Casteljau's Algorithm Demo

A very simple application that highlights how De-Casteljau's algorithm works by showing the intermediate lines used by the algorithm to calculate the resulting bezier curve.

Requirements

In order to compile this demo, you need to have:

• CMake 3.17.0 or a later version (Note: actually even much older versions like CMake-2.8 may also work and if you really need to use an older version simply update the cmake_minimum_required property in your CMake file accordingly).
• Qt-6.5 or later, or Qt-5.7 or later if you enable BUILD_WITH_QT5 for example by running cmake with -DBUILD_WITH_QT5=ON.
• A C++ Compiler with C++-17 support, such as GCC-9 or later.

How to build it

1. Make sure the above mentioned requirements are met.
2. Clone the repository or download an archive and unpack it, then change into the directory.
3. $ mkdir build
4. $ cd build
5. $ cmake ../ (you may also have to add -DCMAKE_PREFIX_PATH or -DBUILD_WITH_QT5 with appropriate values depending on your environment
6. $ make

The resulting executable can then be launched by issuing ./src/de\_casteljau\_demo inside the build directory. If CMake fails to find Qt, you may use the CMAKE_PREFIX_PATH environment variable to help cmake locate the correct version of Qt. Running CMake would then may look like this for Qt5 $ cmake -DCMAKE_PREFIX_PATH=~/Qt/5.15.2/gcc_64 -DBUILD_WITH_QT5=ON .. or the following for Qt6: $ cmake -DCMAKE_PREFIX_PATH=~/Qt/6.5.2 .. (assuming your Qt versions are installed under ~/Qt).
