JSFBGL :: JavaScript FrameBuffer Graphic Library

[benny]

Hi all,

today I released JSFBGL :: Javascript Framebuffer Graphic Library !

It is a little experimental art project to provide a graphic library similar to
TinyPTC e.g. in JavaScript. Do not take it too seriously

Project Site: http://www.weltenkonstrukteur.de/?site=works&prd=jsfbgl

Three examples are available online (see project site):



Any feedback welcome.

Really nice, but your library seems to be a little slow.

Thanks. And you are right. This lib is definately slow - or what I wrote on my
page .... rather cpu-consuming. But this is just an experimental approach
to simulate a framebuffer in javascript without having a fast memory copy
possibility to assign a frame buffer to the actual drawing buffer. So keep the
'table' (buffer) as small as possble.

This looks like a nice engine. However I think this engine focuses more on
moving dhtml layers around than on manipulating certain 'pixels'. I do not
want
to depreciate that engine but it seems to be a different approach. Anyway,
thanks for posting that link


@DD: thx !


@traumatic: long time no see. how's life ? <crypt>heard from rings that

Added a new fx. Pixelfade - pixelwise fading between two pictures.

Added: a little commandline tool (written in pb) that converts any bitmap
file into a javascript array source code for using it with jsfbgl.

Download link remains the same (see jsfbgl_bin/ folder):

How to use it? This generate a file?

Yup. It just simply puts out an array containing the html-colors as a java-
script source. This can be used in this library. So far, the library doesnt
support a buildt in loadImage function - so you have to do it by your-
self atm.

I enclosed the Pixelfade example in this package so you can see how
it works ( http://www.weltenkonstrukteur.de/dl/jsfbgl.zip )

The converter usage is like this :

Code: Select all

bmp2jraw.exe src.bmp dst.jraw array_name

coded a little snake game today using jsfbgl. Resolution is a 20 cell * 20 cell large html-
table. Each table 6*6pixel big. Well, just to prove that even simple games are possible to
be played in a html-table
