If one day 3D humans had to pass a examination to obtain residency in the 4D World, would you be able to succeed? I created an online exam. Some questions are easy, while others are quite challenging.

The vessel Endeavour strays into a hyperbolic universe of extreme curvature and crash-lands on an infinite planet. An adventure into the geometry and an encounter with an alien civilization begin...

This time, we'll explore the laws of the 4D universe - General Relativity in 5D spacetime (4 spatial + 1 time dimension) and the structure of rotating black holes.

This article continues delves into rendering, rotation control, and advanced materials through a dynamic material and lighting scene, and a dice control example.

Today we begin a new series introducing how to use the 4D graphics engine Tesserxel to write your own 4D scenes. This is aimed at readers who already have some coding background, have worked with Java

This article introduces the representation of lines and cells in the state space to solve plane-cell and line-plane angle range problems. This article also introduces how 4D rotations correspond to tr

This article defined an abstract plana state space for easier geometric visualization of angles between planes, extending angles from acute to real number. A simulator explores their possible ranges.

Let's look at possible fictional 4D molecules. KWOK Chun shared a similar 4D periodic table with me. 4denthusiast built a framework of particle physics and pioneered 4D computational chemistry.
