###Simple Templated Mathematics Library for 3D Graphics

####How to compile:

cd path/to/3DTools
mkdir build && cd build
cmake ..
make

• Optional CMake options:
  1. BUILD_TEST (ON/OFF) - Determine to either build tests or not. Defaults to OFF.
  2. BUILD_EXAMPLES (ON/OFF) - Specify whether you want to build tests or not. Defaults to OFF.

####How to use:

• You can just edit the CMakeLists.txt and include the headers to your project (after all it is just a header library).
• Via ExternalProject to always get latest edition:

   include(ExternalProject)
   ExternalProject_Add(3DToolsProj
       GIT_REPOSITORY "https://github.com/costashatz/3DTools"
       CMAKE_ARGS -DBUILD_TEST=OFF -DBUILD_EXAMPLES=OFF
       PREFIX "${CMAKE_CURRENT_BINARY_DIR}"
       INSTALL_COMMAND ""
   )
   # Specify include dir
   ExternalProject_Get_Property(3DToolsProj source_dir)
   set(3DTOOLS_INCLUDE_DIRS ${source_dir}/include)
  
   # Specify MainTest's link libraries
   ExternalProject_Get_Property(3DToolsProj binary_dir)
   set(3DTOOLS_LIBS_DIR ${binary_dir})
  
   link_directories(${3DTOOLS_LIBS_DIR})
   include_directories(${PROJECT_SOURCE_DIR}/include ${3DTOOLS_INCLUDE_DIRS})
   ....
   target_link_libraries(mytarget 3DTools)

####So far I have implemented:

1. Vector3D
   • Simple Class for handling Vectors and Points (maybe needs fourth component and new class for Points)
2. Matrix3D
   • Simple Class for 4x4 Matrices needed (now is column major representation and multiplying with a vector by either side has the same effect)
3. Simple Unit Tests with gtest

####Planning to implement:

1. LinearShapes
   • Simple Classes for Linear Shapes (Line, Ray, Segment)
2. PlanarShapes
   • Planes, e.t.c.
3. Polymeshes, Polyhedra, Polytopes
4. Quadratic Surfaces
   • Three nonzero eigenvalues, two nonzero eigenvalues, one nonzero eigenvalue
5. Polynomial Curves
   • Bezier
   • B-Spline
   • NURBS
6. Intersections3D
   • Find intersections (intersection area, points, true/false) between all the 3D primitives/shapes above
7. Distances3D
   • Find distances between shapes/primitives
8. BSP Trees in 3D
9. Miscellaneous Topics in 3D
   • Convex Hulls
   • Triangulation
   • Area/Volume Measurement

####So far I have tested and are working properly:

1. Vector3D
2. Matrix3D

####WORK IN PROGRESS - WILL BE UPDATED FREQUENTLY

I am currently working on this little library and will be pushing more updated stuff. Any suggestions of course are more than welcomed.
