1. Double-Down installation

1.1. Installing Manually

Double-down relies on the Mesh-Oriented datABase (MOAB) for reading and storage of the surface mesh. As discussed in Theory and Methodology, Intel’s Embree is then used build a bounding volume hierarchy (BVH) around the surface primitives. Each of these packages must be installed prior to using double-down. Please refer to the respective package installation guides to install these required codes.

The location of the MOAB and Embree installs can be provided via the CMAKE_PREFIX_PATH variable in the cmake command. An example of the commands used to clone, configure, and build double-down might look like this:

# clone the repo
$ git clone https://github.com/pshriwise/double-down
$ cd double-down
# configure the build
$ mkdir bld
$ cd bld
$ cmake .. -DCMAKE_INSTALL_PREFIX=/my/install/location -DCMAKE_PREFIX_PATH="/moab/install/location;/embree/install/location"
# build and test double-down
$ make all test
# install
$ make install
