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.

pixelbuffer? frame? how to call it

3 posts in this topic

I got a table of unsigneds, here i render things per pixel,

The trouble is if I dad to use it for years I should chose a real

good name for this table, and cannot really decide what name

would be good, I used many: pBits, pixels, pixelbuffer think also about 

frame, target, dont know seen some use real much names for this

 

What name to choose? I thing this better should be shorter than longer 

but also should be good (also need names for its sizes like int pixels_x,

int pixels_y)

 

?

 

some advice?

Not so short, but maybe framebuffer?

 

That is a pretty common name for a buffer you draw into

 

I also thinked so, but is such pixelbuffer i mean, a

framebuffer? (does not framebuffer have some other

meaning realted to gpu or something?)

 

also it is somewhat to long, also this 'buffer' is vague 

more plastic would be for example framebitmap,

rawframebits or something

 

as to frame and as to bitmap 

 

this is bitmap but this is not general bitmap but frame

contents (not sure if i can or shuld redesign my framework to 

render to any bitmap then only blit it so framebuffor notion would 

be skipped at all

 

as to frame it has other strong meaning so also im not sure if i could use this (maybe?)

 

recently i was using pixelbuffer name but i am unhappy with it

 

(if someone has some idea better or worse feel free to advice that)

I wouldn't waste too many cycles over-thinking it.

 

'buffer' is common for refering to a homogeneous block of memory -- if we're talking about an internal name (e.g. a class member variable) then something like that is appropriate. I also sometimes will choose a simple descriptor of what the data is in plural form, like "pixels".

 

If we're talking about a higher-level concept -- for example, a class your app exposes which represents the backing storage for draw operations -- then something like 'framebuffer' that describes it more conceptually is appropriate. In my old software rendering library I originally had Textures (image data sources), and Surfaces (derived from Texture, adding methods to support draw calls), but I realized not long later that the distinction was pretty silly, and the making a single class that was const-correct could serve as both mutable and non-mutable image storage. I also separated the drawing methods from the storage itself.

 

Its been awhile since I looked, but I believe the current state of affairs is that I have 'Surface's that are mutable or imitable depending on whether they are declared const -- those that are const can't be the target of drawing operations, and are loaded with image data through a callback provided at construction, those that are not const can be the target of draw operations or a source of image data.
