GSoC 2021 Implement 3D scene visualization support using Potree and integrate with MapMint

Idea
In this project I will be implementing 3D visualization support and integrate it with MapMint. To obtain 3D visualizations, Potree’s GitHub repository will be considered for this task under the JavaScript language. Using Potree I will be integrating the 3D visualizations to MapMint. The dataset for this work being provided through OpenDroneMap, containing files of the type .obj, .las and .ply. These files are of the UAV imagery format and can be loaded on browsers through Potree’s tools and loaders. This will be followed by adding a switcher tab as an addon feature to visualize the OpenLayersMap and 3D visualization. Using this, the user will be able to visualize the 3D scene of a corresponding Georeferenced image.

Project proposal
My proposal for GSoC 2021 got accepted! Link.

Advantages from this project
The implementation of 3D visualization support to Mapmint will be fruitful to the users to obtain 3D visuals of a specific georeferenced data. This enables the users to view any specific scene from the chosen georeferenced data through different perspectives and angles. Example : For instance, consider obtaining a 3D visualization of a multistorey Apartment or a mountain. In order to obtain a descriptive analysis and the visuals of corresponding georeferenced scenes, the user will be able to view the Multistorey Apartment or the Mountain as per their considerations in reference to it’s height and altitude respectively with 3D support.

17th May - 7th June
Community bonding period:
 * 1) Tasks carried out during this period
 * Introduced myself and about my project in the OSGeo SoC mailing List.
 * Created my OSGeo Profile Page and filled in my personal details.
 * Updated my project information on the Wiki Page.
 * Updated the GSoC 2021 Accepted Students Page by adding my User Page, Project Wiki Page and GitHub Repository Links.
 * Had a mentor meeting and interacted with mentors and my partners.
 * Discussed with my mentors about the next steps I should take regarding my project.
 * General discussion regarding any doubts with my partners and mentors on the project Slack channel.

Week 1 - 4 (7th July - 10th July)
Coding Phase 1:


 * Noticed an error that in the r -cran.yml, which is a necessary file needed during MapMint installation. So created a Pull Request for adapting the change in the automated proxy file versions – update_r-cran_version.py
 * Setup MapMint successfully on my machine.
 * Read about different 3D file formats Cesium takes into consideration for visualization
 * Created a documentation for setting up MapMint on OSGeo Live VM.
 * Gone through the Distiller and visualized some 2D GIS data on MapMint.
 * Discussion with my mentors regarding development of project.
