Among them we can highlight:</p> + <ul> + <li><strong>GKS</strong> - Very complete 2D and 3D graphics library, but + with limited image resources. It is an ISO standard, and it implementations + are usually commercial. Tecgraf has an implementation of GKS which is no + longer used, being replaced by CD. <a href="http://www.bsi.org.uk/sc24/"> + http://www.bsi.org.uk/sc24/</a>.<br> + --------------------</li> + <li><strong>Mesa</strong> - 3D graphics library with support to the OpenGL + standard. Implemented in C. Aimed only at display, with attribute functions + for illumination and shading features. + <a href="http://www.mesa3d.org/" target="_blank">http://www.mesa3d.org/</a>.</li> + <li><strong>OpenGL</strong> - 3D graphics library with some 2D support. + Aimed only at display. A window CD canvas can coexist with an OpenGL canvas + at the same time. Note: When Double Buffer is used, do not forget to swap + buffer before redrawing with the CD library. <a href="http://www.opengl.org"> + http://www.opengl.org</a>.<br> + --------------------</li> + <li><strong>GGI</strong> - 2D graphics library aimed only at display. + <a href="http://www.ggi-project.org/">http://www.ggi-project.org/</a>.</li> + <li><strong>GD</strong> - Library only for drawing on images, saves PNG + files. Implemented in C. <a href="http://www.boutell.com/gd/"> + http://www.boutell.com/gd/</a>.</li> + <li><strong>GDK</strong> - Used by the GTK user interface toolkit. + Implemented in C. Aimed only at display, and contains several functions for + managing windows, keyboard and mouse. <a href="http://www.gtk.org/"> + http://www.gtk.org/</a>.</li> + <li><b>CAIRO</b> - A vector graphics library designed to provide + high-quality display and print output. Very interesting, lots of functions, + usually render in bitmaps on native systems. Display hardware acceleration is used + almost only to display the bitmaps. Although it can reach high quality + rendering. + <a href="http://cairographics.org/">http://cairographics.org/</a>.</li> + <li><strong>AGG</strong> - The AGG Project (Anti-Grain Geometry). High + Fidelity 2D Graphics A High Quality Rendering Engine for C++. Renders to a + bitmap then transfer it to the native system, just like Cairo. GNU GPL + license. <a href="http://www.antigrain.com/">http://www.antigrain.com/</a> </li> + </ul> + <p>Most of them are aimed only at one type of driver, usually display or + images, and sometimes user interface routines were also included. Others add + 3D drawing routines, as well as scene illumination routines. All this + unnecessarily increases their complexity and does not make them more complete + as 2D graphic libraries.</p> + <p>There are also several Graphics User Interface libraries that contain + drawing functions, like Qt and wxWidgets. </p> + <p>As to performance, CD is as good as any other, in some cases having a + better performance. Thus, the CD library offers unique features and quality as + a portable 2D graphic library.</p> + + +</body> + +</html> |
