OutInfo.Append(executive.TIME_STEPS(), timestep) "helper routine to set timestep information" Output.Points = (+).Tĭef setOutputTimesteps(algorithm, timesteps): Ts= outInfo.Get(executive.UPDATE_TIME_STEP()) OutInfo = executive.GetOutputInformation(0) Roll=float(-input1.PointData*numpy.pi/180) Pitch=float(input1.PointData*numpy.pi/180) Yaw=float(-input1.PointData*numpy.pi/180) #get cog and angles from the cvs file (TableToPoints) TableToPoints should have Keep All Data Arrays ticked The key point is to avoid loops and use numpy dot product with broadcasting. Z : rotate around ZYX with psi, theta, phi Y : rotate around ZYX with psi, theta, phi X : rotate around ZYX with psi, theta, phi The code boils down to a loop over the mesh points and a set of standard matrix transformations of the form I have written a programmable filter to perform Euler transformations based on a poly data set and a csv input.

How to speed up point loop in programmable filter ParaView Support Is it possibly to simply use the inputs.Points vector and rotate and translate it using custom transformations?

ideally I would like to do the rotations and translations myself and simply update the coordinates of the geometry without going through the built in Transform functions, perhaps the programmable filter is the solution then. Here’s another example of running Pass Arrays, followed by Point Data to Cell Data inside a Programmable Filter run PassArrays and PointDataToCellData filters to get element variables faster run on entire MultiBlockDataSet use pass arrays to extract arrays of interest myArraysvtk.vtkPassArrays() myArrays.SetInputDataObject(self.GetOutputDataObject(0)) myArrays.SetInputDataObject(self.Animate polydata using programmable filter is close but the author takes a constant multiplied by the time in transform.RotateY(-5*t) and I would like see something like TableToPoints.PointData The transform filter through a python script is probably the way to go but I am at a loss how to reference the TableToPoin inputs.

* si I guess this is not the right method. The python calculator requires that both datasets are equal if I want to use the input.* and input. how to reference the TableToPoints inputs in the transformation of the cow.I convert the csv files to points (TableToPoints) and I am trying to use them as input for a filter to translate and rotate my geometry (cow). I have a geometry file (think of the VTK cow for example) and a time series of csv files with the new centre of gravity and orientation angles. This topic appears quite often in the archives but I was not able to figure out how to do this, perhaps because I’m a total vtk/python noob.
