Shape rotation question

i am wondering how to rotate a shape, such that I can still check for intersections, etc, with the shape in it's rotated state. I know Graphics2D has a rotate method, but that wouldn't allow me to check for an intersection between a rotated rectangle (e.g 45 degrees around central axis) and an ellipse2d.
can AffineTransform or PathIterator help?

thanks fred, that might be just what I need. Can someone confirm this psuedocode:
1. Convert shape to Area
2. Create AffineTransform and rotate it by x radians
3. Set transform of Area to affinetransform
4. Call intersects method of ellipse
thanks

How to make shape rotation at it's center point?

I draw a shape,like follows:
var shape1:Shape;
shape1=draw();
addChild(shape1);
shape1.rotation=50;
private function draw():Shape{
   var shape:Shape = new Shape();
   shape.graphics.beginFill(0x00FFFF);
   shape.graphics.moveTo(200,200);
   shape.graphics.lineTo(300, 202);
   shape.graphics.lineTo(200, 204);
   shape.graphics.lineTo(100, 202);
   shape.graphics.lineTo(200, 200);
   return shape;
Then I want to rotate the shape at it's center point(200,202) by using shape1.rotation=50,but I find the shape don't rotate at the the center of it's shape. How to realize the function which make shape rotate at its center point?
Thanks

Here is a sample to make it rotate from center:
var sprite:Sprite=new Sprite();
sprite.graphics.lineStyle(3,0x00ff00);
sprite.graphics.beginFill(0x0000FF);
sprite.graphics.moveTo(0,0);
sprite.graphics.lineTo(100,0);
sprite.graphics.lineTo(100,100);
sprite.graphics.lineTo(0,100);
sprite.graphics.lineTo(0,0);
sprite.graphics.endFill();
var mc:Sprite=new Sprite();
mc.addChild(sprite);
//This will make the sprite to center
mc.getChildAt(0).x=-(mc.getChildAt(0).width/2);
mc.getChildAt(0).y=-(mc.getChildAt(0).height/2);
addChild(mc);
mc.x=200;
mc.y=300;
//Now it rotates from the center.
mc.rotation=20;

3D repousse objects and linking / rotation question

In Photoshop CS5 Ext, I have 4 layers, each with a 3D repousse object on them. I want to somehow link them, so that I can rotate the object as a whole (or the camera), but also want to still be able to manipulate the objects separately (like rotate and position). Is there a way to do this in PS, or does this need to be done in another program like Flash? Tried unsuccessfully using merge 3D, linking, grouping...
Thanks,
John

Thanks Steve for the reply and screenshot.
I see that 3D panel will let me rotate, etc., but it doesn't look like I will be able to rotate objects separately using animation from the timeline, will it? That is another thing I forgot to mention that I want to do, is be able to animate (rotate and move) the objects separately.
Thanks,
John

Hi John,
Merging 3D layers should be what you want. When you tried this what failed? If it was that you could only transform all of the objects instead of each separate object, then you'll need to make sure you are using the appropriate 3D tool. The UI needs some work to make this a bit easier to discover.
There are 3D Mesh tools in the 3D panel that allow you to manipulate individual meshes, instead of the whole scene (3D Object tools).

3D shapes rotation axis

Is there a way that I can automatically place the rotation axis on a 3D shape in the dead center of the shape (on the X,Y and Z axis) or do i have to just do it by hand?

If the shape was drawn with the pen tool then you have to position the shape's anchor point by hand.
If the shape was created with the Shape tools then you can reveal the transform shape properties and reset the position property to 0,0
If the shape has a odd number of sides, like a triangle, this will not work properly so you will have to eyeball the shape center.
I usually use the Transform properties for the shape for this instead of using the Layer Anchor point because it is easier to be accurate with even sided shapes than using the layer's anchor point or the anchor point tool.

