@brief Compile-time information about OpenGL extensions
|
|
|
|
|
|
|
|
|
|
Each extension is `struct` named hierarchically by prefix, vendor and
|
|
|
|
|
extension name, for example `GL::APPLE::vertex_array_object`. Each struct has
|
|
|
|
|
the same public methods as Extension class (requiredVersion(), coreVersion()
|
|
|
|
|
and string(), but these structs are better suited for compile-time decisions
|
|
|
|
|
rather than %Extension instances. See Context::isExtensionSupported() for
|
|
|
|
|
example usage.
|
|
|
|
|
|
|
|
|
|
This namespace is built by default. To use it, you need to add `${MAGNUM_INCLUDE_DIRS}`
|
|
|
|
|
to include path and link to `${MAGNUM_LIBRARIES}`. See @ref building and
|
|
|
|
|
@ref cmake for more information.
|
|
|
|
|
@see MAGNUM_ASSERT_EXTENSION_SUPPORTED()
|
|
|
|
|
@todo Manual indices for extensions, this has gaps
