, it is based on OpenGL. We use some basic shaders from Qt 3D Extras library (e.g. material for Phong lighting), but there are several custom shaders we use (e.g. rendering of lines, instanced rendering of points, rendering of points as billboards, mesh layer rendering). I would be happy to discuss with you the list of ideas and what I think would be the necessary tasks to complete them. I am also open to any own ideas about things that could be improved in QGIS 3D. > 3) I find the navigation of the 3D map view quite hard to use properly (I > understand that's a problematic thing because I already had troubles with > that while making my own OpenGL graphics renderer). Do other people also find > that a problem ? I may try getting into that if you want. I have seen people "fight" with the navigation too... There are surely some ways how to improve this - but first of all we should make a list of problems with the navigation and see how we could fix them. If you would have some free time, it would be good to set up a teleconference to discuss things in a bit more detail.

[QGIS-Developer] GSoC project scope discussion
Hello QGIS developers, I am Nedjima Belgacem, a fourth year computer science student at ESI-Algiers (Ecole supérieure d'informatique), Algeria. I am willing to contribute to QGIS project by working on QGIS 3D features as a part of GSoC program and beyond. I am proficient in C++ and python, I have experience working with Qt and OpenGL. I would like to ask some questions and document myself about the capabilities of QGIS 3D. 1) Is there a written list of features that QGIS 3D has ? I don't see the 3D map view fully integrated within QGIS especially for scripting. 2) From the proposed project ideas list I saw in the QGIS wiki I feel like we need to implement a graphics engine for the 3D map view that takes MDAL data. I would like to know more about the already existing structure of rendering and whether OpenGL is used currently or not. I read through the docs but it looks a little confusing to me (lots of classes). 3) I find the navigation of the 3D map view quite hard to use properly (I understand that's a problematic thing because I already had troubles with that while making my own OpenGL graphics renderer). Do other people also find that a problem ? I may try getting into that if you want. Have a nice day :) Best regards. ___ QGIS-Developer mailing list QGIS-Developer@lists.osgeo.org List info: https://lists.osgeo.org/mailman/listinfo/qgis-developer Unsubscribe: https://lists.osgeo.org/mailman/listinfo/qgis-developer
