This .obj viewer is based on the "smooth" program by Nate Robins found in the Kilgard GLUT package. The alpine sky box textures come from http://www.hazelwhorley.com/skyboxtex3_bitmaps.html The bunny.obj and buddha.obj models come from Stanford. The GreatLakesBiplaneHP.obj model comes from http://www.sharecg.com/v/25978/3D-Model/Great-Lakes-Biplane-Model The bobcat.obj model comes from http://www.sharecg.com/v/24771/3D-Model/Bobcat,3d-studio-and-wavefront-objects The .obj file reader code in glm.c isn't perfect. Not all .obj files are parsed correctly. There are often mistakes in material-to-triangle assignments. Mouse: Left = rotate Middle = scale Right = menu Keyboard: See pop-up menu for keyboard shortcuts, or press 'h'.
