      Download the Game Design and Indie Game Marketing Freebook   07/19/17

      GameDev.net and CRC Press have teamed up to bring a free ebook of content curated from top titles published by CRC Press. The freebook, Practices of Game Design & Indie Game Marketing, includes chapters from The Art of Game Design: A Book of Lenses, A Practical Guide to Indie Game Marketing, and An Architectural Approach to Level Design. 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.

3d math

hello. First of all, great forum. I love math and physics, but I haven''t had that many classes yet, i mean as far as the level of game development, I just finished geometry in high school and i''m going to algebra 2, but i have done a little learning on my own since i''m not there yet, well i want to do some more learning on my own. I was just wondering if there were any books you guys thought were good that explained 3d math on a somewhat simplistic level. I am trying to learn 3d programming, I could do some now, but I want some more in depth information. If you know of any good links or books please post them.

To get sufficient knowledge of the mathematical topics used in 3D games programming, you''ll want to take a look at a 1st year University level text on Calculus & Analytic Geometry. You''ll also need an introductory text on Linear Algebra.

Pretty much anything being used as a text book for such classes will suffice for your needs.

Good luck.

Pre-Calculus (Trigonometry) should be your first step. I learned everything about 2D from that.

Going straight to 3D will probably overwhelm you as there''s no simple way to explain it. You can find some BASIC programs I wrote using 2D and 3D math at my site.

u might want to pick up a a book like practical trigonomitry
or any 3d game programing book will have most of the basic concepts

Although this post is old, I thought I''d make a suggestion in case anyone is still checking it.

The book "3D Graphics Programming: Games and Beyond" by Sergei Savchenko (spelling?) is a good book that explains the basics of 3D math and graphics programming in clear language.

The only thing to watch out for is typos in some of the derivations, but all the final equations are correct, and the typos just give incentive to derive the equations for yourself and truly understand them

So if you want a book that''s not pure math, but 3d math applied to [software] 3D graphics programming then check this out. It''s cheaper than most programming books.

It also comes with code for displaying 3d objects and stuff.

Good luck!

I learned Bresenham''s algorithm, the inside tests Even-Odd and Winding Number, 3D matrix transformation and projection, 2D and 3D clipping from a wonderful little book titled Computer graphics: A Programming Approach by Steven Harrington. It''s second edition was publihsed in 1987; I don''t know if it''s been updated, so it may be hard to find. The book really shines because of its algorithm-intensive approach and deliberate languages independence. All algorithms are stated in a pseudocode syntax that translates well to any language (it''s somewhat similar to ALGOL). Also, if you can find it it''ll be dirt cheap. It covers a lot of stuff modern books don''t because it was written before the advent of the hardware renderer.

Heartily recommended.
