Learning OpenGL (read a book on OpenGL) can help to develop for Blender?

I would like to know if learn OpenGL can help me to develop for Blender ?
I was thinking, if Blender was wrote with OpenGL, then will be easier learn to develop for Blender ?!

yes, we just impact to this problem.
now i have not enough knowlage of GL to make simple shader + light for Sverchok… but it seems to be basics of OpenGL

Focus on what you are trying to accomplish, your ‘goal’! If it requires knowledge of openGL, then yes, by all means, get to know it.

Basic knowledge of openGL is handy when developing blender but not required. Much of the openGL drawing is done for you and is also very low level. Only delve in when you are required (again depending on your goal).

The OpenGL repo’s are very, very vast, not as straight forward nor easy and getting around very time consuming. question for you is if you want to invest your precious time into getting to know the nitty gritty of openGL…
