• Points of intersection of the lines

  Hi guys, I have a little problem. I have two sets of points, which sets two rectangles. I need to know what area they share. No idea how to do?

  

  I found "Polygon Area.vi" function. but I need points of intersection of these two rectangles to compute the inner area for this function.

  Thanks for any advice.

  I just did a quick check and did not see the convex polygon in LV 2011 VI of Intersection.

  It shouldn't be too hard to write your own.  You need to consider several possible cases: polygons do not intersect.  Polygons have exactly one thing in common (one is on an edge or one vertex on the other). Polygons have in common the segments in one or more edges. A polygon is completely contianied in the other. And if you showed polygons overlap but do not share an edge or a vertex.  If the polygons can be concave, additional complexity might be involved.

  Some simple analytic geometry will allow you to locate the intersection of two straight lines formed by the edges of the polygons. You must then determine if the intersections are on the edge or outside the polygon. Once you have found the 4 (or zero) points of intersection which are relevant, you can use the Poylgon Area.vi, which is in LV 2011, to calculate the desired area.

  Since you're using the student Edition, this is a school assignment?  If so, most of the participants on the Forums will not do your work for you because you don't learn something like that, but we'll help you learn LV

  The steps I would take are: 1. define the case of polygons possible in your situation. 2 analytical hand geometry to make you understand the issues. 3. set the program, with possibly a flow chart or a diagram of the State, with regard to points 1 and 2. 4. write code to implement 3 LabVIEW.

• How can I find several intersect between the number of lines

  Hello
  
  I created the table as below,
  
  CREATE TABLE "TRANS" (NUMBER (9.0) "TIDSET", "ITEM" NUMBER (9.0)); "."
  
  and insert valuse Trans table as below,
  
  insert into values trans (1,1) insert into values trans (1,3) insert into values trans (1.4); insert into values of trans (1.5); insert into trans values (1.6);
  insert into values trans (2.1); insert into values trans (2.2); insert into values trans (2, 4); insert into values trans (2,6), trans insert values (3,1);
  insert into values trans (3,2) insert into values trans (3.3) insert into values trans (3.6); insert into values trans (1, 2); insert into trans values (1,1);
  
  and now I have to find the intersection between the lines as below,
  
  Select tidset from whose point trans = 1
  intersect
  Select tidset in the point transwhere = 2
  intersect
  Select tidset from trans whose point = 3;
  
  If we have 1000 lines there is no way to find the intersect in this way, so I need to write a program to find the intersect as above without inserting the (item = N) manually each time, can you help me with this please?
  
  Thank you

  This is not true. The query you posted will work well for any number of lines. Perhaps you are really worried about the number of distinct values of the point.

  so I need to write a program to find the intersect as above without inserting the (item = N) manually each time, can you help me with this please?

  In a solution of Ivan, you probably mean "COUNT (DISTINCT point)" rather than "COUNT (*).
  In addition, if element values are predictable, you don't have to code in all hard; You can generate, like this:

  SELECT       tidset
  FROM       trans
  WHERE       item      IN (
                 SELECT     LEVEL
                 FROM     dual
                 CONNECT BY     LEVEL <= n
               )
  GROUP BY  tidset
  HAVING       COUNT (DISTINCT item)     = n
  ;
  

• How to find a point of intersection between two paths in the hierarchy? (2 G 11)

  Hi all!

  I need your help to write a hierarchical query.

