<hr/><a name="details" id="details"></a><h2>Detailed Description</h2>
<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="a00035_source.html">glm/ext.hpp</a>&gt;. Otherwise, each extension needs to be included a specific file. </p>
</div>
<p>Handles the interaction between pointers and vector, matrix types. </p>
<p>This extension defines an overloaded function, glm::value_ptr, which takes any of the <a class="el" href="a00140.html">core template types</a>. It returns a pointer to the memory layout of the object. Matrix types store their values in column-major order.</p>
<p>This is useful for uploading data to matrices or copying data to buffer objects.</p>
<p>Example: </p>
<div class="fragment"><pre class="fragment"><span class="preprocessor"> #include &lt;<a class="code" href="a00034.html" title="OpenGL Mathematics (glm.g-truc.net)">glm/glm.hpp</a>&gt;</span>
<span class="preprocessor"> #include &lt;<a class="code" href="a00107.html" title="OpenGL Mathematics (glm.g-truc.net)">glm/gtc/type_ptr.hpp</a>&gt;</span>
<a class="code" href="a00138.html#ga8a44105c47072f9ea1413f15faa31f64" title="3 components vector of floating-point numbers.">glm::vec3</a> aVector(3);
<a class="code" href="a00138.html#gade0eb47c01f79384a6f38017ede17446" title="4 columns of 4 components matrix of floating-point numbers.">glm::mat4</a> someMatrix(1.0);
glUniform3fv(uniformLoc, 1, glm::value_ptr(aVector));
glUniformMatrix4fv(uniformMatrixLoc, 1, GL_FALSE, glm::value_ptr(someMatrix));
</pre></div><p>&lt;<a class="el" href="a00107.html" title="OpenGL Mathematics (glm.g-truc.net)">glm/gtc/type_ptr.hpp</a>&gt; need to be included to use these functionalities. </p>
