The GameDev.net FreeBook is relevant to game designers, developers, and those interested in learning more about the challenges in game development. We know game development can be a tough discipline and business, so we picked several chapters from CRC Press titles that we thought would be of interest to you, the GameDev.net audience, in your journey to design, develop, and market your next game. 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.

OpenGL ES on desktops

10 posts in this topic

Is there a way to use opengl es 2 on desktops natively? I have tried searching google and found alot to do with the android emulator but not much about gles2 on windows I found mesagles that maybe a solution for linux. I would think theres got to be something how do browsers use webgl?

Is there a way to do it in reverse so something already existing using opengl can run in a browser or mobile with opengles? Is there a higher language that could be used across everything? Do developers usually make multiple shaders for multiple targets?

We run the same render path for desktop and mobile GL. I have a "proxy" header, which defines functions like gl::Clear, gl::VertexAttribPointer, etc instead. The proxy changes a few function names as needed, and a few things are switched on either compile or runtime flags. (Not many things.) I don't try to fully emulate correct GL ES behavior on desktop; I just want my ES code to run. This proxy does that and works across Windows, Linux, Mac, and iOS. 

 

As for shaders, I found that trying to share them across desktop and mobile was a catastrophe. I now use hlsl2glsl (linked above) with some custom patches for full Mac and ES support. I should remember to assemble those changes into a pull request some day.

You might want to try out Emscripten. It compiles fairly typical C/C++ OpenGL code to Javascript / WebGL (WebGL is a subset of OpenGL ES).

You might also like to have a look at PVRVFrame which is part of the Imagination Technologies PowerVR SDK (http://www.imgtec.com/tools/powervr-tools/). We had a talk from these guys at work and these tools certainly looked useful. Edited by Karsten_
