VGGSfM
VGGSfM: Visual Geometry Grounded Deep Structure From Motion
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. ... -

A Book Of CEFT
Co‑Emergent Field Theory presents a unified generative framework.
Co‑Emergent Field Theory (CEFT) presents a unified generative framework for understanding how structure, identity, memory, meaning, and cognition arise from a single closed dynamical loop. Beginning with the minimal triad of displacement, responsiveness, and coherence, CEFT shows how a dynamic Φ‑field self‑organises into wells, corridors, attractors, and ultimately the VRP — the singular point from which perspective, agency, and identity emerge. From this foundation, CEFT develops a complete account of memory wells, associative corridors, learning dynamics, attention, interpretation, and semantic manifolds — revealing cognition not as computation, but as geometry: a self‑stabilising, self‑interpreting field of meaning. ... -

G3N
Go 3D Game Engine
G3N (pronounced "gen") is an OpenGL 3D Game Engine written in Go. It can be used to write cross-platform Go applications that show rich and dynamic 3D representations - not just games. A basic integrated GUI framework is provided, and 3D spatial audio is supported through OpenAL. Go 1.8+ is required. The engine also requires the system to have an OpenGL driver and a GCC-compatible C compiler. On Unix-based systems, the engine depends on some C libraries that can be installed using the... -

Nerfies
This is the code for Deformable Neural Radiance Fields
Nerfies demonstrates deformation-aware neural radiance fields that reconstruct and render dynamic, real-world scenes from casual video. Instead of assuming a static world, the method learns a canonical space plus a deformation field that maps changing poses or expressions back to that space during training. This lets the system generate photorealistic novel views of nonrigid subjects—faces, bodies, cloth—while preserving fine detail and consistent lighting. -

OghamStars
Draw stars dynamically & adjust draw parameters in real time. Fun!
Starting with an N-gon of N sides we create an X gon with all possible interconnections, drawn not all at once but line-by-line. Transparency, color, and line thickness, draw speed, can all be adjusted. Symmetry can be maintained or broken. Algebra is given in the program that describes the number of points formed in the geometry, the number of overlapping triangles, the number of possible angles, and the number of lines, all equations based on the parameter 'X'. This program is... -
