This library shows a bug in the 'jumps' window of the IDE.

When a return type is defined in the function name "FUNCTION vector_add AS Tvector:" the jump window shows the function name as "Tvector"... so in the case of this library there are six jumps all called "Tvector"... the actual jump works fine though.

Excellent, thank you Gernot.

..\..\..\GeFr\Fun\DINGS\Samples\Common\qmath.gbas is missing, cant compile?

Could some kind soul add German language comments plz?

OK, that seemed to fix the compile... do I need to call the new function to initialise the Global Gernot?

OK, heres the code... this is a library, not a standalone program...

Just had a wee play with this... this is incredibly powerful for adding your own OpenGL features that GLBasic does not natively support...!

Nice.

Ah, I see. OK, not a biggie then, thank you Gernot.

Ah thank you, so any up to date OpenGL API Header will do?

This URL... "http://www.css.taylor.edu/~btoll/resources/graphics/opengl/xp/gl.h" is no longer available.

Excellent! I'll give the Inline call a go...

And question one?
