What Exactly is OpenGL?

BlitzMax Forums/BlitzMax OpenGL Programming/What Exactly is OpenGL?

Some stuff is quicker than other Blitz's, but when drawing and most especially; manipulating special effects - above 256x256 and this is with using writepixel- it's increasingly slow as previously with the other flavours of Blitz. And I have a Geforce4 MX graphics card, Pentium4 2.5 Ghz processor and 512 MB Ram. So theretically, it should be running at comfortable FPS speeds. 24FPS at 640x480 is alittle bit of a rubbish score for drawing.

And the main reason for asking about OpenGL, is there is alot of confusion on what it's for - as there's alot of 3D only examples. Seeming as BMAX uses OpenGL as it's core, then it would be excellent to see more 2D examples / tutorials and information on it included in the reference manuals etc. As the details of what commands do (all round) is not very clear at all.

Does anyone know if there's any difference in speed to the inbuilt readymade commands like Plot x,y, writepixel, to using direct OpenGL commands? Also BR any chance of the GL extensions to have a unique colour.

Thanks
