vdb_cmd

Commands that manipulate OpenVDB sparse volume files.

Getting started

Ensure you have OpenVDB installed. Below are steps to take to install it on a Mac.

git clone https://github.com/AllwineDesigns/vdb_cmd.git
cd vdb_cmd
make

Commands

stl2vdb

stl2vdb [-v ]

Rasterizes an STL mesh into an OpenVDB sparse volume levelset grid with the provided voxel size. If the voxel size is omitted, it defaults to .5.

vdb2stl

vdb2stl [-d ]

Convert an OpenVDB sparse volume levelset grid to an STL mesh with the provided detail (0-1). If detail is omitted, it defaults to .9.

vdb_boolean

vdb_boolean -a <VDB file A> -b <VDB file B> [ -i ] [ -u ] [ -d ] <out file>

Performs a CSG boolean operation on VDB levelset grids A and B. -i will perform the intersection of A and B. -u will perform the union of A and B. -d will perform the difference of A and B.

Install Steps for Mac

# Install most dependencies with homebrew
brew install boost
brew install tbb
brew install openexr
brew install ilmbase
brew install cppunit
brew install log4cplus
brew install glfw
brew install doxygen

# install blosc from source
curl -L https://github.com/Blosc/c-blosc/archive/v1.12.1.tar.gz -o c-blosc-1.12.1.tar.gz
cd c-blosc-1.12.1
mkdir build
cd build
cmake -DCMAKE_INSTALL_PREFIX=/usr/local ..
cmake --build .
ctest
cmake --build . --target install

Edit Makefile

Change DESTDIR to /usr/local

Change Homebrew paths

  • boost - /usr/local/Cellar/boost/<version>/
  • tbb - /usr/local/Cellar/tbb/<version>/
  • openexr - /usr/local/Cellar/openexr/<version>/
  • etc.
  • python - /usr/local/Cellar/python/<version>/Frameworks/Python.framework/Headers

Change Source paths

  • blosc - /usr/local/

Comment out CONCURRENT_MALLOC_LIB := -ljemalloc

Uncomment CONCURRENT_MALLOC_LIB := -ltbbmalloc_proxy -ltbbmalloc

Set CONCURRNET_MALLOC_LIB_DIR to $(TBB_LIB_DIR)

Comment out python

Change libboost_thread to libboost_thread-mt
