至于infinigen是什么，网上很多，这篇文章主要是我安装的记录

官网：https://infinigen.org/
github：https://github.com/princeton-vl/infinigen

安装

首先要配置wsl环境，如何配置wsl，可以关注公众号“科技探幽”，回复"wsl"获取教程，然后在Ubuntu中运行下面的命令

git clone --recursive https://github.com/princeton-vl/infinigen.git
cd infinigen
conda create --name infinigen python=3.10
conda activate infinigen
bash install.sh

修改环境变量，增加BLENDER

# on Linux/WSL
export BLENDER="/PATH/TO/infinigen/blender/blender"
# on MAC
export BLENDER="/PATH/TO/infinigen/Blender.app/Contents/MacOS/Blender"

要注意BLENDER命令时，前面的符号也要加上$BLENDER

cd worldgen
mkdir outputs

# Generate a scene layout
$BLENDER -noaudio --background --python generate.py -- --seed 0 --task coarse -g desert simple --output_folder outputs/helloworld/coarse

# Populate unique assets
$BLENDER -noaudio --background --python generate.py -- --seed 0 --task populate fine_terrain -g desert simple --input_folder outputs/helloworld/coarse --output_folder outputs/helloworld/fine

# Render RGB images
$BLENDER -noaudio --background --python generate.py -- --seed 0 --task render -g desert simple --input_folder outputs/helloworld/fine --output_folder outputs/helloworld/frames

# Render again for accurate ground-truth
$BLENDER -noaudio --background --python generate.py -- --seed 0 --task render -g desert simple --input_folder outputs/helloworld/fine --output_folder outputs/helloworld/frames -p render.render_image_func=@flat/render_image 

拷贝文件到我的电脑上

scp -P 8888 ubuntu@127.0.0.1:/home/xx d:\xxx\xx

错误

运行下面这条命令时，我的电脑报错了，如下

$BLENDER -noaudio --background --python generate.py -- --seed 0 --task coarse -g desert simple --output_folder outputs/helloworld/coarse

错误如下

Blender quit

主要是由于缺少了文件

运行下面的命令构建SoilMachine.so文件

 sudo apt install libglm-dev
  cd worldgen/terrain
  chmod +x install_terrain.sh
  ./install_terrain.sh
