GreasePad
Freehand Drawing guided by Geometric REASoning
The GreasePad provides a drawing area and expects pen strokes as the only user input. These strokes are approximated by straight line segments leading to line drawings. During this interactive process, geometric relations such as orthogonallity are recognized and enforced immediately by an adjustment process. The program can be utilzed to study systems of straight lines and constraints (closure theorems) or to outline the shapes of human-made objects in images. As a pointing device, you can use a computer mouse, or - in combination with a touchscreen - a stylus or one of your fingers.

Requirements
For the compiliation and building of the programme, the following components are required:
- The C++ template library Eigen, version 3.4.0, for linear algebra, i.e, matrices, vectors, numerical solvers, and related algorithms.
- The widget toolkit Qt, version 5.11.0, for creating the graphical user interface.
Building from source
- Get the Qt toolkit and the Eigen library,
e.g., via
bash git clone https://gitlab.com/libeigen/eigen.git Clone the source code, i.e.,
bash git clone https://www.github.com/FraunhoferIOSB/GreasePad.gitBuilding the programme, e.g., using the integrated development environment QtCreator or using CMake with the file CMakeLists.txt.
