Hopefully, it shouldcompile and run on any platform with gcc/g++ and OpenGL or IrisGL.For the OpenGL version, it is also necessary to have Mark Kilgard'sOpenGL Utility Toolkit (GLUT) installed. This toolkit is freelyavailable on the WWW	http://www.sgi.com/Technology/openGL/glut.htmlor via anonymous ftp from	sgigate.sgi.com:/pub/opengl/xjournal/GLUT/You will also need to edit the makefile and assign the variablesGLUTINC and GLUTLIB values appropriate for your platform.
