### <a name="section3_7"></a> 3.7. Disabling default constructor initialization
By default and following GLSL specifications, vector and matrix default constructors initialize the components to zero. This is a reliable behavior but initialization has a cost and it’s not always necessary.
This behavior can be disable at compilation time by define GLM\_FORCE\_NO\_CTOR\_INIT before any inclusion of &lt;glm/glm.hpp&gt; or other GLM include.

Some Windows headers define min and max as macros which may cause compatibility with third party libraries such as GLM.
It is highly recommanded to [define NOMINMAX](http://stackoverflow.com/questions/4913922/possible-problems-with-nominmax-on-visual-c) before including Windows headers to workaround this issue.
It is highly recommended to [define NOMINMAX](http://stackoverflow.com/questions/4913922/possible-problems-with-nominmax-on-visual-c) before including Windows headers to workaround this issue.
To workaround the incompatibility with these macros, GLM will systematically undef these macros if they are defined.
