(gl:eval-mesh-1 opengl mode p1 p2)


glMapGrid  and  glEvalMesh  are used in tandem to efficiently generate and evaluate a series of evenly-spacedmap domain values.  glEvalMesh steps through the integer domain of a  one-  or  two-dimensional  grid,  whoserange  is  the  domain  of  the  evaluation maps specified by glMap1 and glMap2.  mode determines whether theresulting vertices are connected as points, lines, or filled polygons.


           mode -- enumeration (int)

             p1 -- integer number

         opengl -- opengl instance

             p2 -- integer number

Returns: boolean
