I am very new to WebGL and am extremely interested in doing some projects with it. I downloaded the OpenGL ES 2.0.25 manual to learn an much as I can. Of course, going to the actual spec for WegGL: https://www.khronos.org/registry/webgl/specs/1.0/ I see all of the references to OpenGL ES 2.0 manual pages. I take it that I must read those manual pages to truly understand what WebGL is/is doing. Is this true?
