This is very welcome indeed.  Massive kudos!

Thank you!

interesting, something i'm active around.

just checking, the only dependency for the compiled result is opengl?

OK, i see X server in there, unfortunately the target system i was currently looking at doesn't have x support, just egl.

[leonsal]

The dependencies on the X server are needed by the GLFW window manager (http://www.glfw.org).

We tried to abstract the window manager in the "window" package.

So it would be theoretically possible to build another window manager using

a Go binding for an EGL library and use it with the engine.

[simon place]

thanks for confirming that, i was guessing you had done that for x-platform support anyway.

i started making a 3d viewer myself with glfw last year, its as much shader as possible, not worked on it recently, apart from looking at non-x solutions.

[Jamey Cribbs]

Is there a proper place where we can ask questions?

For example, I am trying to figure out what the monitor resolution is before I create the window, as I have a very high resolution monitor that makes the example windows and text way too small.  I figure if I can determine if the monitor resolution is high, then I can have the program scale up the window size and all the text sizes.

I googled a bit and I saw some examples of using glfw to determine the monitor resolution, and I saw in the the source code of G3N that you are making calls to glfw, but I'm not sure if there is a clean way for me to ask for the monitor resolution using your library or is this something I should be doing outside of your library.

Sorry if this question is way too basic.  I have no experience at all with opengl so I'm just kind of finding my way.

Hi

This group is concerned with general aspects of the Go language.

Please generate an issue with your question in our repository: github.com/g3n/engine

We will try to answer.

Regards.
