OpenGL ES is the standard graphics API used for mobile and embedded systems. Despite its widespread use, there is a lack of material that addresses the balance of both theory and practice in OpenGL ES. JungHyun Han Introduction to computergraphics with OpenGL ES achieves this perfect balance. Han depiction of theory and practice illustrates how 3D graphics fundamentals are implemented. Theoretical or mathematical details around real-time graphics are also presented in a way that allows readers to quickly move on to practical programming. Additionally, this book presents OpenGL ES and shader code on many topics. Industry professionals, as well as, students in computergraphics and Game Programming courses will find this book of *** Features: Presents key graphics algorithms that are commonly employed by state-of-the-art game engines and 3D user interfaces Provides a hands-on look at real-time graphics by illustrating OpenGL ES and shader code on various topics Depicts troublesome concepts using elaborate 3D illustrations so that they can be easily absorbedIncludes problem sets, solutions manual, and lecture notes for those wishing to use this book as a course text.

Path generation is an important problem in many fields, especially robotics. One way to create a path between a source point z and a target point y inside a complex planar domain is to define a non-negative distance function d(y, z), such that following the negative gradient of d (by z) traces out such a path. This presents two challenges: (1) The mathematical challenge of defining d, such that d(y, z) has a single minimum at z = y for any fixed y, because the gradient-descent path may otherwise terminate at a local minimum before reaching y;(2) The computational challenge of defining d, such that it can be computed efficiently. Using the concepts of harmonic measure and f-divergence, we show how to assign a set of reduced coordinates to each point in and to define a family of distance functions based on these coordinates, such that both the mathematical and the computational challenge are met. Since in practice, especially in robotics applications, the path is often restricted to follow the edges of a discrete network defined on a finite set of sites sampled from , any method that works well in the continuous setting must be discretized appropriately to preserve the important properties of the continuous case. We show how to define a network connecting a finite set of sites, such that a greedy routing algorithm, which is the discrete equivalent of continuous gradient descent, based on our reduced coordinates is guaranteed to generate a path in the network between any two sites. In many cases, this network is close to a planar graph, especially if the set of sites is dense. Guaranteeing the existence of a greedy route between any two points in the graph is a significant advantage in practical applications, avoiding the complexity of other path-planning methods, such as the shortest-path and A* algorithms. While the paths generated by our algorithm are not the shortest possible, in practice we found that they are close to that.
In the present paper, questions of development of the theory and expansion of areas of practical application of one of the classical methods of geometric modelling - cyclography - are considered. Briefly given known b...

The field of computer information technologies in general, and more specifically that of network switching and routing, is filled with abstractions, abbreviations, and acronyms, along with an accompanying assortment of implementation techniques frequently requiring customization. Bridging the divide between theory and practice can be difficult for students as they attempt to build a cohesive understanding of the subject. It also poses a challenge for faculty trying to convey dense, text-heavy technical information using either the conventional chalkboard or presentation software. It is easy for the underlying beauty of the concepts to stay hidden under the jargon-filled landscape. Notes written on the whiteboard or chalkboard by faculty focus on conveying technical content to students, and these may make only limited used of graphical design ideas that can be leveraged for communicating information more effectively. What is needed is a mechanism for engaging both the students' imagination and technical skills while building an understanding of concepts, using technology appropriately, solving technical issues safely, and focusing on the process along the way. Exploring network switching and routing can be facilitated using the elements and the principles of graphic design. The strategic use of icons, symbols, color, scale, proximity, contrast, groupings, hierarchy, alignment, repetition, balance, along with text annotations in diagrams or tables as part of Boardnotes 2.0, aims to do just that. The repeated usage of these elements encourages students to develop a visual vocabulary of the subject, using both standardized and self-developed graphics as a way for firming up ones understanding about a topic. Boardnotes 2.0 refers to the thoughtful use of selected graphical design elements and principles while communicating technical information using a whiteboard or chalkboard.
