      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.

vs 5_0 texture sampling

3 posts in this topic

I have a height map in my vertex shader that I use to move the vertex to right height. I use r32g32b32 texture. But when I create graphics device with debug flag I get the error below. Even though it shows me error everything works fine I mean I get the right height for the terrain. So do I need to change the format of my texture or is there a way to sample r32g32b32 textures on vertex shader?

D3D11 ERROR: ID3D11DeviceContext::DrawIndexed: The Shader Resource View in slot 1 of the Vertex Shader unit is using the Format (R32G32B32_FLOAT). This format does not support 'Sample', 'SampleLevel', 'SampleBias' or 'SampleGrad', at least one of which may being used on the Resource by the shader. The exception is if the corresponding Sampler object is configured for point filtering (in which case this error can be ignored). This also only applies if the shader actually uses the view (e.g. it is not skipped due to shader code branching). [ EXECUTION ERROR #371: DEVICE_DRAW_RESOURCE_FORMAT_SAMPLE_UNSUPPORTED]

This is calling itself an error but my reading of it is that it really should be just a warning.  Let's look at the message itself:

 

 

This format does not support 'Sample', 'SampleLevel', 'SampleBias' or 'SampleGrad', at least one of which may being used on the Resource by the shader. The exception is if the corresponding Sampler object is configured for point filtering (in which case this error can be ignored).

 

So, if you're using Load you're OK.  If you're using point sampling you're also OK.  I assume that with height mapping either or both are true (although filtering modes don't make sense with Load); in that case you can quite safely ignore it.

 

If it really bothers you, you could switch to using DXGI_FORMAT_R32G32B32A32_FLOAT which should suppress the message.  You may even be able to stash some extra needed data into that free alpha channel.
