      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.

Parsing Models with Multiple Textures

4 posts in this topic

So I'm working on a graphics project for school and I got model loading set up a few weeks ago. Essentially I used lib3ds to get a list of all of the vertices of a model and then render them. This works fine for models with a single texture. My question is how should I go about managing models with more than one texture? Is there a common system in .3ds files for such a thing? Like is it a per mesh assignment? It seems like if each mesh was assigned a texture then doing this would not be a big deal, just a matter of rebinding the texture when the next mesh's vertices come along.

If this isn't possible or practical that's fine too. For the scope of this project single texture models will work, I just want to get fancy if I can.

I've never worked with lib3ds so I can't advise, but you may want to ask in the graphics programming forum. I'd be amazed if there weren't a simple way to do so.

[indent=1]While I can't speak to the specific library, your per-mesh idea is what I would recommend with any 3d library. If a "model" is just composed of 1 to n meshes, each mesh can have its own texture, refer to the same texture, etc paralleling the "materials" concept seen in most modeling tools. It's just up to you to then improve efficiency through things like material-based batching (to reduce the number of rebindings needed to render a multi-material or multi-texture scene).[/indent]

Is there a way to move this such that there isn't a duplicate?
