Designing an interactive OpenGL slide-based presentation of the softbody simulation system for teaching and learning of computer graphics techniques

Abstract

3D graphics power-point-like slides in OpenGL is a way to present a demo or a teaching item. We focus on how the softbody objects are modeled and rendered with the intent to make a base for teaching, learning, and education of/for computer graphics and integration with the softbody framework. This is work-in-progress on the implementation and publication of this integration and demonstration work.

Teaching Physical Based Animation via OpenGL Slides

“…The major pieces of the related work that contribute to this works, are two frameworks alongside with their implementation, put together with other items, to eventually form a teaching module for computer graphics. Here we extrapolate from our previous poster presentation [17] on this topic with more details on the actual design and implementation of the physical-based softbody animation techniques in an OpenGL power-point-like presentation tool with the demonstrated results. We describe the two CG systems in this section in some detail for the unaware reader.…”

“…The Integrator API of the framework as of this writing is implemented by the well-known Explicit Euler, Midpoint, Feynman, and Runge-Kutta 4 (RK4)-based integrators for their mutual comparison of the run-time and accuracy. The system is implemented using OpenGL [8,22] and the C++ programming language with the object oriented programming paradigm [17]. This elastic object simulation system has been designed and implemented according to the well known architectural pattern, the model-view-controller (MVC).…”

“…Each slide is a derivative of the generic Slide class and represents a scene with the default keyboard controls for the tidgets and navigation. It is understood that the tidgets can be enabled and disabled to allow the main animation to run unobstructed [6,7,17]. Each scene on the slide is modeled using traditional procedural modeling techniques [21] and is set as a developer or artist desires.…”

CGLT: An Effective Computer-Based Learning Tool

“…The attraction in choosing computer graphics is its challenging nature that still cannot be properly presented with traditional teaching ways. However, different computer-based educational tools have been created to facilitate teaching computer graphics [4,5].…”

“…Teaching scientific principles through a computer-based learning environment is presented in [13]. Song et al in [5] designed an interactive OpenGL slide-based simulation tool for teaching and learning computer graphics techniques. In [14], a study is presented on the effects of CAI on the mathematics performance of students with learning disabilities.…”
