イギリスのbournemouth universityを参考にしました。ありがとうございます。Thank you.
import prman使ってます。

#ricurve_pr.py

#set PYTHONPATH=C:\Python25;C:\Python\Scripts;%RMANTREE%\bin

import prman

ri=prman.Ri()



filename="ricurve_pr.rib"



ri.Begin(ri.RENDER)

ri.Imager("background", {"color color":(.2,.4,.6)})

ri.Display ("ricurve_pr.png","file","rgb")

ri.Format(512, 384, -1.0)

ri.PixelSamples( 4, 4)

ri.ShadingRate(1)

ri.Projection(ri.PERSPECTIVE, {ri.FOV: 90})

ri.WorldBegin()

ri.LightSource("distantlight", {ri.HANDLEID: "1","to":[0,0,1]})

ri.LightSource("ambientlight", {ri.HANDLEID: "2", "intensity":[0.4]})

ri.Translate(0,0,1.8)

ri.Surface("plastic")



ri.Color([1,0,0])

points= [0, 0, 0 ,-1, -.5 ,1 ,2 ,.5 ,1 ,1 ,0, -1 ]

width=[0.01,0.04]

ri.Curves( "cubic",[4],"nonperiodic",{ri.P:points, ri.WIDTH : width})



ri.Color([0,0,1])

points2=[0,0,0,3,4,5,-1,-.5,1,2,.5,1,1,0,-1]

ri.Curves("linear",[5],"nonperiodic",{ ri.P:points2 , ri.CONSTANTWIDTH:[0.075]})



ri.WorldEnd()

ri.End()
