Conversion to uniform grid
Hi everyone,
I have 2D data (in .VTK files) in a quadtree structure. However, i need this data to be converted to a 2D uniform grid, in a way that i can e.g. specify the extent in X and Y direction and my quadtree gets resampled respectively. Does anyone have an idea how this works with paraview? Best, Gebhard |
I managed to find a (partial) solution to my problem.
To get my data into a uniform grid I do the following: 1) apply 2D delaunay (otherwise the resampled data will contain holes) 2) add a plane as a source with N*M sample points 3) Resample with data set (using the plane as source) This works pretty well. However, for writing my data to a file in the way I need them, it seems that I'll have to implement my own writer for paraview. Does anyone have some experience with that or is there a best practice how to do this? Best, Gebhard |
Greetings Gebhard and welcome to the forum!
Without a small test case, I can't test this myself. One question that comes to mind: Is the data you've got from the "quadtree structure", does it already look like a uniform mesh? The only suggestion that comes to mind is to use the filter "Triangle Strips", which will sort the triangles from Delaunay 2D into a more efficient order of triangles. Best regards, Bruno |
