If -<tt>glewInit()</tt> returns <tt>GLEW_OK</tt>, the initialization -succeeded and you can use the available extensions as well as core -OpenGL functionality. For example: -</p> - -<p class="pre"> -#include <GL/glew.h><br> -#include <GL/glut.h><br> -...<br> -glutInit(&argc, argv);<br> -glutCreateWindow("GLEW Test");<br> -GLenum err = glewInit();<br> -if (GLEW_OK != err)<br> -{<br> - /* Problem: glewInit failed, something is seriously wrong. */<br> - fprintf(stderr, "Error: %s\n", glewGetErrorString(err));<br> - ...<br> -}<br> -fprintf(stdout, "Status: Using GLEW %s\n", glewGetString(GLEW_VERSION));<br> -</p> - -<h2>Checking for Extensions</h2> - -<p> -Starting from GLEW 1.1.0, you can find out if a particular extension -is available on your platform by querying globally defined variables -of the form <tt>GLEW_{extension_name}</tt>: -</p> - -<p class="pre"> -if (GLEW_ARB_vertex_program)<br> -{<br> - /* It is safe to use the ARB_vertex_program extension here. */<br> - glGenProgramsARB(...);<br> -}<br> -</p> - -<p> -<b>In GLEW 1.0.x, a global structure was used for this task. To ensure -binary compatibility between releases, the struct was replaced with a -set of variables.</b> -</p> - -<p> -You can also check for core OpenGL functionality. For example, to -see if OpenGL 1.3 is supported, do the following: -</p> - -<p class="pre"> -if (GLEW_VERSION_1_3)<br> -{<br> - /* Yay! OpenGL 1.3 is supported! */<br> -}<br> -</p> - -<p> -In general, you can check if <tt>GLEW_{extension_name}</tt> or -<tt>GLEW_VERSION_{version}</tt> is true or false. -</p> - -<p> -It is also possible to perform extension checks from string -input. Starting from the 1.3.0 release, use <tt>glewIsSupported</tt> -to check if the required core or extension functionality is -available: -</p> - -<p class="pre"> -if (glewIsSupported("GL_VERSION_1_4 GL_ARB_point_sprite"))<br> -{<br> - /* Great, we have OpenGL 1.4 + point sprites. */<br> -}<br> -</p> - -<p> -For extensions only, <tt>glewGetExtension</tt> provides a slower alternative -(GLEW 1.0.x-1.2.x). <b>Note that in the 1.3.0 release </b> -<tt>glewGetExtension</tt> <b>was replaced with </b> -<tt>glewIsSupported</tt>. -</p> - -<p class="pre"> -if (glewGetExtension("GL_ARB_fragment_program"))<br> -{<br> - /* Looks like ARB_fragment_program is supported. */<br> -}<br> -</p> - -<h2>Experimental Drivers</h2> - -<p> -GLEW obtains information on the supported extensions from the graphics -driver. Experimental or pre-release drivers, however, might not -report every available extension through the standard mechanism, in -which case GLEW will report it unsupported. To circumvent this -situation, the <tt>glewExperimental</tt> global switch can be turned -on by setting it to <tt>GL_TRUE</tt> before calling -<tt>glewInit()</tt>, which ensures that all extensions with valid -entry points will be exposed. -</p> - -<h2>Platform Specific Extensions</h2> - -<p> -Platform specific extensions are separated into two header files: -<tt>wglew.h</tt> and <tt>glxew.h</tt>, which define the available -<tt>WGL</tt> and <tt>GLX</tt> extensions. To determine if a certain -extension is supported, query <tt>WGLEW_{extension name}</tt> or -<tt>GLXEW_{extension_name}</tt>. For example: -</p> - -<p class="pre"> -#include <GL/wglew.h><br> -<br> -if (WGLEW_ARB_pbuffer)<br> -{<br> - /* OK, we can use pbuffers. */<br> -}<br> -else<br> -{<br> - /* Sorry, pbuffers will not work on this platform. */<br> -}<br> -</p> - -<p> -Alternatively, use <tt>wglewIsSupported</tt> or -<tt>glxewIsSupported</tt> to check for extensions from a string: -</p> - -<p class="pre"> -if (wglewIsSupported("WGL_ARB_pbuffer"))<br> -{<br> - /* OK, we can use pbuffers. */<br> -}<br> -</p> - -<h2>Utilities</h2> - -<p> -GLEW provides two command-line utilities: one for creating a list of -available extensions and visuals; and another for verifying extension -entry points. -</p> - -<h3>visualinfo: extensions and visuals</h3> - -<p> -<tt>visualinfo</tt> is an extended version of <tt>glxinfo</tt>. The -Windows version creates a file called <tt>visualinfo.txt</tt>, which -contains a list of available OpenGL, WGL, and GLU extensions as well -as a table of visuals aka. pixel formats. Pbuffer and MRT capable -visuals are also included. For additional usage information, type -<tt>visualinfo -h</tt>. -</p> - -<h3>glewinfo: extension verification utility</h3> - -<p> -<tt>glewinfo</tt> allows you to verify the entry points for the -extensions supported on your platform. The Windows version -reports the results to a text file called <tt>glewinfo.txt</tt>. The -Unix version prints the results to <tt>stdout</tt>. -</p> - -<p>Windows usage:</p> - <blockquote><pre>glewinfo [-pf <id>]</pre></blockquote> - -<p>where <tt><id></tt> is the pixel format id for which the -capabilities are displayed.</p> - -<p>Unix usage:</p> -<blockquote><pre>glewinfo [-display <dpy>] [-visual <id>]</pre></blockquote> - -<p>where <tt><dpy></tt> is the X11 display and <tt><id></tt> is -the visual id for which the capabilities are displayed.</p> - -<!-- begin footer.html --> -</td></tr></table></body> -<!-- end footer.html --> - |
