This repository contains the HTML and Javascript code implementing algorithms discussed in some geometric modeling, geometry processing, and information visualization lectures. This way, the code and some background information about the algorithms can be freely accessed also from outside the University. This website presents the implemented code, which can be cloned from the GitHub site https://github.com/rogrosso/lectures.
The web applications are interactive and based on D3 for 2D graphics and three.js for surfaces. It is strongly recommended to interact with the visualizations by selecting and dragging points, zooming, and rotating the 3D geometry. Some of the applications also include a simple user interface. The code was not implemented for industrial usage or optimized for performance, which makes the implementations much easier to read and understand.
Note: The code was only tested with the Edge and Chrome browsers.
The website is organized into three folders containing the algorithms implemented for three lectures. The folders are the following:
This section implements algorithms for polynomial curves, Bézier- and B-Spline curves. There are also implementations of algorithms for tensor product and subdivision surfaces.
This section contains basic algorithms for geometry processing, such as point cloud registration, surface reconstruction, fairing and remeshing, mesh deformation (ARAP), and parametrization.
This section demonstrates some visualization algorithms for color manipulation, multivariate data, network analysis, visualization, hierarchies, and text visualization.
This project aims to implement all functions and data structures required, up to the libraries for data visualization and HTML processing, such as formulas and code highlighting. Nevertheless, there always will be exemplary implementations of fundamental algorithms that one borrows from the open-source community. Credits will be included in the corresponding file whenever third-party software is used.
