Hi ,
   Which of the following will be faster or better when i want to
rotate the following polygons

1. I use the following operation for n-number of times and put them in
Gl Display List and then perform rotations depending on user input .

       GlPushMatrix;
       glMultMatrixf(...);
     // more than 500  , 3 sided convex polygons
       GlPopMatrix

2. I post multipy the 3 - points of all the polygon with the matrix and
put them in Gl Display List and then perform rotations depending on
user input .

Thanking you
