My solutions to the Advent of Code 2022

libgeom

Geometry library containing the essentials (2d & 3D points/vectors, meshes, B-splines)

dual-contouring

Minimal dual contouring library.

transfinite

A library for evaluating transfinite surfaces.

quadfit

Fit continuously connected B-spline surfaces on sampled points with boundary constraints.

ekcurves

Epsilon-kappa curves

sample-framework

A minimal 3D framework for creating simple applications (intended for class use). Uses Qt / QGLViewer for the GUI and OpenMesh for the mesh data structure.

lispkit

A Scheme implementation of the SECD virtual machine, and a LispKit Lisp compiler.

geo-framework

Basic framework for 3D geometry applications

qds-viewer

Quad patch viewer

bspline-connect

Lightweight library for connecting BSpline patches with G1/G2 continuity

natural-neighbors

fit-sphere

Fitting a sphere with fixed radius on noisy data points.

scanned-dictionary

A webpage that shows a given page of a scanned dictionary.

bezier-triangle

Minimal Bezier-triangle evaluation.

implicitize

Implicitization of polynomial surfaces

persian-poems

Hungarian translation of Persian poems

prolog-leckek

Introductory programming lessons in Prolog (Hungarian)

least

Least polynomial interpolation

minibb

Minimal Bézier/B-spline curve library based on The NURBS Book.

manifold

An n-patch-based construction similar to Zorin's

implicit-curvature

Curvature computation for implicit surfaces

sicp

A CL translation of the examples in the Wizard Book, with solutions to (most of) the exercises

c0coons

Multi-sided C0 Coons patch with rational Bézier boundary curves.

vertebra-fit

Fitting a closed B-spline on a series of points defining vertebrae.

ldni

A CPU implementation of Layered Depth-Normal Images for experimenting.

cl-nurbs

A NURBS library in Common Lisp. It handles both curves and surfaces; it can generate PostScript output for curves and VTK files for surfaces. It also has an own file format (RBN) for storing NURBS data. Features include point / vector operations, curve and surface evaluation, derivation, curvature calculation, algorithms for creating continuity between surfaces and fairing with downhill simplex method, knot removal/reinsertion and fitting.

discrete-clothoids

Test implementation of discrete clothoid curves
