OpenGL without X Windows

[bozzao]

Hi,
what do I have to do to make a OpenGL application that runs in the console? Without X Windows.

Thanks

You have to find some OpenGL implementation that can be run in the console. The only one that perhaps has hardware support is Mesa with Voodoo cards. I think that a more recent project without hw support exist but I do not know where to find it. The speed can not be compared with a "real" OpenGL implementation like nvidias but it will run in the console.

i think you have to use the frame buffer, this may be a good way.
hope someone else could give you more information.

There was a project a while back to port the dri to the frame buffer (using SDL on the frame buffer). Do a search for fbdri. The posts should be on opengl.org, I believe that they only got it working with the ati radeon's but they said that it should work with others with minimal effort.

I need a small and fast solution for 3D graphics. I have only 256mb of disk space (I am using a flash memory card) for the entire system. I am now using a celeron 900mhz. I can put about any video board I want.

Do you think that with this limitations I can run the X Windows with my open gl application with a hi performance? (it will be the only thing running in the machine so I don´t need anything else)

You may need some ram for X + you app, but it sounds like enough. You should get just fine performance with a good gfx card.

I have 256 of ram!

How much disk space does a full linux installation with X take?

My app have 100mb, more 32 of swap, leave me with 124mb of free disk space.

Well...what dp you mean a full instalation ?
It depends on the distribution..
X takes about 30 mb of space ( plus minus )
With linux + basic packages + lighweght interface ( like WM ) you should do it in 100 MB os HW.
And besides that...swap is optional..
If you'r going to use it only for development, nothign more you don't have to make a swap partition ( especialy if you have 256 RAM ).

You should look into one of the embedded linux distributions: hardhad, blue cat etc.

They easily fit in to less than you have.

But does they suport X Window and OpenGL?
