Again, a similar motion can be seen with squares in a 3D cube projection. Rotate on one plane and you see the cubes growing and shrinking as they move in and out of the center. This is all analogous to the 2 squares connected by trapezoids you see in the projection of a 3D cube. The outer cube appears larger because it's near us on the w axis, and the inner cube appears smaller because it's further away.Īll 6 connecting cubes are moving from near to far so they get skewed into trapezoidal prisms along the way. To see how this affects the tesseract’s 8 cubes, set all the rotation sliders to 0°. Remember that due to projection, points that are further away on the w axis will shrink towards the center of the 3D image. 1140–1164.To start, just play around with all the rotation sliders to see how the projection morphs around.

Furthermore, we show an application to a synthetic construction of a spherical inversion and visualizations of double orthogonal projections and stereographic images of Hopf tori on a 3-sphere generated from Clelia curves on a 2-sphere. Consequently, the double-orthogonal projection of a freehand curve on a 3-sphere is created inversely from its stereographic image. Described are synthetic constructions of stereographic images of a point, hyperspherical tetrahedron, and 2-sphere on a 3-sphere from their double orthogonal projections. We present an interactive animation of the stereographic projection of a hyperspherical hexahedron on a 3-sphere embedded in the 4-space. The double orthogonal projection of the 4-space onto two mutually perpendicular 3-spaces is a method of visualization of four-dimensional objects in a three-dimensional space.
