3DimViewer is a lightweight 3D viewer of medical DICOM datasets that is distributed as open source software. The viewer is multiplatform software written in C++ that runs on Windows, Mac OS X and Linux systems. 3DimViewer source codes are available on Bitbucket (https://bitbucket.org/3dimlab/3dimviewer). Video tutorials can be found on YouTube (https://www.youtube.com/playlist?list=PLCvwUmKRw9ZO4YexLKEXmw_2jPo-kXVRn).

LPub3D is an Open Source WYSIWYG editing application for creating LEGO® style digital building instructions. LPub3D is developed and maintained by Trevor SANDY. It uses the LDraw™ parts library, the most comprehensive library of digital Open Source LEGO® bricks available (www.ldraw.org/ ) and reads the LDraw LDR and MPD model file formats. LPub3D is available for free under the GNU Public License v3 and runs on Windows, Linux and macOS Operating Systems. LPub3D is also available as a Linux 'no-install', multi-platform AppImage. Portions of LPub3D are based on LPUB© 2007-2009 Kevin Clague, LeoCAD© 2025 Leonardo Zide, LDView© 2025 Travis Cobbs & Peter Bartfai and additional third party components.

LDView is a 3D viewer for LDraw LEGO models with a focus on quality rendering with good performance. It also contains many features geared specifically toward LDraw part authoring.

GLTF/GLB Windows Shell Extension: This shell extension automatically adds thumbnail images to .glb files in Windows File Explorer and provides a right click menu option to generate a 3D preview image for .gltf files. Supports multi-file select and directory processing. Pre-built Windows x64 installer available at https://buymeacoffee.com/nathancrews/e/255640 LAS/LAZ Pointcloud Windows Shell Extension: This "quick viewer" shell extension provides a Windows File Explorer right click menu option to quickly generate 3D preview images for large and small .las and .laz files. (Disclaimer: Processing time depends on compute hardware) Typical processing time for 100mb .las is about 2 seconds. 25mb .laz file process in about the same times. Files are processed in parallel using available CPU cores. Pre-built Windows x64 installer available at https://buymeacoffee.com/nathancrews/e/255641

GEOMS2 is a geostatistics and geosciences modeling software. Provides interface for grid (mesh), point, surface and data (non-spatial) objects. It has a 3D viewer and 2D plots using the well known Python engines Mayavi and Matplotlib. It has several functions to manipulate your data as well as provide univariate and multivariate analysis. NOTE: The software is still an early beta. Please tell us if you found a bug.

Simple 3D viewer based on QT and VTK

Quantum Mechanical Toolkit And 3D Viewer for C++. Allows Data Visualisation via Images, Surfaces and Volume plots using OpenGL, as well as rapid development Quantum Mechanical Simulations. Uses the Blitz++, VTK Visualisation and Qt Libraries.

Geocando is a 3d viewer for visualisation and querying of geodata and geomodels. It is especially developed for Paradigm's GOCAD(R) objects. Another supported format is the typical GIS exchange format "ESRI Shapefile".

The 3D Toolkit provides algorithms and methods to process 3D point clouds. In includes automatic precise registration (6D simultaneous localization and mapping, 6D SLAM) and other tools, e.g., a fast 3D viewer, plane extraction software, etc.

A Unix-based 3D Viewer for S3d File, used for rendering data collected from common cameras (e.g. stereo cameras)

Create phyiscal simulations easily through IPSA which combines the OpenInventor 3D API with the Open Dynamics Engine (ODE). Scenes are read from .iv files and simulated in the supplied viewer applications. Find it at: http://ipsa.sourceforge.net

I design a basic math theory of 3D and write a linux application to verify my theory. I also upload the document 3DsystemDesign.docx to show the process of my theory.
