3d problem - drawing order
Okay, I'm working on 3D stuff and everything is going fine, etc. But I've got one problem: I don't know how to determine the drawing order of all the faces, so know faces behave like they shouldn't, because they get drawn at the wrong order, and get drawn while they actually shouldn't be. I'm NOT using Java3D.
Currently, I'm using the painter's algorithm (get the distance of the face to the center, and determine the order that way), but it's not working properly, as expected. I read BSP-trees are the best way to determine the order of the drawings, but I can't find any decent BSP-tutorial (for 3D) nor any code I can use.
My question: Does anyone knows a decent, detailed 3D-BSP-Tutorial, or any code I can use/examine or could anyone explain it here or tell me an other (easier) method. It should be a fast method, because I'm using this for a game I'm creating.
Please help,
Matt.
Matt, could you be a little more specific? Like what is exactly your polygon drawing problem? Some of the polygons are inside out, or all of them? Or they render in very wrong locations etc?

problem with order in iPhoto. I can't buy a card, because there comes an Message "Ihre Karte enthält offenbar Standardtext, der noch nicht bearbeitet wurde. Gedruckte Karten enthalten diesen Text nicht. Möchten Sie fortfahren?" What should I do?
That message means that you have text boxes that have not been used. The holding text that appears in the box will not be printed. But if you want to get rid of the warning just put a space in the text box.
OR, check to see if the card layout has the same page but without a text box. Most do.

Problems submitting order via iphoto
Hi,
I have a problem placing orders with iphoto. Ordering procedure ok till sending files. Then nothing happens. Internet, email, itunes, account everything ok. security - firewall ok. husband is having same comp. and no problems with his or my account when ordering prints, calendars or books. on my computer its seems impossible. ilife 08 already removed and reinstalled, problem stays the same. helpdesk till now unable to help me.
I hope some one can help me, and if possible ASAP
ThanksTry trash the com.apple.iPhoto.plist file from the HD/Users/ Your Name / library / preferences folder. (Remember you'll need to reset your User options afterwards. These include minor settings like the window colour and so on. Note: If you've moved your library you'll need to point iPhoto at it again.)

Hi, I have problems in ordering book from iPhoto. It says "problems in getting contact with Apple Online Store" I have changed password on my Apple ID - could that be the problem ??
Some additional efforts you can try:
Go to the System/Sharing preference pane and make sure Remote Apple Events is checked.
If it is, uncheck it and then recheck and try ordering again.

hi guys
i m having a problem in ordering by in a detail block .
actually i have a dummy block on whose basis records are populated in a detail block the
when_button_press has
go_block('x');
execute_query;
there is a where clause in the block level and no order by clause.
althogh the query which is generated by forms when run on sql gives me the desired result but not in the forms.
also for elaboration the ordering is to be done on the basis of another table which stores the display order for the records so when I tried using both tables in the forms block QUERRY DATA SOURCE NAME and joined the 2 table in the where and order by caluse of the block level and the column source at the field level was given table_name.column_name but the query build by the form inclued the rrowid for the table whICH i CAN NOT alias so there was a problem in the query genetration and hence the result
please tell me what is the problem here...
thankx
dgok guys dont scratch ur heads the problem has been solved
thankx anyway

