Function:cs2socb
From S2PLOT
cs2socb
Register function that will draw direct OpenGL graphics when called.
Prototype
void cs2socb(void *oglfn);
Description
Register function that will draw direct OpenGL graphics when called. This is a highly advanced capability of s2plot that is open to many potential pitfalls. Only experienced OpenGL programmers should attempt to use it! Use NULL argument to disable this callback. The coordinate system for drawing geometry in this function is the viewport one. The OpenGL callback must be of the form:
void oglfn(void).
