does jit.gl.lua support 1- or 2-d evaluators or mapgrids for building splines and nurbs from scratch. if so what is the translation from redbook opengl?

for example i tried this redbook example, but it did not work

gl.Map1("MAP1_VERTEX_3", 0.0, 1.0, 3, 4,ctrlpoints) 

does jit.gl.lua support 1- or 2-d evaluators or mapgrids for building splines and nurbs from scratch. if so what is the translation from redbook opengl? 

ctrlpoints = { 
    { -4.0, -4.0, 0.0}, { -2.0, 4.0, 0.0}, 
    {2.0, -4.0, 0.0}, {4.0, 4.0, 0.0}} 

    gl.ClearColor(0.0, 0.0, 0.0, 1.0) 
    gl.Map1("MAP1_VERTEX_3", 0.0, 1.0, 3, 4,ctrlpoints) 
    gl.Enable("MAP1_VERTEX_3") 
    gl.ShadeModel("FLAT") 

    gl.Color(1.0, 1.0, 1.0) 
    gl.Begin("LINE_STRIP") 
	for i = 0,30 do
          gl.EvalCoord(i/30.0) 
	end
    gl.End() 

Evaluators/mapgrids in LUA?
