Glm::vec2 vs ofVec2f

Question about glm,
Is the idea that we no longer will be using ofVec Should I be using glm::vec3 etc ?

For new projects the recommended is to use glm, for old projects it’s probably easier to keep using ofVec. I wrote a detailed post about it here: http://blog.openframeworks.cc/post/173546759884/glm

That meaning that you can rely on ofVec being there for a long time and whenever it’s completely removed it’ll be in an addon that you can just include in your projects to make them work again

Are most classed in OF using GLM not ofVec like ofPolyline?

all classes in the core are already using glm but addons and examples are still using ofVec
