+/// @brief Handles the interaction between pointers and vector, matrix types.
+/// 
+/// This extension defines an overloaded function, glm::value_ptr, which
+/// takes any of the \ref core_template "core template types". It returns
+/// a pointer to the memory layout of the object. Matrix types store their values
+/// in column-major order.
+/// 
+/// This is useful for uploading data to matrices or copying data to buffer objects.
+///
+/// Example:
+/// @code
+/// #include <glm/glm.hpp>
+/// #include <glm/gtc/type_ptr.hpp>
+/// 
+/// glm::vec3 aVector(3);
+/// glm::mat4 someMatrix(1.0);
+/// 
+/// glUniform3fv(uniformLoc, 1, glm::value_ptr(aVector));
+/// glUniformMatrix4fv(uniformMatrixLoc, 1, GL_FALSE, glm::value_ptr(someMatrix));
+/// @endcode
+/// 
+/// <glm/gtc/type_ptr.hpp> need to be included to use these functionalities.
