Hi Stefan If I am not wrong just try this one.Set the spatial Scalarmaps (one that involve Display.XAxis and Display.YAxis) to the data range that you are interested in and then set the clip with -1.0 to 1.0. It should work. Pretty crude solution but I think it should work if you the spatial scalar maps are pretty linear.
Otherwise there is a longer way to do the same thing. I hope I am clear in communicating. regards Ghansham On 01/22/2014 12:30 AM, visad-request@xxxxxxxxxxxxxxxx wrote:

Check flatfield.resample() method. The flatfield that you extract from fieldimpl, you can call this method for that flatfield. This method take the domainSet of the target field. regards Ghansham On 01/21/2014 12:30 AM, visad-request@xxxxxxxxxxxxxxxx wrote:Send visad mailing list submissions to visad@xxxxxxxxxxxxxxxx To subscribe or unsubscribe via the World Wide Web, visit http://mailman.unidata.ucar.edu/mailman/listinfo/visad or, via email, send a message with subject or body 'help' to visad-request@xxxxxxxxxxxxxxxx You can reach the person managing the list at visad-owner@xxxxxxxxxxxxxxxx When replying, please edit your Subject line so it is more specific than "Re: Contents of visad digest..."

So i have to iterate over all sequence and check if there is a point near my coordinate. After that, i have to check which result is the nearest, right? Or is there a better solution? I try to clarify my question: 1b) convet a flat field with the the mathtype (time->(lat,lon)->temperature) to (lat,lon)->temperature (convert the data to a linear grid) 2) How can i calculate the clipping parameter? I need a user defined clipping area. So how can i calculate from an axis value (like x=70) to the clipping parameter X_POS and/or X_NEG? dr.setClip(0, true, 1.0f, 0.0f, 0.0f, -1.01f); // X_POS face dr.setClip(1, true, -1.0f, 0.0f, 0.0f, -1.01f); // X_NEG face Thanks a lot, Stefan Below On 18.01.2014 10:29, Ghansham Sangar wrote:Hi Stefan Regarding point 1, the visad data object corresponding to the function type that you mentioned is a FieldImpl.

(The result should be a n x m grid with temperature values. b) I want to get the value information for a specific coordinate (in this case lat/lon). field.evaluate(LatLonRealtupleType) is not working, because of the wrong mathtype. 2) I'am using screenbased axis with TwoDDisplayRendererJ3D . Now i want to set the clipping area to the bounds of the screen based axis. But i have no clue how to calculate the clipping area. For testing, i tried to use the cursor position as a clipping boundary. double[] cursor = getCursor(); float tmpXMAX=(float)cursor[0]; tmpXMAX=1-(tmpXMAX-1); setClip(0, true, tmpXMAX, 0.0f, 0.0f, -1.0f); But it is not working as aspected. The boundary is only correct if the cursor is exactly over the right side of the box (cursor position = 1). I think i missed some kind of transformation. Maybe someone can give me a hint.

There are also methods to transform to/from screen and display coordinates. Tom On 1/21/14 4:02 AM, Ghansham Sangar wrote:Hi Stefan There is a better solution... Check flatfield.resample() method.

The transformation between display and data coordinates is clear and works fine. But if i use the display coordinates for DisplayRendererJ3D.setClip(int plane, boolean enable, float a, float b, float c, float d) method, it does not work like expected. Its not "clipping" on the given display coordinate. (Only clipping on the visad cube for display ccordinates -1.0 to +1.0f is working like expected).