Problems with 'Order Prints' from Aperture 2.1.3 Mystery borders
*Some background:*
I've been using Aperture for about 3 months now, importing most of my iPhoto library into the program. I have only recently started shooting in RAW format, most of my photos image files are in JPG format. In the past, I've had no problems with obtaining prints from within iPhoto or to a limited extent Aperture. So, far as I know my program is up-to-date. I have 2 plugins installed: Aperture2twitter and *flickr export Lite* both of which work acceptably.
*The problem:* I ordered 317 4×6 prints from my aperture library.
Every photo has a 1/4″ border on both sides of the image, i.e. the printed image is only 4×5 1/2″. I have never ordered this quantity before, but I don’t believe that was the problem, it appears that the processing machine was misaligned and no one reviewed the prints prior to shipping.
I tried again, on 4 different images ... all JPG files with 3 out of 4 were OK, but one exhibited the "border" issue.
I haven't a clue what is going on here. Apple implied +(via email)+ that I would have to individually crop every photo to ensure proper aspect ratio. This makes no sense to me at all, as I have never had this kinda problem before.
Could the plugin(s) be interfering with the s/w? Is there a trick to having photos printed from within Aperture that was not present in iPhoto?
Any thoughts on what the problem is would be greatly appreciated.
Thanks
-johnI believe that I've solved this problem, with the help of the folks at Apple who handle Aperture tech support using the Aperture support ID that came with the product.
So the short answer is: Aperture print services REALLY DO REQUIRE the image to be cropped (constrained as they say) prior to the data being sent to Apple Print services.
Here is the link that describes cropping http://support.apple.com/kb/HT1993?viewlocale=en_US
The process as described is cumbersome, but the support tech pointed out that in Aperture, crops are 'non-destrutive' and can be undone simply by removing the check mark on the Adjustments tab of the image you crop. *This means that you do not have to make a duplicate image for cropping.*
So, here is the process that I arrived at to ensure that my "order prints" job turned out:
1. create an album of all the photos you want to submit for printing.
2. for each image call up the Crop HUD by pressing 'c' on the keyboard.
3.select the aspect ratio that you want for your photo. Make sure that it does NOT SAY Master Aspect Ratio, or Main Display Aspect Ratio.
4. Crop the photo
on the adjustments tab you can see the X and Y data and Height / Width information which can be undone.
5. Submit your print request to Apple for all the cropped photos.
When the prints arrive, you can compare the prints with the submitted photos. They should all be good. You can then delete the album (since it really is not a physical thing) or keep it for reference.
It all seemed a bit arcane to me, as I never had to worry about this in iPhoto. It must be that iPhoto sends different data than Aperture. I have just received 200 + prints back from Apple Print Services with about 98% success rate. I just have to adjust my thinking and my process when dealing with Aperture. -
Hai all,
I have problem with order by clause,
My query is
"select number from table1 order by number asc "
and the output is displaying as
1
10
12
13
15
17
19
2
20
21
22
But if we give order by it should display as below only right ?
1
2
10
12
13
15
17
19
20
21
22 ........
Please help me why it is not displaying like it. and how to make the statement to display like the second case. Thanks in advance.
Regards,
UrajaThe column datatype that you are selecting is not of NUMBER datatype(might be char or varchar2) hence you are getting such result set.
And for this purpose, it is recommended to set datatype of a column appropriately.
For now you can add TO_NUMBER function to column in ORDER BY clause, only if it has data of number type.

Ad Control not showing above Unity3d window even if draw order is adjusted
I am using Unity3d and Visual Studio to release a simple game. I already have a paid version released and working great. I am trying to make an ad supported version with little luck.
I added in the Ad Control item into design view and attempted to adjust the Unity window so that it sits below where the ad banner will sit. I have even tried to adjust the Ad Control draw order to various numbers higher than 0 (not sure if that should
help or not).
When the game starts, there is a "flash" of a red outline where the ad should be, but then it disappears, presumably behind the Unity window. This area is also not pressable, it blocks the presses on my game where the ad should be.
Is this something to do with the Unity object window parameters, or is there something else I may have to do to get my ads to work?
Thanks!
NickHello,
Welcome to MSDN forum.
I am afraid that the issue is out of support range of VS General Question forum which mainly discusses
the usage of Visual Studio IDE such as WPF & SL designer, Visual Studio Guidance Automation Toolkit, Developer Documentation and Help System
and Visual Studio Editor.
Because your issue is related to Unity3d which is third-party, I suggest consulting your issue on Unity3d community:
https://unity3d.com/community for better response in order to resolve your issue as soon as possible.

