3De Interactive Lenses for Visualization in Virtual Environments
Roberta C. R. Mota, Allan Rocha, Julio Daniel Silva +2
We present 3De lens, a technique for focus+context visualization of multi-geometry data. It fuses two categories of lenses (3D and Decal) to become a versatile lens for seamlessly…
A Comparison of Spatiotemporal Visualizations for 3D Urban Analytics
Roberta Mota, Nivan Ferreira, Julio Daniel Silva +6
Recent technological innovations have led to an increase in the availability of 3D urban data, such as shadow, noise, solar potential, and earthquake simulations. These spatiotempo…
Sub-band coding of hexagonal images
Md Mamunur Rashid, Usman R. Alim
According to the circle-packing theorem, the packing efficiency of a hexagonal lattice is higher than an equivalent square tessellation. Consequently, in several contexts, hexagona…
Automatic Generation of Interpolants for Lattice Samplings: Part II -- Implementation and Code Generation
Joshua Horacsek, Usman Alim
In the prequel to this paper, we presented a systematic framework for processing spline spaces. In this paper, we take the results of that framework and provide a code generation p…
Automatic Generation of Interpolants for Lattice Samplings: Part I -- Theory and Analysis
Joshua Horacsek, Usman Alim
Interpolation is a fundamental technique in scientific computing and is at the heart of many scientific visualization techniques. There is usually a trade-off between the approxima…
Fast and exact evaluation of box splines via the PP-form
Joshua Horacsek, Usman Alim
For the class of non-degenerate box splines, we prove that these box splines are piecewise polynomial. This is not a new result, it is in fact a well known and useful property of b…
