### What is the representation of the triangle group for the uniform (4 4 4) tiling of hyperbolic disk in terms of Mobius transformations?

I wonder how can one descibe the generators of the triangle group for the tesselation of Poincare unit disk by triangles with angles $\pi/4, \pi/4 , \pi/4$ in terms of the action of the modular ...

### Is there any way to produce a random Voronoi diagram with a specific length and width? [closed]

A Voronoi diagram is an approach to the tessellation of medium. In this diagram, there are many points in a plane that divide the medium to many specific regions by their bisector. Any region is ...

### What regular or semiregular hyperbolic tiling has the smallest average tile area?

I have noticed that hyperbolic tilings tend to be rather "sparse" in that each tile takes up a lot of space. If I remember correctly, for a given curvature the area of any tile in a given hyperbolic ...

### Can the 2D plane be tessellated with a finite set of closed curves that have Geometric continuity > 1?

When I think of tessellating the 2D plane, all examples I can think of (squares, hexagons, rhombuses, polygonal stars...) have at least one point that is G1 continuous, even these fish: Is it ...

### Properties of Thiessen Polygons

Given a convex polygon, how does one test whether it's part of a Voronoi tesselation? In other words, what is a quick way to test if a polygon is a Thiessen polygon? I suspect one test could involve ...

### Triangle interpolation with 6 control points?

Through a costly simulation, I am able to calculate the value of a function at several discrete points on a plane. My task now is to interpolate, to find the values at all points of the grid. (It is a ...

### How heptagon tesselation layout is computed in hyperboloid model?

I want to try using heptagon-hexagon tesselation grid in hyperbolic plane like the one used in HyperRogue. This is how I understand it: First, graph representing tesselation is generated. (done) ...

### Is it possible to tile two planes, which have some line segments identified, in ways which can't be replicated on just one?

Suppose you have two Euclidean planes, and there is some set of pairs of points (themselves pairs of coordinates) such that for each such pair ((ax,ay),(bx,by)), the line segment connecting the point (...

### Higher dimensional plane tessellation

Let $n$ be some finite positive integer value. Now consider the plane $z=n-x-y$, so the points $(n, 0, 0), (0, n, 0), (0, 0, n)$ bound the region of the plane with strictly non-negative coordinates. ...

### Do the loops “Snakes” by M.C. Escher correspond to a regular tilling of the hyperbolic plane?

In M.C. Escher's Snakes, you have three snakes going through some loops. I'm more interested in the loops though. In this image, a ring model of the hyperbolic plane is given. It is given by \$w=e^{za}...
