Thanks Pat, I have searched for information about the live-data feature, but I found only two interesting links : http://www.vtk.org/Wiki/ParaView:Live_Data_Introduction and http://www.vtk.org/Wiki/Animating_Live_Data In my case, the generating data program is a car embedded platform programming with C++/Qt. It contains a main program that manage many processes. Each process can be launched to do a particular feature and can communicate together with shared memories. For example, there is a process that reads vehicle speed from car network (CAN bus) and saves data into a shared memory. Another process uses this data to do some treatments with other data. The car is equipped with others sensors as radar, or lidar, or camera... and an process save data into the shared memory. The goal of my project is to create a process that read some data in many defines shared memories and to send this data to Paraview so that it displays for example a graph of speed changes and a representation of the car environment thanks to the radar and other data that we can choose before launching the process. So the process must be available to launch Paraview, open a predefined configuration and send in real time all data read into shared memories. For now, I have only played with Paraview thanks to some tutorials, but each time, data comes from a fixed file. First I would like develop a simple process that send the vehicle speed (a float number) and displays the value in a graph view into Paraview. Where can I found Paraview sources that use live-data ? Is there an example of program that interface with paraview library and send live-data ? Thank you in advance for your help.
