Stream Processors Texture Generation Model for 3D Virtual Worlds: Learning Tools in vAcademia

Abstract

In this paper, we address the challenges of applying three-dimensional virtual worlds for learning. Despite the numerous positive conclusions, this technology is far from becoming mainstream in education. The most common problems with applying it in everyday teaching and learning are steep learning curve and demand for computational and network resources. In order to address these problems, we developed a stream processors texture generation model for displaying educational content in 3D virtual worlds. The model suggests conducting image-processing tasks on stream processors in order to reduce the load on CPU. It allows designing convenient and sophisticated tools for collaborative work with graphics inside a 3D environment. Such tools simplify the use of a 3D virtual environment, and therefore, improve the negative learning curve effect. We present the methods of generating images based on the suggested model, the design and implementation of a set of tools for collaborative work with 2D graphical content in vAcademia virtual world. In addition, we provide the evaluation of the suggested model based on a series of tests which we applied to the whole system and specific algorithms. We also present the initial result of user evaluation.

Virtual training and research laboratory of technological processes of chemical-technological systems

“…Virtual environment vAcademia is an educational three-dimensional virtual world, which in comparison with other virtual worlds has two main advantages [1][2][3][4]9]:  vAcademia is a specialized world for education, which means that it has everything that is necessary for the teacher and students in the classroom: interactive whiteboards, overhead projectors, pointers, Webcams, survey systems, models of educational objects, etc. ;  vAcademia has an ability to record classes.…”

Fusion of Smart, Multimedia and Computer Gaming Technologies

“…In order to formalize the domain, a mathematical model of image processing by the SPs has been developed based on the specifics of the SP architecture and hardware constraints. The mathematical apparatus of processing 3D graphics by the SPs was simplified to focus only on processing images [51,52].…”

Collaborative work with large amount of graphical content in a 3D virtual world: Evaluation of learning tools in vAcademia

“…We suggest a method for collaborative work with large amount of graphical content in 3D virtual worlds. The method is based on a mathematical and a programming model for texture generation [7], based on stream processors (SPs) [8]. The model allows us to pass the calculations of graphics on to the stream processors in order to reduce the load on CPU.…”
