      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.

  1. First of all, thx for response.The project is just a one man show and i never learned the graphic and directx stuff professionally. It's just fun and hobby. I was proud about that nice video result, so i wanted to share it. Sorry about the wrong section. Technical details ? On the Blog you can download a realtime demo (no sound, including source) and i added some infos to the engine-section about the shader. Or what technical interests do you have? I could add it. And yes.. the ugly color-bending is still a problem. I have experimented with noise, but still not lucky with the result.
  2. I have implemented some new PlanetShader, Bloom, Skyboxing and a better Glow. Watch the new Video and/or Download a running Demo from the VBexEngine Blog. Have Fun !
  3. VBexEngine Here is a new video about the implemented reflected material (Deferred Planar Reflections). Take a look and have fun... :wink:   https://youtu.be/9PGfwCsi9vc ProjectBlog: https://vbexengineblog.wordpress.com/
  4. So here is the first downloadable demo-scene of my Engine-Project. It's just a very simple Demo that show's how easy it is to implement the engine. It's testet on Windows10 / Nvidia GTX1070 / AMD4500HD. .. give it a try. I am glad about every feedback if everything is running or not .   SlimDX runtimes (32 and 64) must be installed. (Microsoft .NET Framework 4.6)   Blog:https://vbexengineblog.wordpress.com/2016/12/30/basic-scene/
  5. If your Christmas tree is not decorated yet .. have a look to my Engine-Test Video  :) I wish you a Merry Christmas... Have fun and keep coding! https://youtu.be/eAaCevQmbh4     Blog: https://vbexengineblog.wordpress.com
  6. Yes that's right...  but I think my English is to bad to write all the stuff down correctly...
  7. I've Updatet my Engine and Editor-Project using SlimDX and VBnet. Have a look if you'e interested... :)   NiceVideo: https://youtu.be/8WW3Acl7qCQ   ProjectPage: https://vbexengineblog.wordpress.com/
  8. ok.. i can't get it to work like that.. so my way: - save viewpos.z to R32_Float Target - Draw Fullscreenquad\Triangle and get ViewVec (multiply position * InvProjection in VertexShader) - Scale ViewVec by saved viewpos.z That's it ! so i'm moving light calculation to ViewSpace.. that's easy and cheap.. multiply ViewPos with InvViewMatrix to get WorldPosition
  9. Somthing is wrong..  but i don't know what....  -store WorldViewDistance to R32_F -Fullscreen Quad (Positions x InvViewProjection)-WorldCamPos to get WorldRay (I'm Using Fullscreen Triangle) -Normalize Ray -Scale Ray by Distance from R32_F -add WorldCamPos     Save Length //Vertex Out.vpos = mul(pos,WorldView).xyz; //Pixel Out.ldepth = length(vpos.rgb);       FSTriangle VertexShader struct VS_OUT { float4 pos : SV_POSITION; float2 tex : TEXCOORD0; float4 vray : TEXCOORD1; }; //----------------------------------------------------------------------------- //SHADER VS_OUT VShader(uint ID : SV_VertexID) { VS_OUT Out; float4 p = float4(0,0,0,1); float2 t = float2(0,0); p.x = (float)(ID / 2) * 4 - 1; p.y = (float)(ID % 2) * 4 - 1; t.x = (float)(ID / 2) * 2; t.y = 1 - (float)(ID % 2) * 2; float4 v = float4(p.x, p.y, 1, 1); //ndc (at the back of cube) v = mul(v,InvViewProjection); v.xyz -= CamPosition.xyz; Out.pos = p; Out.tex = t; Out.vray= v; return Out; }   GBuffer part // Normalize the view ray, and apply the distance to reconstruct position float3 viewRay = normalize(vray); float viewDistance = Source2; //F32 Texture float3 positionWS = CamPosition + viewRay * viewDistance; Out.Position=positionWS But if i write the position and the reconstructed position to ColorTargets, they are not the same [sharedmedia=gallery:albums:1019]  
  10. From the album Reconstruct WorldPosition Problem

    This is a Quad with Center (0,0,0) ... Positions are written to Color
  11. From the album Reconstruct WorldPosition Problem

    This is the same Quad with Center (0,0,0) ... Positions are reconstructed and written to Color. The reconstruction is wrong

  14. Since i've lost my last slimdx source.. some time has passed. Now it's time to come back with a new project... I'm no professionel, but i will share my knowledge on my blog in future. Maybe sombody is interested. http://vbexengineblog.wordpress.com/ Here is my last Video of my Enviromental Camera. https://youtu.be/7NTkr5FkG2c   [sharedmedia=gallery:images:6946]   Have Fun & keep coding!
  15. So i have found the problem... in the SDK Shader the RasterizerState is set twice... That's not working right... and Culling is using the default Value technique10 RenderAlphaToCoverage { pass P0 { SetDepthStencilState( EnableDepthTestWrite, 0 ); SetRasterizerState( DisableCulling ); SetRasterizerState( EnableMultisampling ); SetBlendState( AlphaToCoverage, float4( 0.0f, 0.0f, 0.0f, 0.0f ), 0xFFFFFFFF ); SetVertexShader( CompileShader( vs_4_0, VsRenderScene() ) ); SetGeometryShader( NULL ); SetPixelShader( CompileShader( ps_4_0, PsAlphaToCoverage() ) ); } }
