traversal

I need the same thing done here , but to work with any matrix, not just a square one. Also, the direction of traversal needs to be opposite. I tried to edit the code I found there, but couldn't figure it out. Thanks. I remember writing that. I think for a rectangular matrix you'd need a few minor changes and one more line of incomprehensible nonsense: #include <stdio.h> int main() { int x[3][4] = { 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12}; int m = 3; int n = 4; for (int slice = 0; slice < m + n - 1; ++slice) { printf("Slice %d: ", slice); int z1 = slice < n ? 0 : slice - n + 1; int z2 = slice <

I'm looking for a good ray-octree intersection algorithm, which gives me the leafs the ray passes through in an iterative way. I'm planning on implementing it on the CPU, since I do not want to dive into CUDA just yet :) At the moment, my Voxel raycaster just does 3D DDA (Amanatides/Woo version) on a non-hierarchic array of XxYxZ voxels. You can imagine that this is pretty costly when there's a lot of empty space, as demonstrated in the following picture (brighter red = more work :) ): I've already figured out that there are two kinds of algorithms for this task: bottom-up , which works from

Lets say I have an unordered nested list: <ul> <li>Item a1</li> <li>Item a2</li> <li>Item a3</li> <ul> <li>Item b1</li> <li>Item b2</li> <li>Item b3</li> <ul> <li>Item c1</li> <li>Item c2</li> <li>Item c3</li> </ul> <li>Item b4</li> </ul> <li>Item a4</li> </ul> I need to traverse it and save it in a two dimensional array (ultimately I'm just trying to convert it into a JSON entity) I am allowed to use both Jquery AND/OR Javascript. How should I proceed? Thanks I'm not sure exactly what you want the resulting data structure to look like, but this (which uses some jQuery): $(function() { var

Does anyone know a library that allows DOM traversing in strings using a jquery like selector engine? dev-null-dweller Many out there, pick one that suits you: http://code.google.com/p/phpquery/ http://querypath.org/ http://jquery.hohli.com/ http://simplehtmldom.sourceforge.net/ few more can be found in similar question (link thanks to @Gordon) How do you parse and process HTML/XML in PHP? 来源： https://stackoverflow.com/questions/4417446/php-jquery-like-selector-engine

I am trying to do make some text show when a text input is on focus, but the closest(); method doesn't seem to be working. I have done a JS Fiddle for you to look at. and here is the code also. JS $(document).ready(function(){ $('.validation-error').hide(); $('.name-input').on("focus", function(){ $(this).closest('.validation-error').show(); }); }); HTML <fieldset> <legend>User Details</legend> <table> <tr> <td width="200"> <label for="user"><span class="required-fields">*</span> User Name</label> </td> <td> <input type="text" id="user" class="name-input"> </td> <td> <p class="validation-error

I'm writing some cross-platform code between Windows and Mac. If list::end() "returns an iterator that addresses the location succeeding the last element in a list" and can be checked when traversing a list forward, what is the best way to traverse backwards? This code workson the Mac but not on Windows (can't decrement beyond first element): list<DVFGfxObj*>::iterator iter = m_Objs.end(); for (iter--; iter!=m_Objs.end(); iter--)// By accident discovered that the iterator is circular ? { } this works on Windows: list<DVFGfxObj*>::iterator iter = m_Objs.end(); do{ iter--; } while (*iter != *m

I am trying to accomplish UDP hole punching. I am basing my theory on this article and this WIKI page , but I am facing some issues with the C# coding of it. Here is my problem: Using the code that was posted here I am now able to connect to a remote machine and listen on the same port for incoming connections (Bind 2 UDP clients to the same port). For some reason the two bindings to the same port block each other from receiving any data. I have a UDP server that responds to my connection so if I connect to it first before binding any other client to the port I get its responses back. If I
