## Detailed Description

Handles the interaction between pointers and vector, matrix types.

This extension defines an overloaded function, glm::value_ptr, which takes any of the 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:

#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));

<glm/gtc/type_ptr.hpp> need to be included to use these functionalities.
