RenderToolbox的学习笔记（一）

<style type="text/css"> <!-- @page {margin:0.79in} p {margin-bottom:0.08in} --> </style>

RenderToolbox是由宾夕法尼亚大学（University of Pennsylvania）的David Brainard, [e-mail]; Chris Broussard, [e-mail]开发的一个基于Radiance和PBRT引擎的Matlab工具箱。http://www.rendertoolbox.org/wikka.php?wakka=HomePage

目前RenderToolBox提供了MacOS/X和Linux的安装版本。我们这里只讲下在Ubuntu下的安装。

安装该软件包之前需要安装Radiance，OpenEXR，PBRT，MATLAB，Subversion命令，Psychtoolbox。

1）安装Matlab

http://blog.csdn.net/lqhbupt/article/details/7853440

2）安装Radiance

sudo apt-get install radiance

3）安装OpenEXR

http://blog.csdn.net/lqhbupt/article/details/7854442

4）安装LibTIFF

在官网http://www.libtiff.org/下载文件tiff-3.8.2.tar.gz

sudo tar -zxvf tiff-3.8.2.tar.gz -C /usr/local/

cd /usr/local/ tiff-3.8.2

sudo ./configure

sudo make

sudo make install

（5）安装Psychtoolbox-3

http://neuro.debian.net/

选择相应的Ubuntu版本和镜像后，得到下载NeuroDebian软件库的命令

wget -O- http://neuro.debian.net/lists/precise.jp | sudo tee/etc/apt/sources.list.d/neurodebian.sources.list

sudo apt-key adv --recv-keys --keyserver pgp.mit.edu 2649A5A9

sudo apt-get update

sudo apt-get install mricron

sudo apt-get install octave-psychtoolbox-3

Matlab进入/usr/share/psychtoolbox-3目录

终端命令行输入

sudo chmod a+w -R /usr/local/MATLAB/R2012a/toolbox

在Matlab命令窗口输入：

SetupPsychtoolbox

根据提示，在终端安装缺少的软件。

（6）安装SVN命令

sudo apt-get install subversion

（7）安装RenderToolbox和SimToolbox

sudo mkdir /usr/share/RenderToolbox

sudo mkdir /usr/share/SimToolbox

sudo svn cohttps://platypus.psych.upenn.edu/repos/rendertoolbox/trunk /usr/share/RenderToolbox

sudo svn cohttps://platypus.psych.upenn.edu/repos/simtoolbox/trunk /usr/share/SimToolbox

将RenderToolbox_2.0和SimToolbox加入MATLAB路径

打开Matlab，在命令窗口输入：

>>addpath(genpath('/usr/share/RenderToolbox/RenderToolbox_2.0'));

>>addpath(genpath('/usr/share/SimToolbox'));

>>path(RemoveSVNPaths)

编译安装PBRT_batchRender

打开终端，输入：

cd /usr/share/RenderToolbox/PBRT_batchRender_1.1

sudo make clean

sudo make

将PBRT_batchRender_1.1/bin加入系统环境变量

打开~/.bashrc文件加入如下两行：

export PBRT_SEARCHPATH=”/usr/share/RenderToolbox/PBRT_batchRender_1.1/bin”

export PATH=${PATH}:${PBRT_SEARCHPATH}

编译安装PBRT_original

cd /usr/share/RenderToolbox//PBRT_original

sudo make clean

sudo make

打开PBRT_original目录下的pbrt_org文件，将第一行和最后一行更改为用户的目录。

第一行：

PBRT_SEARCHPATH="/usr/share/RenderToolbox/PBRT_original/bin"

最后一行：

/usr/share/RenderToolbox/PBRT_original/bin/pbrt$*

cd /usr/local/bin

sudo ln -s /usr/share/RenderToolbox/PBRT_original/pbrt_orig .

cd /usr/share/RenderToolbox/Utilities/exrtofloat

sudo make clean

sudo make

cd /usr/local/bin

sudo ln -s /usr/share/RenderToolbox/Utilities/exrtofloat/exrtofloat .

测试RenderToolbox是否安装成功

在Matlab命令窗口

>>cd /usr/share/RenderToolbox/examples/table_sphere

>>unix('./clean.sh');

>>Render_BatchRender
如果一切配置成功，则会在当前文件夹下创建monitor_image_data子文件夹，其中保存分别用Radiance和PBRT渲染出来的图片。

遇到问题及解决方案：

1）core/paramset.h:100:error: extra qualification ‘ParamSet::’ on member ‘ParamSet’

解决方法：在core/paramset.h中，将"ParamSet::~ParamSet()"替换为"~ParamSet()".

film/image_raw.cpp:22:error: extra qualification ‘ImageFilm::’ on member ‘ImageFilm’

解决方法：ImageFilm::ImageFilm(intxres, int yres,前面的ImageFilm::去掉

shapes/sphere.cpp:25:error: extra qualification ‘Sphere::’ on member ‘Sample’

shapes/sphere.cpp:32:error: extra qualification ‘Sphere::’ on member ‘Sample’

shapes/sphere.cpp:59:error: extra qualification ‘Sphere::’ on member ‘Pdf’

解决方法：将对应行的Sphere::去掉

accelerators/kdtree.cpp:98:error: extra qualification ‘KdTreeAccel::’ on member‘KdTreeAccel’

解决方法：将对应行的KdTreeAccel::去掉

2）Lex'ingpbrtlex.l

core/pbrtlex.l:82:bad character:

core/pbrtlex.l:82:name defined twice

core/pbrtlex.l:88:bad character class

core/pbrtlex.l:88:unrecognized rule

core/pbrtlex.l:88:unrecognized rule

core/pbrtlex.l:88:unrecognized rule

core/pbrtlex.l:88:unrecognized rule

core/pbrtlex.l:88:unrecognized rule

core/pbrtlex.l:132:bad character class

core/pbrtlex.l:132:unrecognized rule

解决方法：在core/pbrtlex.l文件中，将第82行修改为

WHITESPACE[ \t\j]+

3）Linkingbin/pbrt

/usr/local/lib/libIlmThread.so:undefined reference to `sem_init'

解决方法：打开Makefile文件，在EXRLIBS=-lIlmImf-lImath -lIex -lHalf -lz

行后添加-lpthread

4）convert.cpp:12:fatal error: ImfRgbaFile.h: No such file or directory

解决方法：打开Makefile文件，将

INCLUDE=/opt/local/include/OpenEXR

LIBDIR=/opt/local/lib

更改为

INCLUDE=/usr/local/include/OpenEXR

LIBDIR=/usr/local/lib