Help Combining Shapes Rotate

Hello Everyone ... Level: Newbie OS: Win7 64bit PS: Cs6
I have made a Rectangle of which I have altered the shape
Next and on the same layer I have selected the Ellipse tool and set it to Combine Shape
then I have been creating small circles and placed them down the left and right side ~ I have placed the circles half on the Rectangle and half off
however, when I go to Rotate the object(s) they are no longer Combined and will not Rotate together .... ??
any ideas?
Oh, also ... I am repeating the circles from top to bottom and I would like to keep them percisely in line but when I use Direct Selection tool to select the first circle made and then use Copy & Paste and then use the arrow keys to move the circle straight up ... are these Copied and Moved circles still in Combine Shape mode? Just Wondering because it doesn't seem like they are still combined.
I've deselected by clicking the Move tool after making all the circles but that doesn't help either.
Thank you

When the shapes are all in one layer they will rotate as a unit unless you use the Path Selection Tool to select some path(s) and not others and then rotate.
You don't have to copy and paste to duplicate paths in a Shape layer. You can Opt/Alt-drag with the Path Selection Tool to duplicate and move. Combine with Shift key to constrain to horizontal/vertical. The PST also has alignment and distribution options.
Smart Guides (magenta lines) are a great aid to alignment but to use them you'll have to make separate Shape layers and then merge after they're aligned

Image degradation caused by rotation question

When I rotate an image from a horizontal to vertical orientation using iPhoto8 on my 24" Intel-based iMac, the image is reduced in size and loses sharpness. Is this loss in sharpness because the monitor is no longer displaying the image at a correct pixel ratio or is it a software problem like the lack of a lossless rotation routine in iPhoto?
Thanks, Rick

I may be making some assumptions here but let me try and answer. Since the 24" iMac screen is almost twice as wide as it is tall, it stands to reason that when you rotate an image it will reduce in size. Or at least that will be the case if you were using a large portion of the wide screen to display the image horizontally in a landscape orientation. Anytime an image is reduced in size, it stands to reason that detail will suffer because fewer pixels are being used to render the image on the screen. Does that make sense or am I totally misunderstanding the question?

Simple shape fill question

Ok ... i've been using photoshop since 1.0, and this has to be an elementary question - i'm just blanked.
I drew a shape with the pen tool, closed it by clicking on the starting node.
But the fill is "outside" the shape and not "inside".
I've never seen this happen before ...i've drawn literally thousands of shapes (tracing images etc as you would in illustrator or other vector-drawing programs).... what gives? how do i get the shape fill "inside" the shape and not "outside"?
thanks.

WPA Key Rotation Question

Hi All,
In an AP, the broadcast-key change <value> command tells the AP how often to rotate the WPA key. My question: How do clients remain connected to the Wireless LAN when the key rotates? If the client authenticates (via Radius in my example below), then I would think the key challenge would need to be met. However, if in 5 minutes the key rotates, for example, isn't the client going to lose connection since the challenge value is now different? The only thing I can think of is that Radius handles this dynamically once a client is authenticated, thus avoiding any disruption. Is this correct?
Here is my config, if interested:
aaa new-model
aaa group server radius employee-clients
server 10.255.255.250 auth-port 1645 acct-port 1646
aaa authentication login console local
aaa authentication login net-admin local
aaa authentication login eap_methods group employee-clients
aaa authorization exec default local
aaa session-id common
dot11 ssid WLAN-Local
   vlan 20
   authentication open eap eap_methods
   authentication network-eap eap_methods
   authentication key-management wpa
interface Dot11Radio0
no ip address
no ip route-cache
encryption vlan 20 mode ciphers aes-ccm
broadcast-key vlan 1 change 300
radius-server host 10.255.255.250 auth-port 1645 acct-port 1646 key <key>

All dot1x clients have a unique key but share a seperate broadcast key that is derived through the dot1x process. To rotate that key use this command ( broadcast-key vlan # change #) on the radio interface. . but the WPA cypher key which keeps on changing after some interval is to encrypt the data with different differnt keys so that it wil be difficult to be cracked/decrypt and not for reauthentication of clients.

Shape rotation using mouse

Hi,
I�m interested in rotating a shape by dragging the mouse.
For example, visualise a rectangle, now imagine pressing the mouse on the top left-hand corner, then dragging that corner down, with the mouse, to rotate the shape. That�s what I want to do.
Has anyone got any thoughts on this?
Thanks,
Luke

it seems to rotate too much or some thing
In the DragRotation class each rotation event is referenced to the original, non–rotated rect. When you redefine the shape each time then each rotation will have to be referenced to/from the last/current shape angular position. If it is already rotated and you rotate it with the current_rotated_angle plus the angle referenced to the original non–rotated rect you will get too much rotation. We have to change the way we reference the rotation.
If I start walking from Los Angeles to Chicago and measure my distance from LA each time I arrive at a new town, okay. If I measure the distance from town to town it is a different way to reference the distance walked. If I leave Denver, at a distance of 1000 miles from LA, and walk to Omaha, a distance of 550 miles, I would have walked a total of 1000 + 550 miles. But if I get confused about the counting and add the total from LA to Omaha to the miles walked on the last leg (from Denver) it would appear that I walked 1000 + 550 + 550 miles. So we need to be clear about how we are measuring the distance traveled.

