glColor Problem

[suresh kannan]

Hi I am displaying text using Outline fonts.
As per OpenGL documentation the glColor() and glCallLists() calls should be within glBegin() and glEnd(). What should be the mode for glBegin(...)?.

glBegin(?);
glColor4f(Red,Green,Blue,Alpha);
glCallLists(strlen(string),GL_UNSIGNED_BYTE, string);
glEnd();

Thanks,

You actually do not need to use glBegin in this case. The glBegin/glEnd commands are compiled in the display list when you call wglUseFontOutlines.

So, the only thing you have to do is:




glColor4f(Red,Green,Blue,Alpha);
glCallLists(strlen(string),GL_UNSIGNED_BYTE, string);


Regards.

P.S.: actually, if you add glBegin/glEnd around these calls, chances are that nothing will appear (you are not allowed to use glBegin between glBegin/glEnd !).
