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