I'm an open source advocate and been asked to present to a top management in government regarding the availability of open source 3D tools and software that leads to SmartCity/SmartNation initiatives.
It is very difficult to keep track of what's happening around the world in 3D GIS space. Hope you can enlighten. Looking for open source initiatives, as a priority.
I have broken down into categories, if you have anything new other this list, that's what I'm interested.
3D GIS is tightly related to Point Clouds so let's start from there
LiDAR/Point Cloud
- LASTools - LiDAR processing
- PgPointCloud - PostgreSQL extension for storing Point Clouds
- PDAL - Point Cloud Data Abstraction Library like GDAL
CityGML
- 3D City Database The CityGML 3D City DB
JS Libraries
- CesiumJS JavaScript library for world-class 3D globes and maps
- Cesium 3D Tiles 3D tiles spec for CesiumJS
- ThreeJS 3D javascript library. QGIS has a plugin.
Projects
Non-GIS, but of interest
- Unity 3D engine The most popular 3D gaming engine
- Blender Open source 3D model creation
Obsolete
- Glob3 open source 3D GIS multiplatform framework written in java
I know GRASS GIS has 3D capabilities.
Can you let me know what else is out there?
