javascript - Algorithms for positioning objects in a canvas -

-

Where can I find some algorithms for moving some objects in a clever way in the canvas? I am using Javascript (with Raphael SVG Library), but examples of other languages ​​(or pseudo-language) are welcome. Geometry is not my strong point =)

For example, 600x800 canvas is, and I want to place the size n in the smart ways 60x60, for example:
- One . Conditions with an algorithm for position meters concentric sections, but an alternate - algorithm for the location m condensed o offset with circles With the commodities frequency (the result may be like a chess)

And similar examples .. I'm just looking at some examples of work to be suited to my case. In advance, thank you =)

for circle:

Input: CenterPt (possibly 300,400 ), RadiusLargestCircle (possibly 270 to ensure your objects are RadiusDelta on all screens) 60 assures the objects are circles)

circles (calculate the number of RadiusLargestCircle -2 * RadiusDelta Overlapping objects) / RadiusDelta

For each cycle 

  RadCir = RadiusLargestCircle - (CircleNum * RadiusDelta)

(I Will end soon

But essentially the first object goes to centpt X = radiusLargestCircle, y = 0

the division object 2 * radius in the circumferance of the circle

For the number objects

using the parametric equation of the circle, the object on the last one to the x radius

the next circle

After selecting the copies of the buffer in Linux, after the text, we can click and paste the button between the mouse. I think there is a special buffer for this, I want to use it. Programming Language: C ++ Your Library: Qt Thanks. There is just one more correct answer than Paul Dixon, which answers your needs: / P > QClipboard * clipboard = QApplication :: clipboard (); CastString Selected Text = Clipboard-> Text (QClipboard :: Selection);

Visual Studio 2005: How to speed up builds when a VSMDI is open? -

-
Using Visual Studio 2005, if I open the test in VSMFI and try to run the tests, then sometimes the projects are ready. However, they run very slow. CPU 99% waste and output window VS Shows things associated with compiling it. Is there any way to fix this? It does not make any sense. It is not necessary to upgrade that we are a viable alternative to those people who have to deal with the legacy code. Did you try to upgrade SP1? I do not know of any specific problem in this area, but this will be the first change I tried to do.

booting ubuntu from usb using virtualbox -

I am trying to install Ubuntu on a USB, the problem is that I do not want to repeat the boot once, I want to keep my windows, but I want to boot Ubuntu using the virtualbox and USB to the Ubuntu Want to use my hard drive, but how? The virtualbox will not recognize USB as a hard drive when installing an ISO In virtualbox, you have to create a virtual hard disk. Make a USB drive and tell the virtual box to install a virtual hard drive that you just created. EDIT: To answer some more questions: In the new Virtual Disk dialog, click the button next to the location field, click on the button Virtual Disk on Flash Drive To access, click the arrow next to Save in the Select File in the window next to Save In, and you can access your flash drive from there. I recommend setting the image to be allocated dynamically, because the size of your flash drive is not available disk space. I name the image, then select that image to install Ubuntu in the Verbill box. The virtualbox will never...
