There are many impressive games that have been created with OpenGL, such as Doom3, Counter-Strike, various Medal of Honor, Need for Speed and many others. This book will provide you with the basics to start your own OpenGL core projects on Xojo. Watch the video clips below!

OpenGL is one of the few standards for creating a powerful software interface. There is a great deal of reusable code and material on the internet that can be adapted to Xojo. Another resource with free examples is at Alwyn Bester's website at Xojo3D.com

This book builds a strong foundation on programming graphics. This is an advanced graphics book and it is highly recommended to understand the Xojo programming language first. An intermediate book called "I Wish I Knew How to... Program the Canvas Control with Xojo Desktop" is a good book to study and understand before learning OpenGL. Examples in this book have been created and tested on Windows 10 and OSX El Capitan operating systems. This book is focused on 32-bit programming. Much of the code works with a timer to provide smooth graphics and animation. Below are a few video's of examples that are included in this book. These examples are currently 32-bit.

WMICHas someone ever asked you the question "Is my computer 32-bit or 64-bit"? WMIC is the command that can retrieve this information about a Windows Operating System and almost all of the components installed on the computer. WMIC is the abbreviation for Windows Management Instrumentation Command-Line that has been used for over a decade in the Windows OS.

The book "I Wish I Knew How To...Program Windows WMIC With Xojo" is able to query hundreds of parameters on the computer and this code can be implemented into your program. This is a reference book that shows the many possible options of WMIC and retrieves data seamlessly to your program. 

The most difficult part of working with WMIC is to provide the correct search parameters, which this book covers in all of these chapters.

stepYou can do many things with the Raspberry Pi, and some have built a Star Trek interface, while others have built robots. This book provides the building block to work with Xojo to react with the real world through its motherboard to allow you to make your own interesting device. This inexpensive computer can be programed by the widely recognized Xojo programming language.
