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 <glm/glm.hpp> or other GLM include.
