New directions in four-dimensional mathematical visualization
Xiaoqi Yan · 2015
Four-dimension visualization is an interesting topic as we live in a 3D space, we do not have the chance to directly "see," manipulate or "touch" 4D objects. Four-dimensional visualization is an important topic since mathematicians have long been wondering how to visualize beautiful geometries such as knotted spheres, quaternions, and Calabi-Yau space cross-sections, while physicists have been wanting to visualize the hypersphere, which is Einstein's universe.
