  • How to draw NURBS with modern OpenGL (non glu), C++

    From JiiPee@21:1/5 to All on Thu Aug 29 11:51:00 2019
    How to draw NURBS with modern OpenGL without using glu functions on C++ language? Is there any functions other than glu versions I can use to do
    it? Or do I need to just find the NURBS points and draw small lines?
    What is the correct approach drawing NURBS with modern OpenGL (using
    buffers)?


    Is there any OpenGL C++ libraries doing this I could download or I have
    to implement it myself?

    There is

    http://libnurbs.sourceforge.net/

    but it may be slow.
    As far as i know, FreeWRL uses it for NURBS rendering, but it is
    remarkable slower for a lot contolPoints, at least it is slower than
    other X3D browsers of white_dune.

    so long
