The Generic Mapping Tools and Animations for the Masses
Abstract Generic Mapping Tools (GMT) is a well‐known set of software originally developed for geosciences, allowing scientists in climate and solid earth disciplines to routinely create publish‐ready maps and graphics. However, GMT users rarely make animations despite their undeniable benefit for understanding and teaching dynamic processes. As reading

Transitions between phyllotactic lattice states in curved geometries [PDF]
Phyllotaxis, the regular arrangement of leaves or other lateral organs in plants including pineapples, sunflowers and some cacti, has attracted scientific interest for centuries.

Octree Guided CNN With Spherical Kernels for 3D Point Clouds [PDF]
We propose an octree guided neural network architecture and spherical convolutional kernel for machine learning from arbitrary 3D point clouds. The network architecture capitalizes on the sparse nature of irregular point clouds,and hierarchically ...

Abstract This article gives a detailed description and analysis of Robert Burton's copy of Theatrum urbium italicarum, a Venetian ‘city‐atlas’ produced in 1599 by the engraver and publisher Pietro Bertelli. Burton's copy of the book is especially noteworthy because it has had a number of the maps removed.

THE SPIRALS ON THE OBLATE AND PROLATE SPHEROIDS OF LORENTZ-MINKOWSKI 3− SPACE R13 [PDF]
Spirials are differentiable curves that meet all meridians of a rotational surface at a constant angle. In this study, we obtain differential equations of all spirals on hyperbolic oblate and Lorentzian prolate spheroids.

From the herringbone dome by Sangallo to the Serlio floor of Emy (and beyond) [PDF]
The research starts from an analogy found between two apparently very different structural solutions: the double spiral pattern of the herringbone brick courses in the domes built by Antonio da Sangallo the Younger (1484-1546) during the Renaissance, and

THE LOGARITHMIC SPIRAL AND ITS SPHERICAL COUNTERPART
Logarithmic spirals are isogonal trajectories of pencils of lines. From a series of geometric consequences, we pick out a few which are relevant for kinematics: When a logarithmic spiral rolls on a line, its asymptotic point traces a straight line. Hence,

Tangent Images for Mitigating Spherical Distortion [PDF]
In this work, we propose "tangent images," a spherical image representation that facilitates transferable and scalable 360 degree computer vision. Inspired by techniques in cartography and computer graphics, we render a spherical image to a set of ...
