Bubble Clouds: 3D Display Composed of Soap Bubble Cluster
We examine Bubble Clouds composed of a bubble cluster for a three-dimensional display. A bubble cluster is flexible in that its shape can be modified and it can float in the air with helium gas confinement of the bubbles. By varying the density of the bubble clusters, we project images onto the bubbles without requiring fog confinement or use of special equipment. Moreover, we investigate wheth...
متن کاملPlanar soap bubble clusters with multiple cavities
The floppiness of bubble chains and the rigidity with respect to slidings of three-bubble clusters are used to construct numerically degenerate local energy-minimizing bubble clusters in the plane with as many cavities as desired. Experimental demonstrations are also given. © 2009 Elsevier Ltd. All rights reserved. 1. Formulation of the problem and experimental demonstration The purpose of this...
متن کاملThe Planar Soap Bubble Problem with Six Equal Pressure Regions
The planar soap bubble problem is the mathematically analogous problem in two dimensions to search for the least-perimeter way to enclose and separate regions R1, . . . , Rm of given areas A1, . . . , Am on the plane. In this work, we study the possible configurations for perimeter minimizing enclosures for more than three regions. In particular, we focus on the case of equal pressure regions. ...
متن کاملAnimation of Soap Bubble Dynamics, Cluster Formation and Collision
The deformable models are useful for variety of computer graphics applications. Because they are dynamic, our models are well suited to physics-based animation tasks. This paper deals with a complete computer simulation of soap bubbles from a dynamic perspective, which should prove to be of great interest to physicists and mathematicians. We discuss the dynamic formation of irregular bubble clu...
متن کاملSoap bubble appearance in brain magnetic resonance imaging: cryptococcal meningoencephalitis.
Although cryptococcal infections begin in the lungs, meningoencephalitis is the most frequently encountered manifestation of cryptococcosis among individuals with advanced immunosuppression. As the infection progresses along the Virchow-Robin spaces, these structures may become dilated with mucoid material produced by the capsule of the organism. We report a case of a 24-year-old man with crypt...
