Visualization of 4-dimensional regular tilings

Enviado por Jean-François Bigot el Dom, 08/20/2023 - 16:42

This video shows the use of Tak4D to illustrate tilings in a 4 dimensional space. Three regular tilings are made, the first with hypercubes, the second with hexadecachorons and the third with icositetrachorons.

Tak4D is a tool for viewing and manipulating objects in a 4-dimensional space. It allows to apprehend 4D objects through 4 3D views.
These views can be projections or sections.

Waves with icosahedral symmetry on the sphere

Enviado por Nils Berglund el Vie, 08/18/2023 - 11:50

Solution of the wave equation on a sphere. Reflecting obstacles have been placed around the vertices of a regular icosahedron. The initial state is a set of circular waves concentrated at the centers of the faces of the icosahedron.

Solution of the wave equation on a sphere. Reflecting obstacles have been placed around the vertices of a regular dodecahedron. The initial state is a set of circular waves concentrated at the centers of the faces of the dodecahedron.

Ocean Acidification

Enviado por IMAGINARY el Mar, 08/01/2023 - 11:58

CO2 is a chemical that can exist as a gas in the atmosphere but also dissolves into water (as in sparkling water), into rocks, or inside living beings. Oceans store about ⅓ of the CO2 on the planet. This is due to a chemical process known as buffering.

Tipping Point

Enviado por IMAGINARY el Mar, 06/06/2023 - 16:57

In complex systems, a tipping point is where a small change in the system makes big differences in its evolution. Often, these changes are irreversible, or it takes much more effort to reverse than was necessary for the triggering change.

Comic: We need to talk, AI

Enviado por IMAGINARY el Mié, 05/10/2023 - 11:36

Yes, let’s talk. About the foundation of my technology and the opportunities I bring to society. But also about the risks — and how we sometimes misunderstand each other. In which areas is artificial intelligence already helping people? Do you know of any areas in which artificial intelligence is yet to be introduced or should be more prominent? What risks do new technologies pose that worry you?

Virtual Ray Tracer

Virtual Ray Tracer is a Unity application that visualizes ray tracing. The application shows a scene with a camera, lights and objects. Rays slowly shoot from the camera and interact with the lights and objects in the scene. Users can change the settings of the ray tracer and material properties of the objects and see how this affects the rays traced in real-time. The application comes with a number of scenes that introduce the user to settings and controls as well as various ray tracing concepts.
