The basic interface to OpenGL, providing access to core ClassJavadoc GL * functionality up through the OpenGL 2.0 specification as well as ClassJavadoc GL * all vendor extensions.

ClassJavadoc GL * ClassJavadoc GL *

While the APIs for vendor extensions are unconditionally ClassJavadoc GL * exposed, the underlying functions may not be present. The method ClassJavadoc GL * {@link #isFunctionAvailable} should be used to query the ClassJavadoc GL * availability of any non-core function before it is used for the ClassJavadoc GL * first time; for example, ClassJavadoc GL * gl.isFunctionAvailable("glProgramStringARB"). On ClassJavadoc GL * certain platforms (Windows in particular), the most "core" ClassJavadoc GL * functionality is only OpenGL 1.1, so in theory any routines first ClassJavadoc GL * exposed in OpenGL 1.2, 1.3, and 1.4, 1.5, or 2.0 as well as vendor ClassJavadoc GL * extensions should all be queried. Calling an unavailable function ClassJavadoc GL * will cause a {@link GLException} to be raised.

ClassJavadoc GL * ClassJavadoc GL * {@link #isExtensionAvailable} may also be used to determine whether ClassJavadoc GL * a specific extension is available before calling the routines or ClassJavadoc GL * using the functionality it exposes: for example, ClassJavadoc GL * gl.isExtensionAvailable("GL_ARB_vertex_program");. ClassJavadoc GL * However, in this case it is up to the end user to know which ClassJavadoc GL * routines or functionality are associated with which OpenGL ClassJavadoc GL * extensions. It may also be used to test for the availability of a ClassJavadoc GL * particular version of OpenGL: for example, ClassJavadoc GL * gl.isExtensionAvailable("GL_VERSION_1_5");.
