Comparing CD with Other Graphics Libraries

+ +

There are other graphics libraries, with some portability among operational + systems, available on the Internet. Among them we can highlight:

GKS - 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. + http://www.bsi.org.uk/sc24/.
+ --------------------
Mesa - 3D graphics library with support to the OpenGL + standard. Implemented in C. Aimed only at display, with attribute functions + for illumination and shading features. + http://www.mesa3d.org/.
OpenGL - 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. + http://www.opengl.org.
+ --------------------
GGI - 2D graphics library aimed only at display. + http://www.ggi-project.org/.
GD - Library only for drawing on images, saves PNG + files. Implemented in C. + http://www.boutell.com/gd/.
GDK - Used by the GTK user interface toolkit. + Implemented in C. Aimed only at display, and contains several functions for + managing windows, keyboard and mouse. + http://www.gtk.org/.
CAIRO - 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. + http://cairographics.org/.
AGG - 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. http://www.antigrain.com/

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.

There are also several Graphics User Interface libraries that contain + drawing functions, like Qt and wxWidgets.

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.
