FIRST HP: GEOMETRY
Why the GEOMETRY application draws derived for example. The function x ^ 2-x ^ 3, sine, cosine and does not scratch the functions derived as the tangent, logx, LNX. Draw an incomplete derivative of graph of y = 1 / x. Why is it like that.

FIRST HP: Geometry commands Tests
Hello
In the application, we function TEST of GEOMETRY. It is a unique but very necessary function. Let me give you an example. I draw the GD rectangle, rectangle (GA, GB, GC). Then, in the geometry view digital and I write is_parallelogram (GD). Then back to the Plot of the geometry window and enter for a vertex to change its dimensions (length and width). Nevertheless, always on the screen I have a rectangle. But on the screen TEST shows strange things. Once the is_parallelogram (GD): 1 then is_parallelogram (GD): 3. even for other geometric figures:
Rhombus, square, triangle, isosceles triangle.
Ill work TEST function in the construction of their own this building, where there are forms of a rectangle, square, diamond or different triangles. When we change the dynamic side of these figures we get messages wrong: is_parallelogram, is_ isosceles, equilateral is_.
I use a lot of GEOMETRY and these false messages on the screen annoyed me. It works great the TEST function for the parallelogram of figures. It shows always, at any time, without any error is_parallelogram (GD): 1. it is similar to is_collinear (). OK, but not perfectly with the command is_parallel and is_perpendicular. It must also be corrected to make it without reservation. I have another question. Is the is_element () command is the mathematical functions only or for different geometric figures and geometric constructions.Best regards!
Johnder
Hello
I'm not sure I understand your question exacly (English is not my native language), but I'll try to bring some light it...
The is_parallelogram function can return the numbers 0, 1, 2, 3 or 4 to indicate: no parallelogram, parallelogram, Rhombus, rectangle and square.
Go back 0 or 1 that you complain?
In the application of geometry tests are performed on the values of the coordinates of the object floating points. Unfortunately, this leads to loss of precision which in turn throw off-label test (the value of floating points being the accupressure, the figure is only approximately parallel or rectangle). Perhaps what you are experiencing.
If this is the case, an easy solution is to change the setting of case epsilon.
To compare 2 numbers, system of computer algebra (which is the calculation behind the application of geometry engine), subtract them and test if the result is smaller (in absolute value) to epsilon. Change the default 1e-12 1e-10 Epsilon (in CASE settings, page 2: update, Page Down).
This fix works because, to test if 2 lines are parallel, the CASE will calcualte their relative angle and then compare that angle with 0 (or 90 to perpendicular). Which will make the more lenient number comparison will make the geometry to test also more linient.
I hope this helps.
Kind regards

HP first app - a problem of circle geometry
Here's a problem for a graphical solution for (using the Geometery application):
Given a unit circle, finding another circle that is framed by the axii unit circle and x and y.
I tried to use the features in the application, but either I could not find the means to compel the circle (as with the two tangents and circle) or through indirect and mistakes means (on the resolution of the crossroads, etc.). I thought I had it almost with the following definitions is entered in the symbolic view:
I actually had to cheat and understand I and J with Algebra first here then place exactly (since I can't force things as I want)
However, when I draw it, the GK circle is not visible! (?), as shown below
The new circle must have been touching points H, I and J.
I also tried to generate a horizontal line at point I using plotfunc (computer (GI)) and trying to intersect with x = line is but the calculator gave a bunc of errors.
I found the Geo. App. a bit tempramental. It seems that many times I have to find just the right way to get things to work (if that is the case). Usually by then it would have been quicker to do it by hand on graph paper.
Anyway, why no smaller circle of the solution and how could I have do more easily in the application?
It worked, thanks!
I guess it was confused (which I don't think it should have been) on the double intersection of the line and the circle.
I of course didn't know this third option with inter () - this isn't in the help!

