Toward optimizing the design of virtual environments for route learning: empirically assessing the effects of changing levels of realism on memory

open access: yesInternational Journal of Digital Earth, 2019
Broadly, this paper is about designing memorable 3D geovisualizations for spatial knowledge acquisition during (virtual) navigation. Navigation is a fundamentally important task, and even though most people navigate every day, many find it difficult in ...

3D Scene Modeling And Understanding From Image Sequences

open access: yesELCVIA Electronic Letters on Computer Vision and Image Analysis, 2014
A new method for 3D modeling is proposed, which generates a content-based 3D mosaic (CB3M) representation for long video sequences of 3D, dynamic urban scenes captured by a camera on a mobile platform.

Activity Representation Using 3D Shape Models

open access: yesEURASIP Journal on Image and Video Processing, 2008
We present a method for characterizing human activities using 3D deformable shape models. The motion trajectories of points extracted from objects involved in the activity are used to build models for each activity, and these models are used for ...

Thinking out of the box (and back in the plane). Concepts of space and spatial representation in two classic adventure games.

open access: yesEludamos, 2008
In this article we examine location, space and spatial representation in two classic adventure games belonging to the same game series: Gabriel Knight Sins of the Fathers, a one screen at a time point-and-click adventure and Gabriel Knight Blood

A Sparse Voxel Octree-Based Framework for Computing Solar Radiation Using 3D City Models

open access: yesISPRS International Journal of Geo-Information, 2017
An effective three-dimensional (3D) data representation is required to assess the spatial distribution of the photovoltaic potential over urban building roofs and facades using 3D city models.

Uni-Mol: A Universal 3D Molecular Representation Learning Framework [PDF]

open access: yes, 2023
Molecular representation learning (MRL) has gained tremendous attention due to its critical role in learning from limited supervised data for applications like drug design. In most MRL methods, molecules are treated as 1D sequential tokens or 2D topology

A Method of Riemann–Hilbert Problem for Zhang’s Conjecture 1 in a Ferromagnetic 3D Ising Model: Trivialization of Topological Structure

open access: yesMathematics, 2021
A method of the Riemann–Hilbert problem is applied for Zhang’s conjecture 1 proposed in Philo. Mag. 87 (2007) 5309 for a ferromagnetic three-dimensional (3D) Ising model in the zero external field and the solution to the Zhang’s conjecture 1 is ...

A Visual Similarity-Based 3D Search Engine

open access: yesData Science Journal, 2009
Retrieval systems for 3D objects are required because 3D databases used around the web are growing. In this paper, we propose a visual similarity based search engine for 3D objects.
