copied!<p>To match your question and to draw a cube in OpenGL (compatibility profile) you can use this code:</p> <pre><code> void drawCube(float x, float y, float z) { glBegin(GL_QUADS); glVertex3f(-1.0f+x, -1.0f+y, -1.0f+z); glVertex3f(1.0f+x, -1.0f+y, -1.0f+z); glVertex3f(1.0f+x, 1.0f+y, -1.0f+z); glVertex3f(-1.0f+x, 1.0f+y, -1.0f+z); glVertex3f(-1.0f+x, -1.0f+y, -1.0f+z); glVertex3f(-1.0f+x, -1.0f+y, 1.0f+z); glVertex3f(-1.0f+x, 1.0f+y, -1.0f+z); glVertex3f(-1.0f+x, 1.0f+y, 1.0f+z); glVertex3f(-1.0f+x, -1.0f+y, -1.0f+z); glVertex3f(-1.0f+x, -1.0f+y, 1.0f+z); glVertex3f(1.0f+x, -1.0f+y, 1.0f+z); glVertex3f(1.0f+x, -1.0f+y, -1.0f+z); glVertex3f(-1.0f+x, -1.0f+y, 1.0f+z); glVertex3f(1.0f+x, -1.0f+y, 1.0f+z); glVertex3f(1.0f+x, 1.0f+y, 1.0f+z); glVertex3f(-1.0f+x, 1.0f+y, 1.0f+z); glVertex3f(-1.0f+x, -1.0f+y, 1.0f+z); glVertex3f(1.0f+x, -1.0f+y, 1.0f+z); glVertex3f(1.0f+x, 1.0f+y, 1.0f+z); glVertex3f(-1.0f+x, 1.0f+y, 1.0f+z); glVertex3f(-1.0f+x, 1.0f+y, -1.0f+z); glVertex3f(-1.0f+x, 1.0f+y, 1.0f+z); glVertex3f(1.0f+x, 1.0f+y, 1.0f+z); glVertex3f(1.0f+x, 1.0f+y, -1.0f+z); glEnd(); } </code></pre> <p><strong>I do not recommend this function</strong>, use instead the <a href="http://www.opengl.org/sdk/docs/man/xhtml/glTranslate.xml" rel="nofollow"><code>glTranslatef(x, y, z)</code></a> solution discribed in another answer. Like this function:</p> <pre><code> void drawCube(float x, float y, float z) { glPushMatrix(); glTranslatef(x, y, z); glBegin(GL_QUADS); glVertex3f(-1.0f,-1.0f ,-1.0f); glVertex3f(1.0f, -1.0f, -1.0f); glVertex3f(1.0f, 1.0f, -1.0f); glVertex3f(-1.0f, 1.0f, -1.0f); glVertex3f(-1.0f, -1.0f, -1.0f); glVertex3f(-1.0f, -1.0f, 1.0f); glVertex3f(-1.0f, 1.0f, -1.0f); glVertex3f(-1.0f, 1.0f, 1.0f); glVertex3f(-1.0f, -1.0f, -1.0f); glVertex3f(-1.0f, -1.0f, 1.0f); glVertex3f(1.0f, -1.0f, 1.0f); glVertex3f(1.0f, -1.0f, -1.0f); glVertex3f(-1.0f, -1.0f, 1.0f); glVertex3f(1.0f, -1.0f, 1.0f); glVertex3f(1.0f, 1.0f, 1.0f); glVertex3f(-1.0f, 1.0f, 1.0f); glVertex3f(-1.0f,-1.0f ,1.0f ); glVertex3f(1.0f, -1.0f, 1.0f); glVertex3f(1.0f, 1.0f, 1.0f); glVertex3f(-1.0f, 1.0f, 1.0f); glVertex3f(-1.0f, 1.0f, -1.0f); glVertex3f(-1.0f, 1.0f, 1.0f); glVertex3f(1.0f, 1.0f, 1.0f); glVertex3f(1.0f, 1.0f, -1.0f); glEnd(); glPopMatrix(); } </code></pre> <p>This function is far from being perfect, but it should suffice. Happy coding!</p>