Set of geometry invoke node: do not have this method (and why is it red?)
Hi all
So I take my first steps with the 3D picture control, and I stumbled over the first hurdle!
How to create a 'set of geometry' call, node, as shown in this photo? If I have the wiring in the output of the object to create an invoke node I get a standard invoke node with several options, but none related to the geometry.
Second question: why is the Red node to invoke?
Finally found the reason:
alignment has been deprecated in LV8.5, from the help:
Obsolete properties, methods, and events
LabVIEW 8.5 does not support the properties, methods and events:
- Property of the geometry of the SceneObject class. Use the Drawable property instead.

I recently copied my default system hard disk (320 GB / Western Digital) on a larger hard drive (500 GB / Hitachi) which I also ordered through Lenovo.
Using a disk imager I first copied the old 1:1 the new disk drive. It gave me an exact copy of my original disk, with about 150 GB of space disk unallocated at the end of the training. I then put this copy in the system and it worked very well, I could start and work at it.
-With the help of Acronis Disk Director 11 - I moved the hidden partition Lenovo restore to the end of the new drive, and then finally I expanded the system partition to fill all the available space before this recovery partition, giving me a system about 430 GB drive.
These operation seemed to go very well at everything first, but in the end I got an alert that something had gone wrong and now the disk may be corrupted. Strange, I was able to boot from the disk and everything went well in the beginning but in fact - I now have a very weird problem: when you look in the Panel-online-online disk management management system all partitions are located and that I had the intention of size. The recovery partition (~ 17 GB) is at the end and the system partition is indicated as approximately 430GB and about 60% vacuum. Explorer Windows, however, always reports the size of the old partition (~ 280 GB) and only 10% of empty space, while if there is no resizing the partition space taken.
In other words: different parts of Windows 'see' and report to different partition sizes. Running chkdsk does not resolve the issue.
I then realized this phenomenon in the Acronis Disk Director forum and some guys Acronis replied, that problems of resizing and therefore also the difference could be due to the fact that IBM/Lenovo uses a geometry to non-standard head of 240 heads instead of 255 heads. ???? I then asked for details and - if possible - instructions - how we could solve this problem, but got no further response so far.
Any idea what he's talking about? Lenovo indeed uses some non-standard disk or geometry? I would have thought, that the access disk is the disk drivers? Lenovo have to do here? Or BIOS of the device involved here?
And finally: has anyone some experience with this problem and can give an idea how to solve this problem? I'd really like to * hate * restart everywhere have to reformat the hard drive and reinstall everything again!
Michael
Thanks for this info!
I'll try to get my wrecked HD using the Paragon suggested partitioning program and I guess, I'll also try to get a refund on DiskDirector 11, since the site explicitly, it is fully ready Windows7, which obviously isn't!

How gaps (fill) when converting to a 2006 geometry in a geometry of 2002
Is it possible to fill (filling) the differences when converting to a geometry in a single geometry of 2002 in 2006. I have a solution for the conversion of 2006 to 2002 provided by BHall but on other investigation of my dataset some of the multi line polygons are weak I need to fill and I don't know how to go on this subject.
Here is a simple example of what I'm trying to reach
Front
SELECT (sdo_geometry (2006, 81989, NULL,))
MDSYS.sdo_elem_info_array (1,2,1,5,2,1,9,2,1,13,2,1),
MDSYS.sdo_ordinate_array (16,0.999,16.998,-0,001, 17.253,-0.001, 18.003, 0.999, 18.003, 0.999, 19.001, 0.999, 19.001, 0.999, 19,999,-0,001)))
OF the double
After
SELECT (sdo_geometry (2006, 81989, NULL,))
MDSYS.sdo_elem_info_array (1,2,1),
MDSYS.sdo_ordinate_array (16,0.999,17.253,-0.001,18.003,0.999,19.001,0.999,19.999,-0.001))) DOUBLE
Thanks in advance
Hi rock,
Well, I ran all three examples that you sent through my code and it seemed to work! I pasted the code above in a "pre" html tag and I can still see things deteriorated. Lemme try this with a different syntax. You know that this new forum software not only grew on me. It's just clumsy and exaggerated. And those weird people at the top. What were they looking at? I imagine that Larry on some loft above.
Anyway, you are right that when Bryan code is used to convert the multiple string, the gaps are filled. But that's because he wrote of this approach.
Really, there is no generic way to convert a multiple line string we are discussing. If you use SDO_UTIL. CONCATENATE_LINES, it will leave gaps.
See you soon,.
Paul