Drawing order of curve behind loaded movie
Hi,
I'm having an issue with the draw order of curve that's drawn
using Actionscript. In terms of the order of execution of the
function call, I have a SWF loaded first using the loadMovie
function. Then I call the curveTo function with certain parameters
to try to draw a curve on top of the loaded movie. However, the
strange behavior is that the line is hidden behind the movie clip.
I've used swapDepths, but it wasn't working for me. Also tried
using the createEmptyMovieClip function with a depth number
assigned, but didn't do the trick. Any suggestion?1. there's no reason for an onEnterFrame loop.
2. there's no reason to use any setInterval() functions in the code you showed.
3. you should be using the same function to load your swfs. if some logic is needed to position, for example, the different swfs in different locations, the logic should be in that function.
ie, you should be using something like:
_level0 swf:
function nextMov(){
loadF(MovieList[movieQNum]);
movieQNum=(movieQNum+1)%MovieList.length;
function loadF(swf:String){
dep = getNextHighestDepth();
currLo.removeMovieClip();
currLo = createEmptyMovieClip("currLo"+dep, dep);
loadMovie(moviename, currLo);
//move the loaded movie behind movie frame
BlackMovieFrame.swapDepths(currLo);
function endSession(mc:MovieClip){
mc.removeMovieClip();
nextMove();
// in the loaded swfs:
var tl:MovieClip=this;
btnArrow.onPress = function() {
_root.endSession(tl); -
Hi, I have a problem with order data. A string column has these values:
A....
B....
PSTA-FRA
PSTA+FRA
Q....
R....
If i order data directly from db ( select column1 from table order by column1 ) , i obtain this result:
PSTA-FRA
PSTA+FRA
If i create a simple report on that table and order on that column the result is:
PSTA+FRA
PSTA-FRA
I can obtain correct output if I set parameter 'Perform group on server' but if i write a selection formula :
{table.column} >= 'PSTA+FRA'
record containing PSTA-FRA value not appear.
I've tried both with Crytal 8.5 and Crystal 11 R2 sp6, database is Sybase SQL Anywhere odbc connection.
Thanks in advanceOrdering is done according to the ASCII values of the characters.
In R2 create a new report and log onto your DB and select Command for your data source. Paste in the SQL you use to get the data in the order the server users. Then you don't have to use CR to do the sorting. DB Servers are much more efficient at collecting the data than CR is.
Thank you

the inclusion of the 'type' Image makes them local to the constructor -
Is there a way in MXML to specify drawing order? I'm
relatively new and the only thing I can see in MXML to specify
drawing order is to declare the components in the order you want
them drawn. Let's say I have two panels,
p1 and
p2, and one extra state
s2. What would I put in
s2 to make
p1 appear on
TOP of
p2 in
s2???
<mx:states>
<mx:State name="s2">
</mx:State>
</mx:states>
<mx:Panel x="10" y="10" width="250" height="200"
layout="absolute" id="p1" title="Panel 1">
</mx:Panel>
<mx:Panel x="40" y="40" width="250" height="200"
layout="absolute" id="p2" title="Panel 2">
</mx:Panel>
Thanks much in advanceYou are correct in that drawing order is related to the order
in which components are added to the display list. That's the
default behavior using the addChild() method of a container. You
can also use addChildAt( child, index ) to specify a position.
If the children are already in place you can swap their
positions or move one child into a specific position. For example,
if you have two children, the positions are 0 and 1. If you want 1
to become zero, then use setChildIndex( child, 0 ) and that
component will be moved behind all others.
Doing this in a state change is difficult since the order
isn't a property of the child, you must execute a function. I
suggest just doing it in ActionScript either before or after you
switch states. -
Problems in order to build DarkRadiant editor

And I can't compile it,
I have tried using AUR but it is even worst, the package installs correctly, but when i run the editor:
segmentation fault.If it built from AUR why do you you think you'd get a different result from building it manually? All that makepkg does is run the commands needed to build it.
That said, if you want to do it yourself, you should look at the PKGBUILD to see which commands are needed. Use autoreconf instead of autogen, modify the configure script, set the environment variables, and pass the right parameters to configure.
Edit: I just built it from the AUR. I got segfaults after it started when it tried to load files that don't exist (/usr/local/game/doom3). This is an upstream bug, report it there.

i am facing serious problems drawing an arrow which has to be moved round the screen.
does anybody have any idea or reference websites that would solve my problem
i have to rotate the arrow to the mouse pointer to wherever it is dragged.
hope u will get with this nick
hussain52A more descriptive backgound to the problem may help people come up with a solution for you.
From what you've said it sound like you need to use a canvas and paint the arrow on it. Then use a mouse listener to listen for mouse clicks on the arrow and re-draw the arrow appropriatly.
Does this sound like it might work?
If so, try the code below...
It only paints a line, but it might get you thinking in the right direction?
Additions to get it to do what you want are...
1. Draw an arrow head at the end of the line.
2. Listen for mouse clicks within a certain radius of the end of the line.
3. Redraw the line using the original start point and the new end.
However, if I've completely missunderstood then it's all a complete waste of time.... but I've enjoyed it.
Adios amigo.
