It should be pretty easy to define quadrilaterals or triangles that connect the points. Although not square, your domain is fairly simple. You can do that by making selections in the 3D window and then extracting the selection.Īnother option is to write out your data in a different format that captures the mesh you want to represent. Second, you will have to manually remove the "extraneous" polygons generated outside of the domain. This is probably most easily done by editing your input. First, you will need to offset the points on that shelf in the x direction so that they do not have the same (x,y) coordinate. To get this to work with Delauny 2D, you will need to make some corrections. This is especially useful for people, using older plugin's that can not use grids with the VTKVOXEL type. Any points with the same (x,y) coordinates will be treated the same. The key difference to ParaView's Clean To Grid is that instead of generating VTKVOXEL cell types, Transform Grid provides the cell type VTKHEXAHEDRON. As the name implies, Delaunay 2D projects all the points to the x-y plane and does a 2D Delaunay triangulation. I assume this is supposed to form a vertical shelf, but instead Delaunay 2D is ignoring some of them because they have the same (x,y) coordinates. It looks like there are 3 pairs of points that share (x,y) coordinates. I notice another issue with your data and Delaunay 2D. Like it or not, I don't think anyone knows a more robust way to determine the bounds of a region when given nothing but a set of points. So the Delaunay 2D filter makes the simple assumption that the region is supposed to be convex and fills in those regions. The Delaunay 2D has no way to know whether those non-convex regions (those empty regions from about -15 to 2 along the X axis) are supposed to be part of the domain or not. The domain you are trying to display is non-convex. The input file is (.csv file): "x", "y", "z" In the link above, it can be used easily since the domain is a rectangular. I have also tried it unfortunately, since my domain is not a rectangular, there were some useless triangulars which were formed outside main domain. Displaying an Elevation grid in ParaView). I have also read some previous articles that the best way is possibly to apply a filter "Alphabetical -> Delaunay 2D" (e.g. I am a new comer in Paraview and would like to ask how I can make a 3D view of a reservoir. Hi craigmillernz, I'm glad to see that you figured this out on your ownTo be thorough, I thought I'd add a bit more details on texture mapping for a GeoTIFF on a topography surface - also, I do this ALOT so I have plenty of examples.
