      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.

  1. Thanks for the input! I haven't figured out how to get the D3D debug info to show in the output window (I've had it there before, so I'm not sure what happened...) At any rate I used PIX to get the debug output and got the problem figured out. It was [font="Consolas,"]GeometryShader.NoRasterizedStream[/font] ..... Apparently that only works with D3D11 feature level. I've got a 10.1 card so there has to be a rasterized stream set. I changed it to 0 and it works fine.
  2. I'm trying to recreate the NVidia Cascades demo (sort of) using SlimDX and D3D11 but I keep running into a problem on creating the geometry shaders with stream output. I'm running the debug runtime, but I'm not seeing any output from that. The only thing I get in the VS output window is: A first chance exception of type 'SlimDX.Direct3D11.Direct3D11Exception' occurred in SlimDX.dll The unhandled exception window shows up and tells me that the error was an E_INVALIDARG. Which usually indicates an error on the stream output declaration, but I can't for the life of me see what that would be. Any help would be greatly appreciated! My stream output declaration: [source] var sElement = new StreamOutputElement[] { new StreamOutputElement(0, "POSITION", 0, 0, 1, 0), }; [/source] Bytecode and geometry shader creation code: [source] bytecode = ShaderBytecode.CompileFromFile(StringTable.ShaderPath + "list_nonempty.gs", "GS", "gs_4_1", ShaderFlags.Debug, EffectFlags.None, null, includeHandler, out error); gShader = new GeometryShader(device, bytecode, sElement, new int[] { 4 }, GeometryShader.NoRasterizedStream); [/source] And my geometry shader code: [source] struct vs_to_gs { uint z8_y8_x8_case8 : OUTPUT; }; struct gs_to_app { uint z8_y8_x8_case8 : POSITION; }; [maxvertexcount(1)] void GS(point vs_to_gs input[1], inout PointStream<gs_to_app> Stream) { // pull the case out of the input uint cube_case = input[0].z8_y8_x8_case8 & 0xFF; // check that the case is not 0 if(cube_case * (255 - cube_case) > 0) { // if the case is not zero add this voxel to the output stream gs_to_app output; output.z8_y8_x8_case8 = input[0].z8_y8_x8_case8; Stream.Append(output); } } [/source]
