Should the Elements of Diagrams Be Rendered in 3D?

چکیده
To some extent the utility of a diagram depends on how effectively the information can be perceived. We have applied the structural object recognition theory of Biederman to the problem of constructing node-link diagrams. According to geon theory, as objects are perceived they are decomposed into 3D primitives called geons, together with the skeleton structure connecting them. This work evaluates diagrams using geon-like primitives. Results of two experiments are reported. These show that diagrams constructed of 3D components can be visually analyzed more rapidly, with fewer errors, and can be remembered better in comparison with equivalent 2D silhouette diagrams.

Investigating Translation Strategies of Culture-Specific Items in Alignment with Nord’s Binary Translation Typology: A Case Study of Unaccustomed Earth
Culture is an extremely complex concept. Translating cultural elements is a demanding task due to the fact that these elements comprise specific meanings and implications belonging exclusively to the lan-guage and culture from which they have emerged. Regarding this point, the present article investigated the strategies employed for translating culture-specific items (CSIs) in an English nov...
متن کاملTarget detection Bridge Modelling using Point Cloud Segmentation Obtained from Photogrameric UAV
In recent years, great efforts have been made to generate 3D models of urban structures in photogrammetry and remote sensing. 3D reconstruction of the bridge, as one of the most important urban structures in transportation systems, has been neglected because of its geometric and structural complexity. Due to the UAV technology development in spatial data acquisition, in this study, the point cl...

Granitoid bodis of Kuhmish are located about 30 km south of Sabzevar city. In terms of tectonic classification, Kuhmish granite was considered to be part of Sabzevar zone. Conglomerate, tuff, sandstones of Paleogene age and tuff units, radiolarites, andesite and diorite with UpperCretaceous age form the main litological units of the study area. Granitoid bodies involves aacidic part with combin...

Moshirabad granitoid body is located, as part of intrusive bodies, in Sanandaj-Sirjans zone and crops out elongated with east-west trend. Based on field observation as well as mineralogical characteristics, this suite consists of three main units; diorites, granodiorites and granites, followed by minor gabbros. Mineralogical and geochemical studies show that rocks of this suite are I-type, calc...
متن کاملA Macro-model for Nonlinear Analysis of 3D Reinforced Concrete Shear Walls
Architectural limitations in many situations make it necessary for the RC shear walls to be extended in plan in different directions at a single location that makes them a 3D configuration. Analysis of such walls is very challenging. In this research about 450 cases of 3D shear walls are considered with different shapes and heights. L, T and H-shape walls are studied. They are nonlinearly analy...
