GlutIdleFunc (staticCFunction ( ::onIdle ) ) GlutDisplayFunc (staticCFunction ( ::display ) ) Val title = 'The Amazing, Rotating Utah Teapot brought to you in OpenGL via freeglut.' GlutInitDisplayMode (GLUT _SINGLE or GLUT _RGB or GLUT _DEPTH ) GlutCreateWindow ( 'The Amazing, Rotating Utah Teapot brought to you in OpenGL via freeglut.' ) ДЄlthough there are a number of third party Go bindings for OpenGL, the following uses 'cgo' to interface directly with the C libraries. GlutInitDisplayMode (GLUT_SINGLE |GLUT_RGB |GLUT_DEPTH ) GlMaterialfv (GL_FRONT ,GL_SHININESS ,shini ) GlLightfv (GL_LIGHT0 ,GL_DIFFUSE ,white ) GlLightfv (GL_LIGHT0 ,GL_AMBIENT ,white ) GlMaterialfv (GL_FRONT ,GL_DIFFUSE ,matCol ) GlClear (GL_COLOR_BUFFER_BIT |GL_DEPTH_BUFFER_BIT ) This implementation sticks to the task requirements and only shows the teapot, it's rotating, so you can enjoy it's magnificence from all possible viewpoints and perspectives. freeglut did even better and implemented the rest of the tea set, yes, the API also provides a cup and a spoon. As well explained on the Wikipedia page ( link above ), the teapot played such an important role in the development of Computer Graphics, that Mark Kilgard honoured it by giving it it's own primitive drawing functions.
