LingBot-Map is a specialized project focused on mapping conversational or linguistic interactions within chatbot or AI-driven systems, providing a structured way to visualize and organize dialogue flows. It is designed to help developers understand how conversations evolve across different states, enabling better debugging and optimization of chatbot behavior. The system emphasizes mapping relationships between intents, responses, and transitions, creating a clear representation of conversational logic. It can be particularly useful in complex chatbot systems where multiple branches and conditions need to be managed effectively. The project supports extensibility, allowing developers to adapt the mapping system to different chatbot frameworks or AI models. Its design encourages clarity and transparency in conversational design, reducing ambiguity in dialogue flows. Overall, lingbot-map serves as a tool for improving the structure and reliability of conversational AI systems.

Human Atlas is an open-source interactive 3D anatomy explorer built with React and Three.js. It visualizes the BodyParts3D adult male reference as 2,234 individually selectable anatomical meshes. Users can rotate, zoom, select, isolate, and inspect structures directly in the browser. Fifteen anatomical systems can be toggled independently or viewed through presets such as skeleton and organs. Search covers thousands of named concepts and source identifiers for quickly locating structures. An exploded-view mode separates visible anatomy into a spatial inventory while preserving interactive selection. The interface is responsive for desktop and mobile use and requires no account or API key to run locally.

Importer library to import assets from different common 3D file formats such as Collada, Blend, Obj, X, 3DS, LWO, MD5, MD2, MD3, MDL, MS3D and a lot of other formats. The data is stored in an own in-memory data-format, which can be easily processed. www.open3mod.com/ is a 3D model viewer and exporter based on Assimp that is also Open Source.

This project is no longer valid. See vpython.org.

OpenCTM is a file format, a software library and a tool set for compression of 3D triangle meshes. The geometry is compressed to a fraction of comparable file formats (3DS, STL, COLLADA...), and the format is accessible through a simple, portable API

Intro to CSS 3D transforms is a collection of examples and demonstrations that showcase the capabilities of CSS 3D transforms for creating interactive and visually rich user interfaces. The project provides practical implementations of 3D effects such as rotations, perspective transformations, and animated transitions, helping developers understand how to apply these techniques in real-world applications. It focuses on simplicity and clarity, presenting examples that can be easily adapted or extended. The repository is particularly useful for frontend developers looking to enhance user interfaces with dynamic visual effects. It also demonstrates how to combine multiple transformations to create more complex interactions. The project serves as both a learning resource and a reference for implementing 3D effects in web design. Overall, 3dtransforms highlights the potential of CSS for creating engaging and interactive user experiences.

Tokenize is a Julia package that serves a similar purpose and API as the tokenize module in Python but for Julia. This is to take a string or buffer containing Julia code, perform lexical analysis and return a stream of tokens.

Arbaro is an implementation of the tree generating algorithm described in Jason Weber & Joseph Penn: Creation and Rendering of Realistic Trees

Structure Synth generates 3D structures by specifying a design grammar. Even simple systems may generate surprising and complex structures. Structure Synth offers a graphical environment with multiple tabs, syntax highlighting, and OpenGL preview.
