はじめてのFujiyama Renderer その8 視野変換
とりあえず、カメラ位置と注視点位置から視野変換するPythonスクリプトをRenderMan資料placecam.cを参考に求めてみました。ありがとうございます。
まちがっているところもあるかもしれませんが、それっぽくカメラ位置が求められています。
Fujiyama Rendere0.1.1では、変換の順序は、プロパティを設定する順序に
影響しません。記述の順番は関係しません。
順序を設定するためのプロパティは'transform_order'、
'rotate_order'になり、デフォルトではそれぞれ、ORDER_SRTと
ORDER_XYZになっています。
変換はスケール、回転、移動の順に行われています。
回転はx,y,z軸回転の順に行われています。
以下のfujicam.py、Pythonスクリプトを実行し、出力された変換をコピペでシーンに張り付けてください。なおroll、coneangleは未対応です。

はじめてのFujiyama Renderer その11
python cgkitを使ってFujiyama Rendererのサンプル内の32個のPointLightの位置を確認してみました。
cgkitのviewer.pyで確認したところ、四角形の対角になるような斜め配置になっていました。
cgkitのrender.pyを使ってレンダリング確認、画像は3Delightで生成しました。

POV-Rayのdefault cameraのangleを求める
以下、Pov-rayでは未検証ですが、計算してみました。
パースペクティブ・カメラの主なディフォルト設定（省略するとこの設定値が使用されている。）
camera {
perspective
location <0,0,0>
direction <0,0,1>
right <1.33,0,0>
sky <0,1,0>
up <0,1,0>
look_at <0,0,1>
}
画角（angle）
angle、right、directionの関係は次式で表される（right_lengthとdirection_lengthはそれぞれrightとdirectionベクトルの長さ）。
direction_length = 0.5 * right_length / tan(angle / 2)
デフォルトカメラのangleは、
1=0.5*1.33/ tan(angle / 2)
tan(angle / 2)=0.5*1.33
angle / 2=atan(0.5*1.33)
angle=2*atan(0.5*1.33)
で求められるので、以下python cgkitで求めてみました。
>python
Python 2.6.5 (r265:79096, Mar 19 2010, 18:02:59) [MSC v.1500 64 bit (AMD64)
win32 Type "help", "copyright", "credits" or "license" for more information.
>>> from cgkit.all import *
>>> right=vec3(1.33,0,0)
>>> right.length()
1.3300000000000001
>>> direction=vec3(0,0,1)
>>> direction.length()
1.0
>>> import math
コサイン60度を求めてみる。1/2になるかな。
>>> math.cos(math.radians(60))
0.50000000000000011
アークタンジェント：ａｔａｎ（ｘ） を求める。
>>> 2*math.atan(1.33*0.5)
1.1736957392994543
ラジアンを度に変換する。
>>> math.degrees(2*math.atan(1.33*0.5))
67.247812294345678
>>> angle=math.degrees(2*math.atan(1.33*0.5))
>>> angle
67.247812294345678
ということで67度となりましたが、あっているかどうかは
実際POV-RAYで検証しなくてはなりません。
Fujiyama Renderer dome light with HDRI
HDRIを使うdomelightを試してみた。
120フレームをレンダリングするために12ファイル作り12スレッドで各ファイルは10フレームレンダリングする。レンダリング時間は約40分でした。
