guile-rmanでのRiPolygonの表記がわかりました。RiPointsもわかりましたが"width"設定がわからないところ。

以下はサンプルです。points.scmで保存しました。

#!/usr/bin/guile -s

!#



(use-modules (rman rispec))

(use-modules (rman utilities))



(RiBegin "points.rib")

  (RiDisplay "points.tif" "file" "rgb")

  (RiFormat 640 480 1)

  (RiProjection "perspective" '("fov" 30))

  (RiTranslate 0 0 3)

;  (RiProgressHandler progress)

  (RiPixelFilter RiBoxFilter 1 1)

  (RiWorldBegin)

      (RiLightSource "ambientlight" (list "intensity" 0.2))

      (RiLightSource "distantlight" (list "intensity" 1.2 ))

      (RiAttributeBegin)

      (RiColor (Color 1 0 0))

      (RiSurface "plastic")

      (RiTransformBegin)

      (RiTranslate -0.5 -0.5 0)

      ;;(RiRotate -90 1 0 0)

      ;;(RiDisk 0 0.5 270)

      ;;(RiCone 1 0.5 150)

      ;;(RiCone 1.5 0.5 360)

      (RiPolygon 4 (list "P" #f32(0 0 0 0 1 0 1 1 0 1 0 0)))

      ;;(RiPoints 4 (list "P" #f32(0 0 0 0 1 0 1 1 0 1 0 0) "width" 0.25)) ;;"Cs" #f32(1 0 0 0 1 0 0 0 1 1 1 0) "width" #f32(0.25 0.25 0.25 0.25)

      (RiTransformEnd)

      (RiAttributeEnd)

  (RiWorldEnd)

(RiEnd)

(RiPoints 1 (list "P" #f32(0 0 0)))
で原点に点を表示します。
