(Posting this back to the mailing list. I didn't realize we left it.) Once again assuming I understand your problem (and I'm not sure I totally do), you have a large surface area of land that is much much larger than any change in surface elevation. Thus, you cannot see the change in depth and everything looks like it is a plane (or slightly curved surface depending on how you transform it).
This is a pretty common problem in visualizing ocean, atmosphere, and similar geographical topics. The distance from the deepest ocean trenches to the peak of the tallest mountains is tiny compared to the area of the surface. To see anything of interest, you will probably have to stretch the geometry radially. -Ken From: Léo Pessanha <[email protected]<mailto:[email protected]>> Date: Monday, September 16, 2013 3:48 PM To: Kenneth Moreland <[email protected]<mailto:[email protected]>> Subject: [EXTERNAL] Re: [Paraview] Points Movements - Kilometrical extension x metrical movement I guess the physical [x,y,z] coordinates of the shore geometry should be interpreted as [latitude (degrees), longitude (degrees), elevation (kilometers)]. I suppose the trajectory positions would be stored as [latitude (degrees), longitude (degrees), elevation (meters)]. If that is the case, just do a transform with scale values of [1,1,1000]. THAT'S 100% CORRECT. I already did that 1,1,1000 when i transform the data from .dat to .txt It`s everything in the place where it should be. The thing now, is that the shore extension go to -30 to -16 degrees ( a lot of kilometers, i heard that 1 degree its like 110 km) The trajectories while under the earth level have a side dislocation too small compared to the extension of the shore, because of that i can only see a line going up, not moving right/left. I think the paraview precision is causing it so i dont think(maybe i can, but dont know how, thats why i am asking) i can do too much with paraview but in the other hand, i can do something with the data, so it will at least give me an idea of an curvature in one of my tries i rescale all the data by 1000, ^2, but i just get the same thing with diferent numbers i am ploting points over time(lot of ****1.csv, ****2.csv,.....) 2013/9/16 Moreland, Kenneth <[email protected]<mailto:[email protected]>> I guess I don't really understand your problem. Latitude and longitude are of course in degrees or some other angular measurement, not meters or kilometers. Presumably the latitude and longitude have the same units for the shore and the trajectories or you would have said something about that. So I'm going to start guessing to fill in the details. I guess the physical [x,y,z] coordinates of the shore geometry should be interpreted as [latitude (degrees), longitude (degrees), elevation (kilometers)]. I suppose the trajectory positions would be stored as [latitude (degrees), longitude (degrees), elevation (meters)]. If that is the case, just do a transform with scale values of [1,1,1000]. Or maybe there is more to it than that. You mentioned something about dislocations. Perhaps you mean displacements, but displacements of what? Or maybe the trajectories/displacements are in Cartesian coordinates instead of lat-lon spherical coordinates. In that case, you must be doing something to convert between the two, which I would think rescaling from meters to kilometers could happen then. Anyway, without more information I don't think I can help. -Ken From: Léo Pessanha <[email protected]<mailto:[email protected]>> Date: Monday, September 16, 2013 2:30 PM To: Kenneth Moreland <[email protected]<mailto:[email protected]>> Subject: [EXTERNAL] Re: [Paraview] Points Movements - Kilometrical extension x metrical movement It`s not that simple The position is given by Latitude(x) and Longitude(y) If i just scale the values, i have to do in both fields, and then i just get the same representation with bigger values I think it will only be possible to see something that look like a curvature if i do something mathematicly with the distance between consecutive points, but i dont know waht to do 2013/9/16 Moreland, Kenneth <[email protected]<mailto:[email protected]>> You can use the calculator filter to scale the values in a field. You can also use the transform filter to scale the physical positions. -Ken From: Léo Pessanha <[email protected]<mailto:[email protected]>> Date: Monday, September 16, 2013 1:13 PM To: "[email protected]<mailto:[email protected]>" <[email protected]<mailto:[email protected]>> Subject: [EXTERNAL] [Paraview] Points Movements - Kilometrical extension x metrical movement Hi I have a represented bathymetry of a shore, and inside of it there's fluid trajectories. The problem is, the bathymetry have a extension of kilometers and the trajectories side deslocations happens in meters, so its like a straight up line, i cant see the curvatures Can someone give a tip of how can i interpolate the data so i can see curvatures, or a way to rescale my lateral axis or something like that, like the precision of the data or the precision of paraview Att, Leonardo Pessanha Rio de Janeiro, Brasil
