|
|
<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="a00142.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>
