OpenGL is low level, that's right, but it is not crap. OpenGL is
hardware independent, and is a true multiplatform standard. The
difference between OpenGL and higher level libraries, like OpenInventor,
it is similar to the difference between a low-level programming language
like C and a higher level object-oriented language, IMHO.

Direct3D it is lower level than OpenGL, and usually needs more
instructions than OpenGL to do the same things.