GC log rotation question

Hi,
So after JDK 1.6.0_34 (as far as I know), java introduced GC log rotation JVM args (see below)
-XX:+UseGCLogFileRotation -XX:NumberOfGCLogFiles=10 -XX:GCLogFileSize=1M
Prior to these JVM arg additions, on any java application start, your GC log would get wiped. In my case a tomcat server running java code.
So now I would assume when these JVM arg's are present, the GC log continues to rotate and not get wiped on application start up. However the above behavior still persists ever after JDK 1.6.0_34 with the new JVM args present.
I should mention while the java application is running, the GC log DOES rotate (i.e., gc_log.txt.0, becomes gc_log.txt.1), but when application is restarted the LAST GC log is erased completely.
This behavior isn't really "log rotation/backup", I've had to introduce my own shell/bat scripts to rotate the latest GC logs manually outside of these JVMargs. I'm not sure if I'm misunderstanding how to use the new JVM args or if oracle doesn't consider this a bug and this is normal behavior.
I did file a bug on this, 9005051. However there is no guarantee your bug request ever makes it to the public bug database and oracle doesn't provide reasoning back to the submitter when the bug is rejected or not looked at, so I don't really know what happened with my bug request.
If anyone has any insight into this, I would really appreciate it.
Thank you!

> Or better yet, where I can find someone to actually answer my question?
Me! Me! I know the answer to that question...
Oracle is more than happy for you to pay them for a support\service contract of which part of that will be that you can ask them questions and they will answer them. Real Oracle engineers and perhaps the very people who created the code in the first place. Or at least the ones in charge of it now.
> yet there is no guarantee my bug is even a bug or will even get posted to the bug database
Yes that is true.
But I suspect, strongly, that if you have a big enough contract that every bug you post to the database, and that you tell oracle about, will appear promptly and be addressed promptly.
And if you have a smaller (but not really small) Oracle contract I am rather certain that you can obtain a custom fix.
Alternatively you can download the source, figure out the problem, and fix it yourself. Then apply it to your running services.

Is this even possible? (Rotation question)

Hi! I'm new to Java 3D... What I am trying to do is to rotate one transform group around another transform group. i.e. get a moon spinning the earth does anyone know how to do this? I am posting my code below.... I've searched the forums already and alas found no answer :( I've tried everything as you can see from the bottom of the code where all the "garbage" is. The actual earth has been commented out so that I can see the moon. Any help would be greatly appreiciated!! Thank you in advance! -JET

Yes it is possible. Build a scene graph where the TransformGroup of the moon is a child of the TransformGroup of the earth.
TG1 __________ Earth Shape3D
|
|____ TG2 ___ Moon Shape3D
In this way the overal transformation for the moon is the concatenation of TG2 and TG1. The transformation for the moon TG2 has to be given relative to the earth (i.e. the middle of the earth is the center of the local coordinate system for the moon).
If you want the earth spinning then build the following graph:
TG1___ TG3 ___ Earth
|
|____ TG2 ___ Moon
Put the transformation of the earth position in TG1. Put the spinning transformation of the earth in TG3 and the position transformation of the moon relative to the earth in TG2. Thus the spinning of the earth will not interfere with the position of the moon.

Shape layer questions

I’m a web designer that’s used to using Illustrator for all my work. Recently many of my new jobs want me to work in Photoshop, so I’m getting back up to speed with it. I have a few nagging issues that I haven’t been able to figure out:
With the direct selection tool, how do I select a small shape that’s overlapping a larger shape? For example, a small line on top of a large rectangle. When I try to do this Photoshop automatically makes me select the larger shape in the background. I have to zoom in super close and individually shift-select each corner of the smaller shape before I can move/transform/whatever it. This gets tedious and slow real fast!
Recently in a document I’m working in, whenver I make a new shape it automatically adds a bunch of layer styles like drop shadow, stroke, etc. These styles aren’t turned on, but it adds unecessary styles to my layers and my client is very strict about recieving only super clean .psd’s.
How do I make a line that is truly 1px stoke width? My lines seem to always start out as fuzzy 2px worms until I zoom in and surgically make them 1px. Again, what a waste of time! is there some sort of antialiasing setting that I need to turn off?
Thanks!

