language agnostic - How to find the mathematical function defining a bezier curve -

-

I'm trying to implement a bezier curve and line segment transfer test. The closest thing in my search is to carry the mathematical function curve and keep it on the origin to carry the Bezier curve (to limit three control points for simplicity). Then, use the line segment's function as another function and give them equilibrium values ​​and solve the equation.

The solution above from many sources (unless they misunderstood), my problem is that I can find a way

Oh, and please indicate that if I intersect I am completely away from the track to find the point (signs).

A beijier curve is a parametric function. Can be expressed as a quadratic beijier curve (i.e. three control points): f (t) = a (1 - t) ^ 2 + 2b (1 - t) t + whistle ^ 2 where a , b and c are digits and t goes from zero to one.

This will give you two equations:

x = a (1 - t) ^ 2 + 2b (1 - t) t + whistle ^ 2

y = kx + x = y = d (1 - t) ^ 2 + 2e (1 - t) t + Ft ^ 2

M ), you have three equations and three unknown ( x , y and t ) will end with

c# - How to capture HTTP packet with SharpPcap -

-
I would like to capture all incoming HTTP packets on my machine. To do this, I am using SharpPcap which is a WinPcap The cover is. SharpPcap works very well, but it captures TCP packets and what it wants to do for me is a very low level. Does anyone know how can I easily get full HTTP requests / reactions from all these TCP packets? Thanks SharpPcap is already able to capture the packet in the same way That's what the virus does (just in the code instead of the GUI). And you can either either parse them directly or you can put them in the drive in the common .pcap file format. The steps to parse the capture are: Open a connection at any time Loop a while Or start capturing using an event callback Parsing the raw packet for the type you want If you are reading .PPP dump files In addition to calling you an offline capture reader is almost the same, there is no need to select an interface, and you can set the majority There is no need to do the modes. All st...

php - jQuery AJAX Post not working -

-
I do not understand why this script does not work. It has something to do within AJAX PostScript / Function. Right now, when I submit my form, it runs php code on the same page. What it should do, send the values ​​of the form for Project_Azax.fp, then there will be a refund of success on the page which is correct or false. $ (document) .ready (function () {$ ('div # didIt'). Hide (); $ ('form [name = adminForm]'). Submit (function () ($ {'.post' ('/ project_ajax.php', {action: $ ('[name = action]') Val (), pId: $ ('[name = pId]'). Val (), name ('[Name = name]'. Val (), url: $ ('[url = url]'). Val (), summary: ('[summary = summary]'). Val ()}, Function (data) {if (data.success) {$ ('div # didIt') .Sliddown ('slow');} and {warning ('unsuccessful SA!');}}, 'Jason'); return false ;});}); What is the code for project_ajax.php below ... if ($ _ POST ['action'] == ...
