This library contains SimObjects for visualization and data sharing between programs, primarily for instances of FhSim. Documentation for available SimObjects can be found under modules.
The SimObject Plot/Scope uses Qt and qcustomplot. The implementation is minimal, but functional: you can plot simulation time series alongside the 3D visualization. Plot/Scope now support the ability to create multiple SimObject plotting instances. Plot/Scope also have the capability to create animation png frames.
Suppose you have run a simulation with Plot/Scope, which created a set of animation frames ScopusDdsXXXX.png in folder animations. You can use imagemagick >= 7.0.10-31 to compose an animated png using the following commands, see StackOverflow reference for details. Download and install imagemagick.
Delay is given in centiseconds, so with 30 frames per second (FPS), delay is
\[d = \frac{100}{\text{FPS}} = 3.33.\]
The Connection SimObjects are made for data sharing using a simple wrapper around Data Distribution Service OMG DDS. The reader and writer classes are made for sharing double vectors.
It uses ratatosk/interfaces/DdsSignalDllLib.h, which is part ofratatosk-interfaces. The library can be used in other C++ applications too, or directly in e.g. python with pyDDS. This package has a sample application dds-producer that shows how external applications can be used to send data to an FhSim simulation. See the README_dds_producer.md in the playpen binary folder. Please consult SINTEF Ocean and Marine Modeling and Analysis (Karl-Johan Reite) for details on the published data type.