  Suppose that we have a table hierarchycal as

  WITH h AS (SELECT 0 AS rn, to_number(NULL) AS prn, 'root' AS point_name   FROM dual
  UNION SELECT 1 AS rn, 0 AS prn, 'a' AS point_name  FROM dual
  UNION SELECT 2 AS rn, 1 AS prn, 'b' AS point_name  FROM dual
  UNION SELECT 3 AS rn, 1 AS prn, 'c' AS point_name  FROM dual
  UNION SELECT 4 AS rn, 2 AS prn, 'd' AS point_name  FROM dual
  UNION SELECT 5 AS rn, 3 AS prn, 'e' AS point_name  FROM dual
  UNION SELECT 6 AS rn, 2 AS prn, 'f' AS point_name  FROM dual
  UNION SELECT 7 AS rn, 3 AS prn, 'g' AS point_name  FROM dual
  UNION SELECT 8 AS rn, 6 AS prn, 'h' AS point_name  FROM dual
  UNION SELECT 9 AS rn, 5 AS prn, 'i' AS point_name  FROM dual
  UNION SELECT 10 AS rn, 7 AS prn, 'j' AS point_name  FROM dual
  UNION SELECT 11 AS rn, 10 AS prn, 'k' AS point_name  FROM dual)
  SELECT h.* 
  FROM h 
  CONNECT BY PRIOR h.rn=h.prn
  START WITH h.prn IS NULL
  

  I chose a single line, with rn = 11 for example, as a "starting point." After that I need to select one or more rows in this table under certain conditions. Whether rn = 8 and 9, for example. By the same query, to the next step, for each point that I chose by condition, I need to calculate, how far is it to the "starting point".

  I think, I need to find a point of intersection of the path from the root to the selected point along the same path of the "starting point". By comparing this tip I'll can understand which of them is closer to the "start".

  The only thing that I have arrived, it's trying to compare the results of sys_connect_by_path...

  Hello

  This indicates to what extent each of the nodes 'interest' are from the node of "start":

  WITH connect_by_results AS

  (

  SELECT CONNECT_BY_ROOT rn: the NURSE

  CONNECT_BY_ROOT SUBSTR (point_name,

  1

  8

  ) AS node_type

  rn AS ancestor

  LEVEL AS lvl

  H

  START WITH point_name = 'start '.

  OR point_name LIKE '% interest '.

  Rn = prn PRIOR CONNECTION

  )

  SELECT i.rn

  , MIN (i.lvl + s.lvl) - 2 AS distance

  Connect_by_results I have

  JOIN connect_by_results s ON s.ancestor = i.ancestor

  WHERE s.node_type = 'start '.

  AND i.node_type = 'interest '.

  GROUP BY i.rn

  ORDER BY i.rn

  ;

  Exit: (from your sample data, where 11 is the starting node):

  DISTANCE OF RN

  ---- --------

• angles between the lines

  I am trying to find a way to understand the angle between the lines. These lines will always intersect. For example, if a line has xy of 100.0 and 100 200 values and the other line has a value of 0.50 xy and 200.50. These two lines when Wescott on a graph are 90 degrees to each other. I can just find a way to do this. Any ideas?

  Here's a way to do it. You can also use the mathematical functions to make it as Lynn suggested.

• How do you multiline text in a continuous form between the lines without scaling of the text?

  Help. How do you multiline text in a continuous form between the lines without scaling of the text?

  I tried to put each line of the form for amounts of specificity so that it ends at some point and does not change the text size to fit on the line but different key characters have different widths, so you do not get a length of the same line.

  I tried to remove the long text scrolling, but it changed nothing.

  I can create a text box great to fill out and have this scrolling of additional lines, but then I get too much information from people and I would need to clarify the lines behind the answer multi line text, or delete the lines...

  Is there a better solution?

  I usually just remove the lines and set the field "Does not scroll long text" so that all the text is visible. Including the lines is really only useful if the form may be printed and completed by hand, in which case you can use scripts as in this example is: http://acroscript.net/pdf/demos/multiLine_Demo1.pdf

  It works as expected in Acrobat/Reader, but not in Chrome and other PDF viewers who have little or no support for JavaScript. It uses scripts customized to validate on Focus and blur.

• How to find the point of intersection of the two geometry?

  Hello
  Could someone give some suggestions on how to find the point of intersection of the two geometry?
  I need just point. (x, y, z)
  Thank you

  Can you post the full result of geometry returned?

