how to enable GL_LINE_SMOOTH
Author
hi,
i have drawn a few QUADS with texture and
would like to enable the LINE_SMOOTH.
I added the following 2 lines to my code:
Gl.glEnable (Gl.GL_LINE_SMOOTH);
Gl.glHint (Gl.GL_LINE_SMOOTH_HINT, Gl.GL_NICEST);
is this sufficient to enable the anti aliasing?
because nothing is happening.
any tips what i am doing wrong?
thanx
Hello,at your Initialization function add the following lines.
glEnable(GL_LINE_SMOOTH);
glEnable(GL_BLEND);
glBlendFunc(GL_SRC_ALPHA,GL_ONE_MINUS_SRC_ALPHA); glHint(GL_LINE_SMOOTH_HINT,GL_NICEST);
glEnable(GL_LINE_SMOOTH);
glEnable(GL_BLEND);
glBlendFunc(GL_SRC_ALPHA,GL_ONE_MINUS_SRC_ALPHA); glHint(GL_LINE_SMOOTH_HINT,GL_NICEST);
Did you forget to disable texturing before drawing the lines? And what's the behaviour you get? "Nothing is happening" could mean a lot of things, like are the lines showing up at all, or are they just not anti-aliased?

they are not antialiased.
i enabled the antialiasing code as
suggested above. then started to
do some drawing.
some not textured triangels and
some textured Quads, none of them
seemed to be antialiased.

Quote:Original post by sitwindGL_LINE_SMOOTH is meant for antialiasing lines... GL_POLYGON_SMOOTH is for polygons. Depending on what you're doing, you're probably better off with multisampling if it's available.
