AABBtree

AABBtree is a library for the construction and manipulation of axis-aligned bounding box (AABB) trees. The library is designed to be used in the context of collision detection, and other applications that require the efficient computation of intersections between axis-aligned bounding boxes. It provides a simple and intuitive interface for the construction of AABB trees from a set of axis-aligned bounding boxes, as well as for the computation of intersections between AABB trees, individual AABBs, and points. The library is implemented in C++17 and is header-only, meaning that it can be easily integrated into existing C++ projects without the need for additional dependencies. This fast and efficient library is implemented in C++17 and is header-only, meaning that it can be easily integrated into existing C++ projects without the need for additional dependencies or compilation steps.

Installation

Quick and dirty

AABBtree is an header-only library that depends only on CMake (version >= 3.14).

CMake

If you are using CMake, you can add the library as a subdirectory in your project.

add_subdirectory(path/to/AABBtree)
target_link_libraries(your_target PRIVATE AABBtree::AABBtree)

You can use FetchContent to download the library from GitHub.

include(FetchContent)

# Optionally specify a custom path to fetch content to
set(FETCHCONTENT_BASE_DIR "path/to/your/dependencies")
fetchcontent_declare(
  AABBtree
  GIT_REPOSITORY https://github.com/StoccoDavide/AABBtree.git
  GIT_TAG        main
)
fetchcontent_makeavailable(AABBtree)
target_link_libraries(your_target PRIVATE AABBtree::AABBtree)

If you already have AABBtree somewhere on your system, you can use find_pacakge directly.

# Optionally specify a custom path to find content from
list(APPEND CMAKE_PREFIX_PATH "path/to/your/dependencies")
find_package(
  AABBtree
  ${YOUR_DESIRED_AABBTREE_VERSION}
  NO_MODULE
)

target_link_libraries(your_target PRIVATE AABBtree::AABBtree)

Since we are nice people, we also show you how to conditionally use FetchContent based if you already have the library or not.

# Optionally specify a custom path to find content from
list(APPEND CMAKE_PREFIX_PATH "path/to/your/dependencies")
find_package(
  AABBtree
  ${YOUR_DESIRED_AABBTREE_VERSION}
  NO_MODULE
)

if(NOT TARGET AABBtree::AABBtree)
  include(FetchContent)

  # Optionally specify a custom path to fetch content to
  set(FETCHCONTENT_BASE_DIR "path/to/your/dependencies")
  fetchcontent_declare(
    AABBtree
    GIT_REPOSITORY https://github.com/StoccoDavide/AABBtree.git
    GIT_TAG        main
  )

  fetchcontent_makeavailable(AABBtree)
endif()

target_link_libraries(your_target PRIVATE AABBtree::AABBtree)
