[Solved] CIS410 Project 4

Assignment:1) Download skeleton file proj4.cxx and data file proj4_data.vtk and put them ina new directory.2) Re-use your CMakeLists.txt from the last project.3) Compile the program and run the program. It will generate incorrect output.4) You will need to implement three functions to make it generate the correctoutput (search for IMPLEMENT ME)a. You should evaluate them in the following order:i. EvaluateVectorFieldAtLocation1. Note that the first print statements test this routine.(You can be testing this one before proceeding.)ii. AdvectWithEulerStepiii. CalculateArcLength1. Note that the second print statements use this routine.If they match my output, you almost certainly didAdvectWithEulerStep correctly.5) Update your source code and a screenshot of your output to Canvas when itis working. The screenshot should include the text output and visual output.The correct text and visual outputs are provided.a. If you are submitting incorrect answers, please reference this in yoursubmission.b. Please keep in mind that incorrect answers are likely to receive <50%.I would rather have a correct answer late than an incorrect answer ontime.Note: we have discussed vector fields that change over time. This is calledunsteady state flow and is what occurs in the real world. We also discussed thenotion of steady state flow vector fields that dont change over time. For thisassignment, we will use steady state flow. From the implementation perspective,it means you can drop the time component when doing velocity interpolation.
