Hey,
I want to ani-alias a scene, but the only things I am using now is the glEnable(GL_POINT_SMOOTH etc. all these functions. Now I read that OpenGL was planning to remove this way of anti-aliasing, and that some new driver will stop supporting this method. And because of some other reasons, I want to use multi-sampling as a way to perfomr this action. Could anyone explain this method to me? I read some tutorials, but I couldn't comprehend the whole story.

What does multisampling and point smoothing have to do with accumulation buffers?
I don't know either but if you want full scene anti-aliasing, then you need to chose a pixelformat that supports full scene anti-aliasing. This is something that is OS specific.
Here is the Windows version

an open source GLU replacement library. Much more modern than GLU.
float matrix[16], inverse_matrix[16];
glhLoadIdentityf2(matrix);
glhTranslatef2(matrix, 0.0, 0.0, 5.0);
glhRotateAboutXf2(matrix, angleInRadians);
glhScalef2(matrix, 1.0, 1.0, -1.0);
glhQuickInvertMatrixf2(matrix, inverse_matrix);
glUniformMatrix4fv(uniformLocation1, 1, FALSE, matrix);
glUniformMatrix4fv(uniformLocation2, 1, FALSE, inverse_matrix);
ok, seems quite complex....
maybe you can give some tips or sth before I try this out? So maybe you know how to find the suitable pixelformat easily?

The title of this post is "OpenGL accumulation buffer". Multisampling has nothing to do with accumulation buffers, and neither does point smoothing.well, what i said is that I used this pointsmooth system to anti-alias now. But i heard that there is a technique called 'multisampling" or sth. So i wanted to know how you perfomr this and do this.
I thought you needed the accumulation buffer for multisampling??? So it's not??
oh terrible mistake..
