I removed the call and the output file is a valid PGM file. C, we obtain a checkerboard pattern where the black faces are par-allelograms and the white faces are arbitrary (non-planar) polygons. For examaple, Given a character (C), a length (L), a width (W), and a size (N), write a C++ program to draw a board of size (2N x 2N) consisting of cells filled up with character C, length of L, and width of W. The board cells have to be painted like a chess board, Assume C = ‘&’, L = 4, W = 6, and N = 3, The output would be this (without the border lines). We therefore use a control mesh to generate seamless checkerboard patterns of arbitrary topology. site design / logo © 2021 Stack Exchange Inc; user contributions licensed under cc by-sa.