1. With smaller shapes that are difficult to select, try selecting their layer first. If you are not sure which layer, switch to the Move tool (V), hold Ctrl and click on the small shape. With the default behavior in Photoshop you should be able to select the layer and then use the Direct selection tool to select points on the vector path of the small shape. If you want to just move the entire shape when its the only path on a layer, aside form using the Path Selection tool (black arrow), you can just use the Move tool (V) to change the position of the layer. If you have to deal with a lot of shape layers that you just want to click and move, enable the Auto Select for the Move tool in the Properties bar. Then holding Ctrl while using the tool will toggle to its non - Auto Select mode.
2.On the Tool's property bar under the main menu, make sure the chain button is not pressed then click on the Style swatch or arrow to the right of the chain button to open the style swatch popup and from its menu there choose No Style. Next shape layer you make will not have the current style automatically applied.
3. I'm using CS5 on a pc and creating 1 px straight line with the Line tool is buggy with its alignment to grid. The Line Tool draws lines in Shape mode as rectangle vector paths. The difference between the Rectangle Tool and the Line tool is that the Line tool aside from having a Weight attribute, it draws the rectangles starting from the middle if its side. In order to snap it to grid you have to set the grid in the settings to Gridline every 1 pix and Subdivisions 2. If properly working this is supposed to solve your problem if you enable snap to grid and draw your lines starting in the middle of a pixel. The problem is that this doesn't work properly with the Line Tool which does not snap perfectly to the grid. The work around is to draw your lines with the Line Tool in Fill Pixels mode which has an Anti-aliasing option that you can turn off.
Another alternative for drawing lines on raster layers without anti-aliasing is to use the Pencil tool and hold Shift while dragging with it. The Pencil Tool in Photoshop is the same as the Brush tool but without anti-aliasing. I think more proper name would be non - anti-alised brush.

Ad rotator question

I need to add a class to the image tag in the ad rotator, is this possible?
If so how/where?

Hi,
the main objective to install a domain controller in each site is to avoid the authetification through a domain controller in another site, to reduce VPN connection and ensure the availability of domain in each site in case of VPN connection
is down.
So it's recommanded to configure your sites and subnet to let computers contact the local DC for performance reason.
To ensure that all computer and servers ask the local domain controller, you must add their subnet in site which contain the local domain controller through the sites and services wizard.
if the local DC will not be available ,client will try to contact another available DC, not with the same performance because it will use VPN connection, to avoid this situation , you can install another DC in the same site.
For DNS , just put the local DNS as primary one, and choose a DNS fom another site as secondary , with this configuration Client will able to detect all domain object, and DNS record (with all Subnet network).
If your sites is not totally you can configure bridge site manually to get more information please check theses links below:

IOS 6 auto rotation question?

I updated the software for my 3GS to IOS 6. However, I noticed when viewing my Facebook page, the screen doesn't not auto rotate from portrait to landscape. Is this by design or is there a glitch?

STEP 1
Press the "Home" button below the iPhone screen twice to display the icons for recently used apps in the bottom status bar.
STEP 2
Swipe the status bar from left to right until you see the screen lock icon, which is a padlock inside a circular arrow.
STEP 3
Tap the screen lock icon to turn off the screen lock. The padlock icon will disappear and screen rotation should unlock.
STEP 4
Press the "Home" button again to return to hide the status bar.
STEP 5
Launch an app that you know allows screen rotation, such as the "Calculator" app.
STEP 6
Rotate the iPhone to ensure that the Calculator screen also rotates. If the screen moves as expected, you have successfully removed the lock. If the screen remains locked, press and hold down the "On/Off" button and then swipe the "Slide to Power Off" tab to switch off the iPhone. Press the "On/Off" button to power on the iPhone.

Rotation Question

i am making a simple picture racing game and i want to know what is the best way to make wheels spin when you go with no blinks and smooth animation, i am using JPanel. will it be better to make program rotate image itself or make different images myself. if making program rotate it itself is the better way what is the best way to do it, thx for reading.
