夏老师一张嘴就是我从90年就开始教这门课_(:зゝ∠)_喵的,比我活的时间都久.蜜汁感慨.

OpenGL,OpenCV and WebGl’s difference

OpenGL(Open Graphics Library) focuses on drawing graphics that make sense to humans.

OpenCV(Open Computer Vision)’s work is finding useful info from graphics in a computer’s way.
so,this two are entirely different things.In another word,their endgames are almost opposite.

OpenGL ES:a smaller and better vision of OpenGL.can be used on mobiles,such as iOS and Android.

WebGl:can be used on web,can be very interactive with HTML5, JS, native ect.

Three.js:(Javascript 3D Library)a third-party lib for WebGL written by Javascript.

On Windows, DirectX is way better than OpenGL. However OpenGL is wildly used on mobiles.
