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.

Open Gl question

7 posts in this topic

Well, you problem is probably your drivers. Unless you have the OpenGl beta drivers for your card (you can get them at www.3dfx.com) you ARE using software rasterization. In fact you are using microsofts implimentation which is particuarly slow. I have a TNT2 and NeHe's examples run like a dream on my system.

Hope that helps,
Nomad

Im a newbie in open gl programming I began using the nehe tutorial from opengl.org and compiled it with microsoft opengl, and the result was sloooow, really slow about 5 fps
I mean, come on I can make a software rasterizer in quickbasic faster than that.
I have a banshee 3d card and I expected enormously better results, specially after seing quake 3 what Im I doing wrong?

Happy new century everyone!

Even with drivers will a 3Dfx cards still be slow for opengl.
Quake use it''s own version of opengl quakGL.And quakGL is standart supported by 3Dfx.

I use a TNT2 and I have no performance problem.

Nehe codes are great, but not written to use hardware acceleration of Voodoo boards.

There are drivers for Mesa3d (variant of OpenGL) that does openGL1.2 features. Mesa3d drives are also available for other platforms, and works for all glide compatible hardware.

What about mini-gl? when I went to 3dfx.com I saw that there is a minigl driver, however there is no SDK or tutorials, where can I find info about it?

QuakeGl? (pseudo stupid question coming up) is this implementation available somewhere? where can you find more info about it? :)

MiniGL accelerates only a handful of OpenGL functions. MiniGL was written by 3Dfx for Quake/2/3 games so people could run those games on 3Dfx hardware. I don''t know if there is a full ICD available for voodoo/banshee cards, and if yes than the ICD will get only better in the future since now 3Dfx dumped Glide and will concentrate on OpenGL and D3D drivers. Nehe''s tutorials may require you to have full ICD installed, but I might be wrong. When your card doesn''t support one of the features of the game in hardware then it reverts to software mode.

Hi (first... sorry ''bout my bad english *g*)

I''ve a Riv128 and still the same problem and I''m a newbie, too *g*. I want to program a little game wich used openGL. In my case the game is a PBeM (Play by eMail), so many users with different hardware are using the Gamefile.
My questions:
a) Where can I get the dll''s for my Card and
b) is there a way to make the program fast (I mean for every platform)
optional c) how is it in Linux/Mac etc???

so long

I have a Voodoo 3, and Nehe's tutorials run just fine on my computer. I'm running NT 4 with the newest drivers, and everything's peachy.

One thing you need to do is make sure your desktop is set to 16-bit color when running OpenGL stuff on a 3dfx card. They don't support acceleration at higher bit depths.
