Essential Guide to RenderMan® Shading Plugin Development: Understanding Bxdfs
by Brad E. HollisterUnderstand the fundamentals of Bxdf plugins for RenderMan® 21+, both the technical details and API architecture. The main goal of the book is to enable technical artists, hobbyists, and students in using the noncommercial (NCR), free RenderMan® edition. RenderMan® is an industry standard for rendering software. It has been used for every Pixar film to date and numerous other projects. RenderMan® 21, and all subsequent versions, use Monte Carlo path tracing. This change has necessitated the use of C++ plugins in place of the RenderMan Shader Language (RSL). Because of this, writing Bxdfs now requires knowledge of Monte Carlo integration, probability density functions, and the RenderMan® C++ API. Essential Guide to RenderMan® Shading Plugin Development specifically addresses writing RenderMan® C++ materials. It explores the mathematical models of representative Bxdfs while drawing parallels, when helpful, to earlier RSL implementations. It also includes an overview of Integrators, providing further context for modern RenderMan® programmable shading. What You Will LearnC++ development for BxdfsFundamentals of the rendering equationMonte Carlo integration Who Is This Book ForBeginner plugin writers for RenderMan®, such as technical artists, students, or hobbyists who may already have experience with RSL or another shader language. More experienced C++ developers without knowledge of RenderMan® or Monte Carlo path tracing will benefit from the content as well. While some prior experience in computer graphics is helpful, the book provides background and references for further study.
Essential Java for AP CompSci: From Programming to Computer Science
by Doug WinnieGain the essential skills for computer science using one of today's most popular programming languages, Java. This book will prepare you for AP CompSci Complete, but you don’t need to be sitting that class to benefit. Computer science has become a basic life skill that everyone is going to need to learn. Whether you are going into a career or side hustle in business, technology, creativity, architecture, or almost any other field, you will find coding and computer science play a role. So when we learn programming we are going to focus on three things: what is the process; what is the syntax; and what is the flow. The process is represented as a flowchart. We will learn how to make these to help you plan out what you are going to do before you write a line of code. At first, the flowcharts will be pretty simple, but then they will get more complex. The syntax is the code: this is what you write that translates the process you create in a flowchart to the instructions that the computer can understand. Finally, there is the flow. This is where you trace through the code and see how the data and information it stores along the way changes. You can see how the operation of the program cascades from line to line. You will be building charts that will capture the programming flow so you can better understand how the computer processes code to make your next program easier to conceive and code.Along the way to aid in the learning of the essential Java skills, there will be three kinds of project types throughout this book: business software projects for applications where you work for a company and need to complete an internal project for a team such as the sales, marketing, or data science teams; social good projects where you are working for non-profits or for agencies that are trying to research and provide solutions to economic, environmental, medical, or humanitarian projects; and game development projects for games based on player input, random chance, or other mechanics for the use of entertainment.What is unique about computer science is how it has become a skill, and not just a career. While there are jobs and titles of “computer scientist”, the skill of computer science, and specifically programming, are almost everywhere. After reading and using this book, you'll have the essential skills to think like a computer scientist, even if you are not. As a result you’ll be of greater value to your clients, your company, and yourself. What You Will Learn Discover the primary building blocks of programming using the Java programming language See terminology and best practices of software development Work with object-oriented programming concepts Use common-language definitions and examples to help drive understanding and comprehension of computer science fundamentals Who This Book Is For Those who want to learn programming and want to think like a computer scientist. Ideal for anyone taking AP CompSci Complete.
Essential Logic for Computer Science
by Ruben Gamboa Rex PageAn introduction to applying predicate logic to testing and verification of software and digital circuits that focuses on applications rather than theory. Computer scientists use logic for testing and verification of software and digital circuits, but many computer science students study logic only in the context of traditional mathematics, encountering the subject in a few lectures and a handful of problem sets in a discrete math course. This book offers a more substantive and rigorous approach to logic that focuses on applications in computer science. Topics covered include predicate logic, equation-based software, automated testing and theorem proving, and large-scale computation. Formalism is emphasized, and the book employs three formal notations: traditional algebraic formulas of propositional and predicate logic; digital circuit diagrams; and the widely used partially automated theorem prover, ACL2, which provides an accessible introduction to mechanized formalism. For readers who want to see formalization in action, the text presents examples using Proof Pad, a lightweight ACL2 environment. Readers will not become ALC2 experts, but will learn how mechanized logic can benefit software and hardware engineers. In addition, 180 exercises, some of them extremely challenging, offer opportunities for problem solving. There are no prerequisites beyond high school algebra. Programming experience is not required to understand the book's equation-based approach. The book can be used in undergraduate courses in logic for computer science and introduction to computer science and in math courses for computer science students.

Essential Python for the Physicist
by Giovanni MoruzziThis book introduces the reader with little or no previous computer-programming experience to the Python programming language of interest for a physicist or a natural-sciences student. The book starts with basic interactive Python in order to acquire an introductory familiarity with the language, than tackle Python scripts (programs) of increasing complexity, that the reader is invited to run on her/his computer. All program listings are discussed in detail, and the reader is invited to experiment on what happens if some code lines are modified. The reader is introduced to Matplotlib graphics for the generation of figures representing data and function plots and, for instance, field lines. Animated function plots are also considered. A chapter is dedicated to the numerical solution of algebraic and transcendental equations, the basic mathematical principles are discussed and the available Python tools for the solution are presented. A further chapter is dedicated to the numerical solution of ordinary differential equations. This is of vital importance for the physicist, since differential equations are at the base of both classical physics (Newton’s equations) and quantum mechanics (Schroedinger’s equation). The shooting method for the numerical solution of ordinary differential equations with boundary conditions at two boundaries is also presented. Python programs for the solution of two quantum-mechanics problems are discussed as examples. Two chapters are dedicated to Tkinter graphics, which gives the user more freedom than Matplotlib, and to Tkinter animation. Programs displaying the animation of physical problems involving the solution of ordinary differential equations (for which in most cases there is no algebraic solution) in real time are presented and discussed. Finally, 3D animation is presented with Vpython.
Essential SNMP, 2nd Edition
by Douglas Mauro Kevin SchmidtSimple Network Management Protocol (SNMP) provides a "simple" set of operations that allows you to more easily monitor and manage network devices like routers, switches, servers, printers, and more. The information you can monitor with SNMP is wide-ranging--from standard items, like the amount of traffic flowing into an interface, to far more esoteric items, like the air temperature inside a router. In spite of its name, though, SNMP is not especially simple to learn. O'Reilly has answered the call for help with a practical introduction that shows how to install, configure, and manage SNMP. Written for network and system administrators, the book introduces the basics of SNMP and then offers a technical background on how to use it effectively. Essential SNMP explores both commercial and open source packages, and elements like OIDs, MIBs, community strings, and traps are covered in depth. The book contains five new chapters and various updates throughout. Other new topics include: Expanded coverage of SNMPv1, SNMPv2, and SNMPv3 Expanded coverage of SNMPc The concepts behind network management and change management RRDTool and Cricket The use of scripts for a variety of tasks How Java can be used to create SNMP applications Net-SNMP's Perl module The bulk of the book is devoted to discussing, with real examples, how to use SNMP for system and network administration tasks. Administrators will come away with ideas for writing scripts to help them manage their networks, create managed objects, and extend the operation of SNMP agents. Once demystified, SNMP is much more accessible. If you're looking for a way to more easily manage your network, look no further than Essential SNMP, 2nd Edition .
