Lightflow Rendering Tool C API for Linux 2018/10

2018/10/22記述
2020/5/12更新

LightflowのC APIについて、動いたLinux distributionを調べました。

Fedora28(64bit)をインストールしたノートパソコン(2012年 W255HPW)にVirtualBox5.2.20をインストール。

32bitのLinuxをいくつかインストールしました。
Lightflow C APIが動いたのは、
VineLinux2.6(include python1.5, gcc2.95)
VineLinux3.2
VineLinux4.0
VineLinux4.2
VineLinux5.2
CentOS5.11
ここまで、画面が800*600で狭いのが難点。

Fedora32(64bit)にGnome Boxesを入れ、
Fedora-8-i386をインストール。
python1.5,gcc2.95,Lightflow動きました。
Lightflow C APIも動きました。
Linuxは、gccが4.1.2のディトりビューションが良いみたいです。2020/5/12追記

動かなかったのは、
Scientific Linux6 i386
Fedora28 32bit

//** インストール方法
http://www.python.org/download/releases/1.5/
Python 1.5.2 sources (2.5 MB)をダウンロード
■python1.5.2をインストール。
$ ./configure
$ make
# make altinstall

■さらに次のファイルをダウンロードします。
compat-libstdc++-6.2-2.9.0.14.i386.rpm
http://rpm.pbone.net/index.php3/stat/4/idpl/14760/com/compat-libstdc++-6.2-2.9.0.14.i386.rpm.html

■gcc-2.95.3をインストール。
インストール先のディレクトリを作成しておく。
# mkdir /usr/local/gcc-2.95
$ ./configure --prefix=/usr/local/gcc-2.95 --enable-languages=c,c++
$ make
# make install
確認
$ /usr/local/gcc-2.95/bin/g++ --version
2.95.3

■Lightflowのダウンロード
Lightflowのサイトから
http://www.lightflowtech.com/

Linux RedHat 6.1 Version (1608 Kb)
lf_redhat.tgzをダウンロードします。
/home/ユーザ/Lightflow
で解凍します。

.bash_profileまたは.bashrcに記入
LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$HOME/Lightflow
PYTHONPATH=$PYTHONPATH:$HOME/Lightflow
LIGHTFLOWPATH=$HOME/Lightflow
LIGHTFLOW_SE_MEMORY=32000
LIGHTFLOW_VE_MEMORY=32000

export LD_LIBRARY_PATH PYTHONPATH LIGHTFLOWPATH LIGHTFLOW_SE_MEMORY LIGHTFLOW_VE_MEMORY

以下を実行するとpython1.5でレンダリングできました。
Examples]$ python1.5 ball1.py

■C APIの設定。
http://www.knoerig.de/lightflow_en.html
「Rudi's Homepage - Lightflow」を参考にincludeファイルをダウンロードします。

$ mkdir simplescene
includeファイルを置きます。

C++-libraryをシンボリックリンクします。
# ln -s /home/ユーザ/Lightflow/libLightflow.so /usr/lib

以下Makefile



CC = /usr/local/gcc-2.95/bin/g++ 

INCLUDE=-I ./include

LNK = -lLightflow

CNV = convert

ball.jpg: ball.tga

	$(CNV) ball.tga ball.jpg

	$(CC) $(INCLUDE) $(LNK) main.cpp -o simplescene

main.cpp



#include < Lightflow/LfLocalSceneProxy.h >

#include 



int main()

{

    // create a new proxy

    LfLocalSceneProxy *s = new LfLocalSceneProxy();

    // this is a container object for storing the arguments passed to 

    // the renderer via the proxy

    LfArgList list;

    

    // define a light

    list.Reset();

    list << "position" << LfVector3(-4,-7,6);

    list << "color" << LfVector3(450*1.0,450*1.0,450*0.8);

    LfInt light = s->NewLight("soft",list);

    s->LightOn(light);

    

    // define a material (standard material, there are others)

    list.Reset();

    // ambient color

    list << "ka" << LfColor(0,0,0.5);

    // reflection color

    list << "kc" << LfColor(1,0.5,0.5);

    // diffuse reflection factor

    list << "kd" << 0.5;

    // specular reflection smoothness (0-polished,1-plastic)

    list << "km" << 0.1;

    // surface displacement

    // LfInt is a long int representing a handle

    LfInt plastic = s->NewMaterial("standard",list);

    

    // define a sphere object

    s->MaterialBegin(plastic);

    list.Reset();

    list << "radius" << 1.0;

    LfInt ball = s->NewObject("sphere",list);

    s->AddObject(ball);

    s->MaterialEnd();

