Pixar RenderManのPython APIとcgkitでの記述を並べてみた。
import prmanでは、パラメータを辞書形式で記述。後はほとんど同じ感じてす。
以下は、ティーポットの表示
■import prman

#test2.py

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

import prman

ri=prman.Ri()

rendertarget="test2.rib"

ri.Begin(ri.RENDER)

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

ri.Display("teapot2.png", "file", "rgb")

ri.Format(640,480,1)

ri.Projection(ri.PERSPECTIVE, {ri.FOV: 45})

ri.Translate(0,0,10)

ri.WorldBegin()

ri.LightSource("pointlight", {ri.HANDLEID: "1", "from": [-10,10,-10],"intensity":[300]})

ri.LightSource("pointlight", {ri.HANDLEID: "2", "from": [10,10,-10],"intensity":[300]})

ri.LightSource("pointlight", {ri.HANDLEID: "3", "from": [-10,-10,-10],"intensity":[300]})

ri.Color((0.9,0,0.1))

ri.Surface("plastic")

ri.Translate(0,-1,0)

ri.Rotate(-90,1,0,0)

ri.Geometry("teapot")

ri.WorldEnd()

ri.End()

■cgkit
3Delightを利用した。

#min2.py

import cgkit.cri



ri = cgkit.cri.loadRI("3Delight")

cgkit.cri.importRINames(ri, globals())



RiBegin(RI_NULL)

RiImager("background", "color background",(.2,.4,.6))

RiDisplay("min2.png", RI_FILE, RI_RGB)

RiProjection(RI_PERSPECTIVE,RI_FOV,45)

RiTranslate(0,0,10)

RiWorldBegin()

#RiLightSource("ambientlight","intensity",0.4)

#RiLightSource("distantlight")

RiLightSource("pointlight", RI_HANDLEID, "1", "from",[-10,10,-10],"intensity",[300])

RiLightSource("pointlight", RI_HANDLEID, "2", "from",[10,10,-10],"intensity",[300])

RiLightSource("pointlight", RI_HANDLEID, "3", "from",[-10,-10,-10],"intensity",[300])

RiSurface("plastic")

RiColor((1,0.2,0.2))

RiTranslate(0,-1,0)

RiRotate(-90,1,0,0)

RiReadArchive("teapot.rib")

RiWorldEnd()

RiEnd()