get all the vertices of a geometry of polygons
I tried to use sdo_util. GetVertices to retrieve all vertices of a geometry column. Some of the geometry of gType 2007 which contains several elements. GetVertices function seems to give the vertices of the first item only. How can I get all vertices then?

How can I remove inner rings of a complex geometry of type SDO_GEOMETRY
Hi all
I'm looking for a better way to remove the inner rings of a complex geometry of SDO_GEOMETRY using ORACLE packages. I have a complex geometry, called MAINGEOM, which is to have two elements of disjoint ELEM1, ELEM2, and each item will have a ring of hole/inner completely inside the ELEM1 and ELEM2 respectively.
I wanted to just delete the two rings of holes / inner of each ELEMs.
Initially, I planned to collect all the individual rings that are not inside the element using SDO_UTIL. EXTRACT and collect them in a collection, and subsequently all adding them to the first element of the collection to prepare a new geometry.
FOR rec in c1
LOOP
new_g: = SDO_UTIL. APPEND (new_g, rec. GEOM);
END LOOP;
I feel, this average gross to solve the problem. I doubt that there should be an existing SDO packages to remove the rings/items inside/required.
Can you please help me solve this problem anyone and let me know if more information is needed.
Kind regards
KumarKumar,
As I said in my post, if you extract (idx, 1), you will always get the outer ring, so you don't need to worry about the holes that you will ever extract them.Siva

Error during processing of a geometry of buffering
It makes me crazy!
I have a procedure that compares a standard polygon to other polygons which is held in a number of tables to see if they interact. Some of the geometry that is held in the other tables are of different systems of coordinates, so before I compare I translate the geoms. It all works very well.
However, if I have the geometry buffer before calling the procedure, I get all sorts of errors to do with transformation. No matter who successfully translated polygons in the buffer? and if so, how
Thank you very much
Chris

OF THE DOUBLESDO buffer usually generate arcs in the result (etype = 1005) for projected coordinate systems. If you use the geometry of the buffer in sdo_cs.transform, you might encounter problems.
You can use SDO_GEOM. Funtion SDO_ARC_DENSIFY before turning them in geodetic coordinates, and then perform spatial operations on geometries that result.6.2.5 Other Considerations and Requirements with Geodetic Data (11.2) The following geometries are not permitted if a geodetic coordinate system is used or if any transformation is being performed (even if the transformation is from one projected coordinate system to another projected coordinate system): * Circles * Circular arcs Geodetic coordinate system support is provided only for geometries that consist of points or geodesics (lines on the ellipsoid). If you have geometries containing circles or circular arcs in a projected coordinate system, you can densify them using the SDO_GEOM.SDO_ARC_DENSIFY function (documented in Chapter 24) before transforming them to geodetic coordinates, and then perform Spatial operations on the resulting geometries.Or you can try everything first to transform the geometry and then generate the buffer and then issue your sql queries.