    

    // specify the output object

    list.Reset();

    list << "file" << "ball.tga";

    LfInt saver = s->NewImager("tga-saver",list);

    

    // specify the rendering context

    s->ImagerBegin(saver);

    list.Reset();

    // camera position

    list << "eye" << LfPoint(0,-4,0);

    // point to aim at

    list << "aim" << LfPoint(0,0,0);

    LfInt camera = s->NewCamera("pinhole",list);

    s->ImagerEnd();

    

    // start rendering

    s->Render(camera,300,300);



    delete s;

    return 0;

}

一時的にPATHを通しても良いです。
$ export PATH=/usr/local/gcc-2.95/bin:$PATH

makeします。
$ make simplescene
$ ./simplescene

Lightflowを設定していくことで、Linuxの勉強になりました。
ありがとうございます。

wine-3.6 (Ubuntu 3.6-1) install under Linux Lite.　2020/5

Wineのインストール

Linux Lite4.2 64bitにwineをいれました。
Windows10では動かない、Lightflowやmetalight2が動くか確認した見ました。インストールは64bitですが、32bitのwinアプリが動きました。
■参考
下記を参考にしました。ありがとうございます。
ガラクタプログラム

■設定
Linux Liteを,virtualbox上で動かしています。

$ apt-file search winehq
たくさん、出てきます。
$ sudo apt-get update

$ sudo apt install wine-development

$ wine
Usage: wine PROGRAM [ARGUMENTS...] Run the specified program
wine --help Display this help and exit
wine --version Output version information and exit

$ wine --version
wine-3.6 (Ubuntu 3.6-1)

■設定方法
まずwinecfgを起動します。しばらく時間がかかる。
$ winecfg
$ wine notepad メモ帳
$ wine regedit　レジストリ・エディタ

■Winetricksを使って必要なライブラリやフォントなどをインストールします。
$ sudo apt install winetricks
$ winetricks
Direct3D9をいれてみました。

■VirtualBox共有フォルダ
ubuntu系
sudo nano /etc/modules
cat /etc/modules
# /etc/modules: kernel modules to load at boot time.
#
# This file contains the names of kernel modules that should be loaded
# at boot time, one per line. Lines beginning with "#" are ignored.
vboxsf
--------------

ゲストOSに$mkdir <マウントポイント名＞
フォルダを作る。

＄sudo mount.vboxsf <設定したホストOSでの共有ファイル名> /home/<ログインに使う名前>/<マウントポイント名>

例: ~$ sudo mount.vboxsf kyouyu /home/mac/litekyouyu/

■バージョン確認
$ cat .wine/system.reg | grep -m 1 '#arch' | cut -d '=' -f2
win64

■古いプログラムが起動する。ありがとうございます。
インストーラーも、起動してCドライブに入ります。Python1.5.2をインストールしました。
$ wine py152.exe
Python1.5.2 for windows のインストール。

$ wine cmd
コマンドプロンプト

$ wine explorer
Windows のコマンドプロンプトからエクスプローラを開く
Windows のファイルマネージャーはエクスプローラ (explorer.exe)
コピー、貼り付けがゆっくりですが、できました。

■Wine上の環境変数の設定
「Wine上の環境変数の扱いについて(後半)」を参考にしました。
$ wine regedit
を使います。
ユーザごとの環境変数はHKEY_CURRENT_USER/Environment、(仮想Windows環境における)システム環境変数はHKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Environment以下に「[環境変数名]=[値]」形式の文字列としてレジストリ項目が存在する場合にこれを読み込む形となっている。

保存し、再起動して、確認、PATHが追加されました。
c:\Lightflow\PM\Examples>path
PATH=C:\windows\system32;C:\windows;C:\windows\system32\wbem;C:\Program Files (x86)\Python

これで、64bit環境で、windows 32bitプログラム、Lightflow Rendering Toolが動きました。
Lightflowのインストールはこちら。

Furry_bunny by Fujiyama Renderer 0.3.6

解像度160*120で何度もレンダリングしました。
8年前、5万6千円で購入したノートpc、Linux Fedora 32を入れて、fujiyama Renderer 0.3.6で、stay home, うさぎモデルfurry_bunny、52分41秒かかりました。HDR素材は@cgphysical_i
さんサイトを利用しました。
DomeLightのintensityを2.0にしました。

Primitive group in Fujiyama Renderer

feature since v0.2.9
-------------------------------------------------
* Mesh primitive group has been supported. Different shaders can be assigned to each primitive group. Shading group tagged by 'g' in wavefront obj file is converted to primitive group in Fujiyama.
