WebGL for node.js

[Brian McKenna]

Hi everyone,

I've started a WebGL implementation using node.js, SDL and DevIL. It's
on GitHub here:

http://github.com/pufuwozu/node-webgl

I'm planning on creating some cool projects using WebGL in the future
and I thought it would be great if I could use the same code on the
desktop. I'm excited to hear what people think of the project.

Thanks,
Brian McKenna

Whats the difference between opengl and webgl?

node-ogl provides you direct api access to opengl, where as webgl is a subset / wrapper for opengl (mostly for use in a dom + browser).

I think this is interesting, It might be worth splitting out SDL into another project as it provides a much larger subset of functionality than what is needed for getting an ogl context.

I'd like to chat with you about using node-ogl as well.. I think with the majority of the API wrapped already, writing a webgl wrapper on top of it *might* make things easier.  I'd like to hear your opinions on this.

And for fun, last weekend I landed texture mapping (http://github.com/tmpvar/node-ogl/raw/master/example/nehe/lesson6.png) and other functions that take pointers as arguments.

I started working on this project very slowly about a month ago. At
the time I searched around for node.js OpenGL bindings but it looks
like they weren't around then. It's a shame that I duplicated some of
that effort.

I'll get in contact sometime soon. I'm really interested in building
on top of node-ogl - thanks for the good work! I just need to come up
with a way to build on top of it nicely.

I'm about to add node-ogl to http://wiki.github.com/ry/node/modules -
hope you don't mind.

Thanks,
Brian McKenna

Not node specific, OpenGL 2.1+ (w/some Glut, Glu, and ES) for v8
(http://github.com/philogb/v8-gl).

Agreed, I'm still trying to get various platform independent windowing libraries to work. so far I've had minimal luck. the linux version (only one currently working) is using a stupid simple wrapper around glfw's window creation.  Unfortunately I haven't been able to get it working under osx, but I'm continuing to battle with it nightly.

 

The problem with these libraries is they try to be the end all, by providing input/sound/image loading/video/etc.  I simply want a window + window events + opengl context.  In all reality, I may end up coding this up myself.

Nope, I wanted to have a bit more done before really announcing this, but I really don't mind either way (it's at a pretty decent point right now.. on linux).

When I saw this, It looked like it was no longer being actively developed or maintained.  I can't remember where I saw that, but looking at it now perhaps it will aid in solving some of my cross platform issues (I'd like to use glut as it removes a dependency from node-ogl)

I have a fork of that that I started working on adding audio support. When I get some more time I'll finish it off and start working on some other cool stuff like networking. I'm hoping to eventually make it a competitive alternative to pygame. :)

Very cool!  If I can offer my opinion, I think all of these libraries should be kept as separate as possible.  For instance, I would hate to have to setup a window if all I want to do is play a sound or track movement of a mouse/joystick.

my 2 cents

It's still works fine, albeit a little iffy on the compiling side, since V8 has changed somewhat since the last release. My fork of it pulls the specific revision of V8 that it needs, so mine might be a little easier to compile. If you have any issues compiling either, I can help you out. It was a pain for me, since the support for non-mac systems was a bit incomplete--I had to add some of my own stuff to make it work on my linux system.

[Stephen Belanger]

That's the eventual plan. I want to organize it in such a way that when you compile it you can select to exclude features. IE: --disable-sdl --disable-openal --disable-alut --disable-networking

Each library gets it's own global object, so at the moment there is GL, Glu, Glut and Al. It'd actually be pretty easy to just make a few changes to the makefile to make it compile without a specific part of that at the moment.

Oh, and you shouldn't actually need to setup a window presently, but there is no looping mechanism aside from the one built into OpenGL, so it would just start, run the script once and end as it is now.

This is pretty cool i think. Similar use (and more useful, really) to what I
made here: http://code.google.com/p/wtfgame/

OpenGL is a standard programming toolkit written in C that allows
programs to write code that utilizes the GPU particularly for 3D
graphics.
WebGL exposes OpenGL to web programmers though a javascript wrapper. A
nodeJS implementation would expose openGL for node applications. but
you could have googled that

WebGL is OpenGL ES, not OpenGL. There aren't many differences, but enough that we should avoid misleading readers that aren't in the know about that stuff. ;)
