<p>Functions and types that the GLSL specification doesn't define, but useful to have for a C++ program. </p>
<p>GTC extensions aim to be stable.</p>
<p>Even if it's highly unrecommended, it's possible to include all the extensions at once by including &lt;<a class="el" href="a00024.html" title="GLM Core (Dependence) ">glm/ext.hpp</a>&gt;. Otherwise, each extension needs to be included a specific file. </p>
