[LinuxSSN-devel] Re: OpenGL Branch

[Joe V. <jo...@ve...>]

Ah, you should take a look at my font.cpp file in the ssn3d bundle I sent you... I switch to ortho mode to draw the text... gluOrtho2d is just calling glOrtho with near and far set to -1 and 1, respectively, which isn't really much of a reason to use it instead of glOrtho (just pass -1 and 1 into it!) because glut sometimes isn't distributed along with OpenGL (like with windows) and since we're already using SDL for our window creating and event handling, there's no real reason to add GLUT.  That's my two cents anyway....

Well, I'm probably the least familiar with the code as it currently is, but perhaps you could modify the main.cpp to use OpenGL, and then we could just take it from there... I might make a class to make the loading and display of 2D graphics a bit easier, for example.  Or I could probably convert over one of the other stations... or I could work on implementing some aspect of the code I've got in that ssn3d bundle.
