Helloworld project of Pixar USD in C++

Introduction

I hope to develop a conversion tool with pixar usd for our own DCC software zeno. After learning the tutorial officially provided by usd, I hope to start a c++ usd project. However, there is a lack of c++ usd resources on the network, and even running a helloworld is very difficult. I provide the helloworld project I obtained after practice here, so that the required usd learners can use it.

Pre-requriements

Install pixar usd properly, follow the official build instructions.

Add environment variable. Example in Linux with zsh:

echo "export USD_INSTALL_ROOT=/usr/local/USD" >> ~/.zshrc
source ~/.zshrc

/usr/local/USD is my USD install directory, make sure it matches yours.

Edit cmake file

We need to link a lib names libboost_python.so, but the name of this lib rely on the python version runs the USD install script. In my system, it names libboost_python38.so, You can use this command to find out the name of this lib.

ls /usr/local/USD/lib | grep 'libboost_python'

Modify CMakeLists.txt line 28 to make sure the lib's name matches yours.

Have fun

Now you can start your c++ usd project. You can directly compile and run exist program in this repo.

cmake -B build
cmake --build build
cd build && ./run_it
usdview helloworld.usda
