      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.

Basic Shadow Mapping Depth Stencil Question

0 posts in this topic

After Spending about 3 days trying to get shadow mapping to work I'm having some trouble getting the shadow mapped passed in to the shaders.


First I initialize the depth stencil and the resource view, then i draw ( I believe ) to the depth stencil. The problem that I am finding is that the depth stencil never has any data associated with it.


Pix shows no data in the resource view or the depth stencil, I am unable to save an image of the depth stencil to a file (I am from the non shadow depth stencil ). I am able to call DrawSceneShadow() and see a result I want though.


Any help is appreciated thank you.




    // Create depth stencil texture
    D3D10_TEXTURE2D_DESC descDepth;
    descDepth.Width = width;
    descDepth.Height = height;
    descDepth.MipLevels = 1;
    descDepth.ArraySize = 1;
    descDepth.Format = DXGI_FORMAT_R32_TYPELESS;
    descDepth.SampleDesc.Count = 1;
    descDepth.SampleDesc.Quality = 0;
    descDepth.Usage = D3D10_USAGE_DEFAULT;
    descDepth.BindFlags = D3D10_BIND_DEPTH_STENCIL;
    descDepth.CPUAccessFlags = 0;
    descDepth.MiscFlags = 0;
    hr = g_pd3dDevice->CreateTexture2D( &descDepth, NULL, &g_pDepthStencil );
    // Create the depth stencil view
    descDSV.Format = DXGI_FORMAT_D32_FLOAT;
    descDSV.ViewDimension = D3D10_DSV_DIMENSION_TEXTURE2D;
    descDSV.Texture2D.MipSlice = 0;
    hr = g_pd3dDevice->CreateDepthStencilView( g_pDepthStencil, &descDSV, &g_pDepthStencilView );
    //Shadow Mapping
    //create shadow map texture desc
    descDepth.Width = width;
    descDepth.Height = height;
    descDepth.Format = DXGI_FORMAT_R32_TYPELESS;
    //create shader resource view desc
    srvDesc.Format = DXGI_FORMAT_R32_FLOAT;
    srvDesc.ViewDimension = D3D10_SRV_DIMENSION_TEXTURE2D;
    srvDesc.Texture2D.MipLevels = descDepth.MipLevels;
    srvDesc.Texture2D.MostDetailedMip = 0;
Render Scene
//Create shadow map
    //set render targets
    //set render targets and viewport
    g_pd3dDevice->OMSetRenderTargets(0, 0, pShadowMapDepthView);
    g_pd3dDevice->ClearDepthStencilView( pShadowMapDepthView, D3D10_CLEAR_DEPTH, 1.0f, 0 );
    moveCam( lightPos.x, lightPos.y, lightPos.z );
    //Render final scene
    //set render targets
    g_pd3dDevice->OMSetRenderTargets(1, &g_pRenderTargetView, g_pDepthStencilView);    
    g_pd3dDevice->RSSetViewports(1, &vp);
    g_pd3dDevice->ClearRenderTargetView( g_pRenderTargetView, D3DXCOLOR(0.6f,0.6f,0.6f,0) );
    g_pd3dDevice->ClearDepthStencilView( g_pDepthStencilView, D3D10_CLEAR_DEPTH, 1.0f, 0 );
    //bind shadow map texture
    g_pEffect->GetVariableByName("shadowMap")->AsShaderResource()->SetResource( pShadowMapSRView );
    //unbind shadow map as SRV and call apply on scene rendering technique
    g_pEffect->GetVariableByName("shadowMap")->AsShaderResource()->SetResource( 0 );
    g_pRenderShadowMapTechnique->GetPassByIndex(0)->Apply( 0 );
