Visualizing Squircular Implicit Surfaces
Chamberlain Fong
The squircle is an intermediate shape between the square and the circle. In this paper, we examine and discuss equations for different types of squircles. We then build upon these…
Elliptification of Rectangular Imagery
Chamberlain Fong
We present and discuss different algorithms for converting rectangular imagery into elliptical regions. We mainly focus on methods that use mathematical mappings with explicit and…
Squircular Calculations
Chamberlain Fong
The Fernandez-Guasti squircle is a plane algebraic curve that is an intermediate shape between the circle and the square. It has qualitative features that are similar to the more f…
Analytical Methods for Squaring the Disc
Chamberlain Fong
We present and discuss several old and new methods for mapping a circular disc to a square. In particular, we present analytical expressions for mapping each point (u,v) inside the…
Revolvable Indoor Panoramas Using a Rectified Azimuthal Projection
Chamberlain Fong
We present an algorithm for converting an indoor spherical panorama into a photograph with a simulated overhead view. The resulting image will have an extremely wide field of view…
Warping Peirce Quincuncial Panoramas
Chamberlain Fong, Brian K. Vogel
The Peirce quincuncial projection is a mapping of the surface of a sphere to the interior of a square. It is a conformal map except for four points on the equator. These points of…
Methods for Accelerating Conway's Doomsday Algorithm (part 2)
Chamberlain Fong, Michael K. Walters
We propose a modification of a key component in the Doomsday Algorithm for calculating the day of the week of any calendar date. In particular, we propose to replace the calculatio…
