<strong>OpenGL</strong> Geometric Primitives • All geometric primitives are specified by vertices GL_POINTS GL_LINES GL_LINE_STRIP GL_POLYGON GL_LINE_LOOP GL_TRIANGLES GL_QUAD_STRIP GL_TRIANGLE_STRIP GL_TRIANGLE_FAN GL_QUADS
Specifying Geometric Primitives • Primitives are specified using glBegin( primType ); glEnd(); • primType determines how vertices are combined glBegin( primType ); for ( i = 0; i < n; ++i ) { glColor3f( red[i], green[i], blue[i] ); glVertex3fv( coords[i] ); } glEnd();
