The free ebook is available through CRC Press by clicking here. The Curated Books The Art of Game Design: A Book of Lenses, Second Edition, by Jesse Schell Presents 100+ sets of questions, or different lenses, for viewing a game’s design, encompassing diverse fields such as psychology, architecture, music, film, software engineering, theme park design, mathematics, anthropology, and more. Written by one of the world's top game designers, this book describes the deepest and most fundamental principles of game design, demonstrating how tactics used in board, card, and athletic games also work in video games. It provides practical instruction on creating world-class games that will be played again and again. View it here. A Practical Guide to Indie Game Marketing, by Joel Dreskin Marketing is an essential but too frequently overlooked or minimized component of the release plan for indie games. A Practical Guide to Indie Game Marketing provides you with the tools needed to build visibility and sell your indie games. With special focus on those developers with small budgets and limited staff and resources, this book is packed with tangible recommendations and techniques that you can put to use immediately. As a seasoned professional of the indie game arena, author Joel Dreskin gives you insight into practical, real-world experiences of marketing numerous successful games and also provides stories of the failures. View it here. An Architectural Approach to Level Design This is one of the first books to integrate architectural and spatial design theory with the field of level design. The book presents architectural techniques and theories for level designers to use in their own work. It connects architecture and level design in different ways that address the practical elements of how designers construct space and the experiential elements of how and why humans interact with this space. Throughout the text, readers learn skills for spatial layout, evoking emotion through gamespaces, and creating better levels through architectural theory. View it here.

Augmented Reality example in Python

2 posts in this topic

Hello,

two years ago, when I was experimenting with python and pygame, I've stumbled upon pygame's camera module and decided to write some kind of a simple augmented reality application (like [b]Microsoft's Kinect[/b], but much simplier) to have some programming practice. After a few dedicated days, I've finally completed it. [b]AR example[/b] targets an object with a marker and allows you to interact with virtual objects: bouncing balls, button-like interface elements, etc. Here is a screenshot:

[img]http://pygame.org/thumb/44b802581a8001bad884ad59cb5efcae.png[/img]

You can run it under Linux and Windows (not sure about OSX) out of the box. It requires python 2.5.x-2.7.x and pygame 1.9.x.

[b]AR example for Window and Linux[/b]: [url="https://bitbucket.org/slmgc/ar-example/downloads/ar-example-0.3.1.zip"]https://bitbucket.or...ample-0.3.1.zip[/url]
Just install python and pygame [b](windows users don't need pygame[/b], I've included pygame into the package), unpack ar-example-0.3.1.zip into some folder and click on "augmented.py" to run the program.

[b]ActivePython 2.7 for Windows[/b]: [url="http://www.activestate.com/activepython/downloads/thank-you?dl=http://downloads.activestate.com/ActivePython/releases/2.7.2.5/ActivePython-2.7.2.5-win32-x86.msi"]http://downloads.act...5-win32-x86.msi[/url]

[b]Instruction[/b]:[list=1]
[*]Take an object of a simple shape and solid color.
[*]Fixate an object's color in a color picker.
[*]Change the chosen color's RGB components so only the targeted object would be visible on screen.
[*]After you are ready, switch from the calibration to the targeting mode.
[*]If the result is not good enough, switch back to the calibration mode and repeat the above steps.
[/list]

Program's source code is under GPL 2. VideoCapture by Markus Gritsch is under LGPL 2.1.

P.S. A couple of days ago I've decided to write a new version of AR example using proper techniques such as: modular design, event-driven architecture with loosely-coupled components, multithreading, separate config file, etc. New source code is under public domain.

If you are interested, you can get AR example's source code from my project's page at pygame.org: [url="http://pygame.org/project-AR+example-1622-.html"]http://pygame.org/pr...mple-1622-.html[/url]
Or you can grab it directly from my mercurial repository at bitbucket: [url="https://bitbucket.org/slmgc/ar-example"]https://bitbucket.org/slmgc/ar-example[/url]

P.P.S. Any feedback, questions, suggestions are most welcomed. Edited by slmgc

I've added direct links for [b]python[/b] and [b]pygame for Windows[/b] to run the program.

I've [b]added pygame[/b] library to the package for [b]windows users[/b], so they don't need to download it to run AR example, [b]just install python 2.7[/b]
