Kokua is an open source metaverse viewer project based on the Second Life Viewer source. Disclaimer: This software is not provided or supported by Linden Lab, the makers of Second Life. The goal of Kokua is to greatly improve the usability of the Viewer through community involvement, thoughtful design, modern development methods, and a pro-change atmosphere.

VGGSfM is an advanced structure-from-motion (SfM) framework jointly developed by Meta AI Research (GenAI) and the University of Oxford’s Visual Geometry Group (VGG). It reconstructs 3D geometry, dense depth, and camera poses directly from unordered or sequential images and videos. The system combines learned feature matching and geometric optimization to generate high-quality camera calibrations, sparse/dense point clouds, and depth maps in standard COLMAP format. Version 2.0 adds support for dynamic scene handling, dense point cloud export, video-based reconstruction (1000+ frames), and integration with Gaussian Splatting pipelines. It leverages tools like PyCOLMAP, poselib, LightGlue, and PyTorch3D for feature matching, pose estimation, and visualization. With minimal configuration, users can process single scenes or full video sequences, apply motion masks to exclude moving objects, and train neural radiance or splatting models directly from reconstructed outputs.

XMIPP is an image processing suite for 3D-reconstruction of biological specimens from transmission electron microscopy data. NOTE that stable releases (including binaries) are longer stored at Sourceforge, but are available at http://xmipp.cnb.csic.es

The littleutils include duplicate file finders (repeats, repeats.pl, repeats.py), image optimizers (opt-jpg, opt-png, opt-gif, recomp-jpg), file rename tools (lowercase, uppercase, pren), archive recompressors (to-gzip, to-bzip2, to-bzip3, to-7zip, to-lzma, to-lzip, to-xz), a tempfile utility (tempname), file property tools (filedate, filemode, filenode, fileown, filesize, and lrealpath), and others. See the README file for more details.

Imprudence is an open source metaverse viewer project based on the Second Life Viewer source. The goal of Imprudence is to greatly improve the usability of the Viewer through community involvement, thoughtful design, modern development methods, and a pro-change atmosphere.

NPDB offers a comprehensive platform for creating and maintaining a database of both old, digitized images and new snapshots captured by smartphones. This versatile system allows users to organize and search through their collection using customizable tags, catering to images of any vintage. One of NPDB's key features is its flexible tagging system, which allows users to categorize their images using an arbitrary set of tags tailored to their preferences. This intuitive approach streamlines the organization process, making it easier than ever to locate specific images amidst a vast collection. Powered by an embedded SQL database, NPDB delivers lightning-fast search results, ensuring that users can access the images they need almost instantaneously. Whether searching by tags or entering free-text queries, NPDB executes SQL queries efficiently, providing accurate results in no time. Developed primarily in C++, NPDB ensures seamless operation on Linux, Windows (via WSL), and Chrome OS.

Aja PHM Studios is a Superwikia codesmith community that builds and maintains 3D portfolios and content for startup semicoms.

This program generates a gallery for your photos, providing several layouts and CSS styles, in order to let you choose a complex page if you don't need to edit it or a basic one if you are planning to use just its code.

Gnome picture Of The Day background changer. Parses the description of the image and saves it to a file so that applications such as conky can read it for display.

Mesh R-CNN is a 3D reconstruction and object understanding framework developed by Facebook Research that extends Mask R-CNN into the 3D domain. Built on top of Detectron2 and PyTorch3D, Mesh R-CNN enables end-to-end 3D mesh prediction directly from single RGB images. The model learns to detect, segment, and reconstruct detailed 3D mesh representations of objects in natural images, bridging the gap between 2D perception and 3D understanding. Unlike voxel-based or point-based approaches, Mesh R-CNN uses a differentiable mesh representation, allowing it to efficiently refine surface geometry while maintaining high spatial detail. The system combines 2D detection from Mask R-CNN with 3D reasoning modules that output full mesh reconstructions aligned with the input image. It has been evaluated on datasets such as Pix3D, where it demonstrates state-of-the-art performance in reconstructing real-world object geometry.

The Open Descent Foundation (ODF) is a community for developers, who want to help to create open source programs, tools, etc. for the famous games Descent1, -2 or -3. Everyone can join the ODF if he accepts the idea of writing open source programs.

Tool kit to use with RenderMan(R) compatible renderers. Include Blender->RIB exporter, shader editor, procedural geometry generators and other useful tools.

The Imprudence and Kokua open source metaverse viewers are developed by Team Purple. This project is for the common stuff that is shared between the two viewers.

"aura" tool is a desktop (X root window) background setter, making heavy accent on image processing and clever scaling (liquid rescale, solid margins cropping, labelling) capabilities.

openSkyMatch is a collection of Linux shell and Python scripts designed for the OpenScience Observatories program. It automates the identification and matching of detected celestial objects in locally captured FITS images with entries in large-scale sky catalogs, notably Pan-STARRS1 DR2 (II/389/ps1_dr2). The toolkit supports data preprocessing, coordinate correlation, and catalog-based validation of astronomical detections. All tools are open-source and optimized for reproducibility and transparency in citizen science astronomy.
