Multiview matching with deep-learning and hand-crafted local features for COLMAP and other SfM software. Supports high-resolution formats and images with rotations. Both CLI and GUI are supported.

Julia implementations for different rotation parameterizations

Numeric and symbolic quaternions package for Mathematica. Focus is on coordinate frame orientations. Converts between quaternion, matrix, angle/axis and EulerZYX.

Source code for the paper "On nonlinear geometric transformations of finite elements" implementing various geometrically exact finite element formulations for the special Cosserat rod.

Quaternion algebra in 3D - including plot functionality

A Python-based Rubik's Cube simulator and visualizer using matrix algebra for efficient representation, manipulation, and visualization of the cube's state. Includes a group theory approach to cube operations and a proof-of-concept visualization module using Matplotlib.

Implementations of CV concepts related mostly to Single or Two view geometry

ImGui GIZMO widget - quaternions based 3D object manipulator: it permits, via mouse, to manipulate objects by translating, rotating, or scaling them

AVL-AlgoX is an implementation of an AVL tree, a self-balancing binary search tree where the difference between heights of left and right subtrees cannot be more than one for all nodes. This program allows insertion, deletion, and searching of nodes while ensuring the tree remains balanced through rotations.
