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.

How to dither to a 24/32 bit surface in DirectX/SlimDX

0 posts in this topic

I Basically what I am trying to do is be able to display a red (or green or blue) letter with more then 256 possible shades. For example normally if I have a blue letter 'A' with an rgb value of (0 , 0 , 100) the next blue level up would be an rgb (0, 0 , 101). I want to be to show an 'A' that "APPEARS" to have an rgb value of (0, 0, 100.25). Basically I want to do this by making 3/4th of the pixels in the "A" have (0,0,100) and 1/4th have a value of (0,0,101). I noticed that there is a dither filter in DX but from reading about it I don't think it is quite what I want but I am not sure. The reason I don't think I can use the built in dithering is because from what I have read here: [url="http://www.toymaker.info/Games/html/render_states.html#blends"]http://www.toymaker.info/Games/html/render_states.html#blends[/url] the built in dithering is legacy code that only works when rendering to a 16bit surface. I need a way to dither from a pixel format that is > 8bits per channel down to 8bits per channel. Does any one know of a way I could implement this dithering. I don't know anything about writing pixel shaders but do you think that might be the right approach? If I could figure out a way to determine which pixels made up the letter I would could try a simple dithering technique where I just go through each pixel and based on a 25% probability bump the color up one but this would be less then ideal. Does anyone have any experience with dithering in DirectX and know of any techniques that would make this possible.

NOTE: I am using SlimDX (DX9) but could switch to DX10/11 if needed
