  • Determining line orientation using vertex shaders

    - by Brett
    Hi, I want to be able to calculate the direction of a line to eye coordinates and store this value for every pixel on the line using a vertex and fragment shader. My idea was to calculate the direction gradient using atan2(Gy/Gx) after a modelview tranformation for each pair of vertices then quantize this value as a color intensity to pass to a fragment shader. How can I get access to the positions of pairs of vertices to achieve this or is there another method I should use? Thanks

  • how do you create a simple obejctice-c command line project in xcode

    - by Mark
    im moving from a c# VS2008 world into the mac world and I just wanted to know how I can create a quick little command line based application so that I can write many little objective-c apps without worrying about creating an iPhone app or whatever. Which projects do I create in xcode? I can see the Command Line Tool under "Mac os x" but the only options for the type is "C", "C++", "Core Data", "Core Foundation", "Core Services" and "Foundation" but no simple objective c project? Thanks

  • logback - no end of line delimiter

    - by binary_runner
    I'm using logback 0.9.21 . Unfortunately it prints all messages to single line, there is no end of line character, even wrong one. I've got the pattern set right AFAIK: <pattern>%d{HH:mm:ss.SSS} %-5level %class (%thread) [%logger{36}] -- %msg%n</pattern> What's the catch?

  • Paste a multi-line Java String in Eclipse

    - by Thilo
    Unfortunately, Java has no syntax for multi-line string literals. No problem if the IDE makes it easy to work with constructs like String x = "CREATE TABLE TEST ( \n" + "A INTEGER NOT NULL PRIMARY KEY, \n" ... What is the fastest way to paste a multi-line String from the clipboard into Java source using Eclipse (in a way that it automagically creates code like the above).

  • Count number of occurrences of a pattern in a file (even on same line)

    - by jrdioko
    When searching for number of occurrences of a string in a file, I generally use: grep pattern file | wc -l However, this only finds one occurrence per line, because of the way grep works. How can I search for the number of times a string appears in a file, regardless of whether they are on the same or different lines? Also, what if I'm searching for a regex pattern, not a simple string? How can I count those, or, even better, print each match on a new line?

  • Read a file from line X to line Y ?

    - by thedp
    Hello, Is there a way to read a file in PHP5 from line X to line Y into a string, without reading the entire file. I would like to return huge files (10,000+ lines) using ajax requests. Each request will provide the client with additional lines. And due to the fact that the file can reach large sizes, I would like to avoid reading it whole over and over again. Thank you.

  • Getting n-th line of text output

    - by syker
    I have a script that generates two lines as output each time. I'm really just interested in the second line. Moreover I'm only interested in the text that appears between a pair of #'s on the second line. Additionally, between the hashes, another delimiter is used: ^A. It would be great if I can also break apart each part of text that is ^A-delimited (Note that ^A is SOH special character and can be typed by using Ctrl-A)

  • Write file at a specific value and line

    - by user2828891
    I want to write data at a specified value in a text file from a text box. Here is a example: item_begin etcitem 3344 item_type=etcitem is first line and item_begin weapon 3343 item_type=weapon is second. Well i want to replace item_type=weapon at second line with item_type=armor. Here is code so far: var data2 = File.WriteAllLines("itemdata.txt") .Where(x => x.Contains("3343")) .Take(1) .SelectMany(x => x.Split('\t')) .Select(x => x.Split('=')) .Where(x => x.Length > 1) .ToDictionary(x => x[0].Trim(), x => x[1]); But returns error at WriteAllLines. Here is the readline part code: var data = File.ReadLines("itemdata.txt") .Where(x => x.Contains("3343")) .Take(1) .SelectMany(x => x.Split('\t')) .Select(x => x.Split('=')) .Where(x => x.Length > 1) .ToDictionary(x => x[0].Trim(), x => x[1]); //call values textitem_type.Text = data["item_type"]; And want to write the same value I change on textitem_type.Text after read. I used this to reaplace but replaces all values with same name from line and returns me in text only 1 line. Code: private void button2_Click(object sender, EventArgs e) { var data = File .ReadLines("itemdata.txt") .Where(x => x.Contains(itemSrchtxt.Text)) .Take(1) .SelectMany(x => x.Split('\t')) .Select(x => x.Split('=')) .Where(x => x.Length > 1) .ToDictionary(x => x[0].Trim(), x => x[1]); StreamReader reader = new StreamReader(Directory.GetCurrentDirectory() + @"\itemdata.txt"); string content = reader.ReadLine(); reader.Close(); content = Regex.Replace(content, data["item_type"], textitem_type.Text); StreamWriter write = new StreamWriter(Directory.GetCurrentDirectory() + @"\itemdata.txt"); write.WriteLine(content); write.Close(); }

  • Displaying data points in Flex Line chart...

    - by dmose
    I have a flex line chart. Instead of the default behavior of having to hover over parts of the line to see the data points, is there a way to change the rendering of each point and have them always displayed? (almost like a connect the dots type view).