  What you should have as a result:

  MDSYS. SDO_GEOMETRY (2001, 1, NULL, MDSYS.) SDO_ELEM_INFO_ARRAY (1,1,1), MDSYS. SDO_ORDINATE_ARRAY (2.0,2.0))

  Notice the sdo_intersection will use only the sdo_ordinate_array, even if the result is a point! (with the SDO_POINT is NULL.)

  where do you find these x, y, z values of?

  On your other question:

  -using the operator space sdo_relate (with mask = ANYINTERACT) will return in pairs, the result of the intersection of each anyinteracting polygon, line combination.

  -of course, these results will vary from point, multipoint, line or multiline even depending on how the interaction takes place.

  -try to explain a bit more what do you mean 'I want only points to return' of nit.

• Code view in Dreamweaver displays large empty spaces between the lines

  See attached image. Code view shows large differences between the lines. It is not an extra space. I can't remove it. As you can see in the picture if I select the code space is attached to the code. I'm sure that it is a very simple display option change, but I've looked everywhere. I've just upgraded to the latest version of the thought of DW which may help, but he always does. How can I get rid of the extra space?

  

  With highlighting the way in which it is, it seems to me that you may have a corrupt police.

  Go in Edition > Preferences > fonts > mode Code and switch to Source Code Pro (if this isn't the case) or something like courier so it is.

• How to get the points of contact between the points and polygons

  Hi ~
  
  I am
  work based on Oracle 11 g and
  looking for a way to get points of contact between the points and polygons.
  
  For example, I have two data STORE (point) "and"(polygon) ROAD"and each store must have a contact point or points of contact for the nearest road.
  
  I know what the closest route is using SDO_NN, but I don't know hot to get the point of contact.
  
  Please let me know hot to do ~
  
  Thank you.

  If you have the point and its nearest road, you can find the contact point (ie the store point nearest the road linestring) using SDO_LRS function Project_Pt as follows:

  With route As (
    select SDO_GEOMETRY(3302,NULL,NULL,SDO_ELEM_INFO_ARRAY(1,2,1),SDO_ORDINATE_ARRAY(2.0,2.0,0.0, 2.0,4.0,3.218, 8.0,4.0,12.872, 12.0,4.0,19.308, 12.0,10.0,28.962, 8.0,10.0,35.398, 5.0,14.0,43.443)) as route,
           SDO_GEOMETRY(2001,NULL,sdo_point_type(9,3,NULL),null,null) as store
    from dual
    )
    SELECT SDO_LRS.PROJECT_PT(route, store) as store_on_route
    FROM route ;
  -- Result
  --
  STORE_ON_ROUTE
  --------------------------------------------------------------------------------------------------------
  MDSYS.SDO_GEOMETRY(3301,NULL,NULL,MDSYS.SDO_ELEM_INFO_ARRAY(1,1,1),MDSYS.SDO_ORDINATE_ARRAY(9,4,14.481))
  

  If you don't have a space licence, try using my LRS for users of Locator at: http://www.spatialdbadvisor.com/source_code/214/linear-package-sdo_lrs-replacement

  If this is correct, please give points. (I work for love IE Points not money!)

• Insert a line between the lines

  Is it possible to add a line between the lines?

  Hello Vic,

  Yes it is.

  Place a button on your table and add the following to its click event Javascript code:

  var currentRepeatable = this.parent;
  var im = currentRepeatable.instanceManager;
  var newRepeatable = im.addInstance(1);
  im.moveInstance(newRepeatable.index, this.parent.index);
  

  You may have to replace "this.parent" in line 1 by another SOM-Expression refers to your repeatable line containing your button.

  Currently, the new instance is inserted before the line containing the button. If you want to insert, after the change of current line, the last line:

  im.moveInstance(newRepeatable.index, this.parent.index + 1);
  

  Hope that helps,

  Martin
