      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.

Useful things you might want to know about FBXSDK

7 posts in this topic

This might be quite useful. You should think about posting this as an article (Menu->Articles->Post an Article).
 Good work.

Thanks, this article certainly helped me with my fbx converter.

However, I noted that you extract the vertex information into seperate vertices, without checking for duplicates and such; therefore leading to unoptimized meshes. How feasible would it be if I use the addresses to the source data as comparison for duplicate vertex information?

Hi. I actually handled the duplicate vertices. You can access my entire project(through my git repo) at this article: http://www.gamedev.net/page/resources/_/technical/graphics-programming-and-theory/how-to-work-with-fbx-sdk-r3582.

The de-dup process is straightforward but in my opinion it might not be the most efficient one. 

Please let me know if you can figure out a better method.

Not trying to capture the thread, but how easy/feasible would it be to parse ASCII FBX manually without SDK? Does the format change often, any potential pitfalls etc.?

Well. I think ASCII FBX changed before, but don't quote me on that.

I am not sure why you would want to parse it directly instead of using the SDK.

It is definitely feasible.....but not easy.....

Plus, if you use the SDK, when Autodesk decides to change something, probably at worst you need to refactor/change some API calls, but if you parse it yourself, each time they change something, it is gonna be a huge pain.

 

Personally I do not recommend it.

Ok, I think i'll go with the SDK for now. The reason I asked was because I want to keep my dependencies to the minimum in cases where doing things by myself is doable quality/time-wise.
