[HTML][HTML] Uniform spherical grids via equal area projection from the cube to the sphere

D Roşca, G Plonka - Journal of Computational and Applied Mathematics, 2011 - Elsevier
We construct an area preserving map from a cube to the unit sphere S2, both centered at the
origin. More precisely, each face Fi of the cube is first projected to a curved square Si of the …

An area preserving projection from the regular octahedron to the sphere

D Roşca, G Plonka - Results in Mathematics, 2012 - Springer
In this paper, we propose an area preserving bijective map from the regular octahedron to
the unit sphere S^ 2, both centered at the origin. The construction scheme consists of two …

Wavelets on manifolds

ST Ali, JP Antoine, JP Gazeau, ST Ali… - … States, Wavelets, and …, 2014 - Springer
In this chapter, we discuss the construction of wavelets related to other groups than
similitude groups. The first, and most important, case is that of wavelets on the two-sphere …

A Square Equal-Area Map Projection with Low Angular Distortion, Minimal Cusps, and Closed-Form Solutions

MA Petroff - ACM Transactions on Spatial Algorithms and Systems …, 2021 - dl.acm.org
A novel square equal-area map projection is proposed. The projection combines closed-
form forward and inverse solutions with relatively low angular distortion and minimal cusps …

[PDF][PDF] Area preserving maps from rectangles to el-liptic domains

D Rosca - STUDIA UNIVERSITATIS BABES-BOLYAI …, 2011 - users.utcluj.ro
We construct a bijection from R2 to R2, which maps, for each α∈(0,∞), rectangles of
arbitrary edges 2αL1, 2αL2 onto ellipses with semi-axes αa, αb, with a, b satisfying 4L1L2 …
