      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.

hello ,

what are your recommended math books for computer vision course (3D and 2D) , I need books names ?
and what are your recommended geometry books for that course too ?

thanks :).

The phrase "computer vision" much like "artificial intelligence" is not a well defined term and tends to me different things to different people.

 

Could you be more specific about what you want to learn about?

@jwezorek,

I need books for computer vision related to 3D associated with math books for it smile.png .However , I don't know if there is field in computer vision related to 3D games????

by the way, I don't want computer vision books for 
robot or digital camera no but for 3D (3D computer graphics ) of course smile.png.

I don't know much about this field !! so I don't know if my question is right ! 

 

I just know about computer graphics and digital image processing.
I took as prerequisites math books ( Calculas 1  & 2 , linear algebra , discrete math ).

"Computer Vision" usually means making the computer understand and interpret signals, from for example cameras or images (typically to build an awareness or internal model of its content) so I don't really understand what you mean with computer vision for 3D and games...

Do you mean visualisation? That is, how to generate an image from your 2D or 3D data? Rendering, Raytracing, things like that? Edited by Olof Hedman

mrmohadnan I agree with what Olof says above. I'm not sure what you mean by computer vision applied to 3D games. Could you tell us more about what you want to do? and we'll try to tell you what to research. Edited by jwezorek

I think as an introduction '3D Math Primer for Graphics and Game Development' might suit.

Well, yeah, that's about 3D math and graphics but the the OP was asking about computer vision.

I'm not sure what the OP means. The only thing I can think of is that "computer graphics" is basically about doing 3D model -> 2D raster image. Maybe mrmohadnan wants to go 2D raster image -> 3D model -- that is "computer vision" and is sort of related to 3D games, but without more info not sure. Edited by jwezorek

@Olof Hedman , jwezorek , eppo ,

thanks , 

so you say visualisation (rendering , ray...etc) are different from Computer Vision field  , and they don't relate?

Q1 : Okay 
Olof as you say , I have to take signal processing course and random theory as prerequisites for Computer vision right?

jwezorek , 

I wanna to take data from Camera and capture objects with accosiated with it's cloth ( Material ) and import them into 3D max and export it as Model ready for game engine without needs to make materials in 3d application smile.png (the problem I don't know anything about signal processing !!!!! because Olof says  ,"understand and interpret signals " :(

 

 


Q2 : So thats why I am asking , is there a field in computer vision close to Visualization (Rendering , tracing ...etc) or not ?

I don't know ... but I'm afraid extracting 3D models and material information from a 2D image in a completely unsupervised manner is beyond the state of the art of computer vision today. Unless I'm misunderstanding...

Actually, you can do it, if you have several images of the object from different angles.

But it's a very advanced subject, and you will not get models you can use directly in a game.

 

One low cost solution for a simple "3D scanner" is to use one (or two for better accuracy) kinects. 

The API is open, and you get 2 images, one normal camera image, and one depth image, with the distance from the kinect to each point in the camera image.

I'm pretty sure you can find some software to do it out there, at least there are for motion capture.

But any model extracted from it would also be very noisy and need extensive cleanup to be usable in a game.

 

But it seems it is computer vision you want, after all.

I don't have any tips for any books unfortunately...

jwezorek

you are right :) that's what I want from "2D -> 3D" 

I used google and found that Computer vision in general the mathmematics requirements are :
geometry ( any recommended books ?)
Optimiazation ( what you prefer for Optimization : " linear programming " , "complex analysis ")
statistics ( I think introduction to probability course is good !)
and about physics prerequisities books for computer vision :
I think that digital signal processing is enough !