Strange problem (bug?) with access to a specific geometry
We have a database with hundreds of thousands of polygons (among others).
We have a number of queries that retrieve polygons in a (rectangular) area chosen by the user.
In general, everything works fine.
However, in trying to retrieve data of a particular area, we found that oracle kept throwing at the end of the file (03113)
or 'no more to read shooting Data' exception and disconnection.
Our first was that the region contained too many data [we often get this exception when you try to return large amounts of data, but it's another
question]. But no, we could limit the area such that it contained only a handful of polygons and he always threw the exception.
After more testing, we were able to narrow the problem down to a single geometry.
It validates ok, and geo raptor in sql Developer, it can display ok (it is a torus lying, somewhat like a race track).
However, do not attempts to run the query on the matter.
We have reduced the query as follows:
INSERT INTO RDTESTIDS
SELECT RDTestTA.Polygon
OF RDTestTA, RDTestPoly
WHERE RDTestTA.Polygon = RDTestPoly.ID
AND (SDO_ANYINTERACT)
RDTestPoly.geometry,
SDO_GEOMETRY (2003, NULL, NULL,)
SDO_elem_info_array (1,1003,3),
SDO_ordinate_array (531250,163965,531310,164000)
)
) = "TRUE";
Where:
RDTestTA is an array that contains two fields: TAID (NUMBER) and POLYGON (NUMBER)
RDTestPoly is an array that contains two fields: ID (NUMBER) and GEOMETRY (SDO_GEOMETRY)
RDTestIDs is a table containing the unique field: ID (NUMBER)
Success of this operation for each geometry, we met so far except the 'circuit '.
and we do not know what could be the cause of the problem.
Curiously, if we remove the "INSERT INTO RDTestIDs" or joining with RDTestTA, it works!
Suggestions of the ad hoc to avoid the problem by rewriting etc. are not really what is needed here
-He should know what he is this geometry that is causing Oracle to fail
where it occurs with other geometries and/or queries we encounter in the future.
Any help to fix this would be greatly appreciated.

However, in trying to retrieve data of a particular area, we found Oracle kept throwing the exception of 'No more to read shooting Data' or end of file (03113) and disconnect.
In other words, the dreaded ORA-03113 error.
So, I'm afraid that I can't test your problem on 10.2.0.1.
But I can confirm, as Luc, it works on 10.2.0.2 Patch 18 on Windows XP.
I would recommend you get down the relevant updated version + its patches for your operating system from Metalink.

SDO_GEOM. VALIDATE_GEOMETRY_WITH_CONTEXT for the validation of the polygon geometry
Hello
I have a validation of the geometry of the polygon on a table SCHEMA. TABLE with the GEOM field, where the geometry is stored.
Can someone help me with an example SQL sentence to fill my SCHEMA. Table with all the errors that occurred in the SCHEMA VALIDITY. TABLE?
Thank you!
DejanHello
-First create your table schema.validity
create table schema.validity (ID number, varchar2 (200)) of validity;
-Insert values into it
insert into schema.validity (id, validity) select id, sdo_geom.validate_geometry_with_context (geom, 0,000005) from schema.table;
-Updated the values inside
updated schema.validity an a.validity = set (select sdo_geom.validate_geometry_with_context (b.geometry, 0,000005) in schema.table b where a.id = b.id);
-Remove the real case of table schema.validity
delete from schema.validity where a.validity = 'TRUE';Hope this helps

Preview.app stuck on the first page of the PDF in single page mode
I regularly Preview.app view PDF files and want to use the "Single Page" function to display an entire page at one time. I have 'Single Page' display set as the default behavior.
Lately when I open a PDF file, they properly open the first page, but I am unable to navigate to another page via the drop-down page, touch up/down arrow. If the PDF file has a table of contents, I am able to go beyond the first page through it and then proceed to navigate normally. If it is not a table of contents, the only solution is to continuous scrolling mode and continue to navigate beyond the first page.
It's very annoying! Unfortunately, I can't remember where this started happening. It could be when I upgraded to MacOS Sierra, but I can't confirm.
Everyone else see this behavior?
Hold down the Option/ALT key, then use the cursor to the TOP or to the BOTTOM of the key.

Date page does not appear first drop the bar down
Just downloaded the new ios and found that the Notification Center page appears first when you use the new bar drop down. I have to keep pulling down then drag to the right to display date apps, weather, news, etc.
How can I configure it so that I can view the main page widget first, when you pull down the drop to the low bar and not the notification page?
Thank you!
Just drag to the right at the beginning. No need to blow first.
