  • Is there anything wrong with my texture loading method ?

    - by José Joel.
    I'm a noob in openGL and trying to learn as much as possible. I'm using this method to load my openGL textures, loading every .png as RGBA4444. I'm doing anything incorrect ? - (void)loadTexture:(NSString*)nombre { CGImageRef textureImage =[UIImage imageWithContentsOfFile:[[NSBundle mainBundle] pathForResource:nombre ofType:nil]].CGImage; if (textureImage == nil) { NSLog(@"Failed to load texture image"); return; } textureWidth = NextPowerOfTwo(CGImageGetWidth(textureImage)); textureHeight = NextPowerOfTwo(CGImageGetHeight(textureImage)); imageSizeX= CGImageGetWidth(textureImage); imageSizeY= CGImageGetHeight(textureImage); GLubyte *textureData = (GLubyte *)calloc(1,textureWidth * textureHeight * 4); // Por 4 pues cada pixel necesita 4 bytes, RGBA CGContextRef textureContext = CGBitmapContextCreate(textureData, textureWidth,textureHeight,8, textureWidth * 4,CGImageGetColorSpace(textureImage),kCGImageAlphaPremultipliedLast ); CGContextDrawImage(textureContext, CGRectMake(0.0, 0.0, (float)textureWidth, (float)textureHeight), textureImage); //Convert "RRRRRRRRRGGGGGGGGBBBBBBBBAAAAAAAA" to "RRRRGGGGBBBBAAAA" void *tempData = malloc(textureWidth * textureHeight * 2); unsigned int* inPixel32 = (unsigned int*)textureData; unsigned short* outPixel16 = (unsigned short*)tempData; for(int i = 0; i < textureWidth * textureHeight ; ++i, ++inPixel32) *outPixel16++ = ((((*inPixel32 >> 0) & 0xFF) >> 4) << 12) | // R ((((*inPixel32 >> 8) & 0xFF) >> 4) << 8) | // G ((((*inPixel32 >> 16) & 0xFF) >> 4) << 4) | // B ((((*inPixel32 >> 24) & 0xFF) >> 4) << 0); // A free(textureData); textureData = tempData; CGContextRelease(textureContext); glGenTextures(1, &textures[0]); glBindTexture(GL_TEXTURE_2D, textures[0]); glTexImage2D(GL_TEXTURE_2D, 0, GL_RGBA, textureWidth, textureHeight, 0, GL_RGBA, GL_UNSIGNED_SHORT_4_4_4_4 , textureData); free(textureData); glTexParameterf(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_LINEAR); glTexParameterf(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_LINEAR); } And this is my dealloc method: - (void)dealloc { glDeleteTextures(1,textures); [super dealloc]; }

  • Whats the easiest way to convert a long in C to a char*?

    - by dh82
    What is the clean way to do that in C? wchar_t* ltostr(long value) { int size = string_size_of_long(value); wchar_t *wchar_copy = malloc(value * sizeof(wchar_t)); swprintf(wchar_copy, size, L"%li", self); return wchar_copy; } The solutions I came up so far are all rather ugly, especially allocate_properly_size_whar_t uses double float base math.

  • Attach file to mail using php

    - by ktsixit
    Hi all, I've created a form which contains an upload field file and some other text fields. I'm using php to send the form's data via email and attach the file. This is the code I'm using but it's not working properly. The file is normally attached to the message but the rest of the data is not sent. $body="bla bla bla"; $attachment = $_FILES['cv']['tmp_name']; $attachment_name = $_FILES['cv']['name']; if (is_uploaded_file($attachment)) { $fp = fopen($attachment, "rb"); $data = fread($fp, filesize($attachment)); $data = chunk_split(base64_encode($data)); fclose($fp); } $headers = "From: $email<$email>\n"; $headers .= "Reply-To: <$email>\n"; $headers .= "MIME-Version: 1.0\n"; $headers .= "Content-Type: multipart/related; type=\"multipart/alternative\"; boundary=\"----=MIME_BOUNDRY_main_message\"\n"; $headers .= "X-Sender: $first_name $family_name<$email>\n"; $headers .= "X-Mailer: PHP4\n"; $headers .= "X-Priority: 3\n"; $headers .= "Return-Path: <$email>\n"; $headers .= "This is a multi-part message in MIME format.\n"; $headers .= "------=MIME_BOUNDRY_main_message \n"; $headers .= "Content-Type: multipart/alternative; boundary=\"----=MIME_BOUNDRY_message_parts\"\n"; $message = "------=MIME_BOUNDRY_message_parts\n"; $message .= "Content-Type: text/html; charset=\"utf-8\"\n"; $message .= "Content-Transfer-Encoding: quoted-printable\n"; $message .= "\n"; $message .= "$body\n"; $message .= "\n"; $message .= "------=MIME_BOUNDRY_message_parts--\n"; $message .= "\n"; $message .= "------=MIME_BOUNDRY_main_message\n"; $message .= "Content-Type: application/octet-stream;\n\tname=\"" . $attachment_name .

  • java: converting part of a ByteBuffer to a string

    - by Jason S
    I have a ByteBuffer containing bytes that were derived by String.getBytes(charsetName), where "containing" means that the string comprises the entire sequence of bytes between the ByteBuffer's position() and limit(). What's the best way for me to get the string back? (assuming I know the encoding charset) Is there anything better than the following (which seems a little clunky) byte[] ba = new byte[bbuf.remaining()]; bbuf.get(ba); try { String s = new String(ba, charsetName); } catch (UnsupportedEncodingException e) { /* take appropriate action */ }

  • Why does OpenGL's glDrawArrays() fail with GL_INVALID_OPERATION under Core Profile 3.2, but not 3.3 or 4.2?

    - by metaleap
    I have OpenGL rendering code calling glDrawArrays that works flawlessly when the OpenGL context is (automatically / implicitly obtained) 4.2 but fails consistently (GL_INVALID_OPERATION) with an explicitly requested OpenGL core context 3.2. (Shaders are always set to #version 150 in both cases but that's beside the point here I suspect.) According to specs, there are only two instances when glDrawArrays() fails with GL_INVALID_OPERATION: "if a non-zero buffer object name is bound to an enabled array and the buffer object's data store is currently mapped" -- I'm not doing any buffer mapping at this point "if a geometry shader is active and mode? is incompatible with [...]" -- nope, no geometry shaders as of now. Furthermore: I have verified & double-checked that it's only the glDrawArrays() calls failing. Also double-checked that all arguments passed to glDrawArrays() are identical under both GL versions, buffer bindings too. This happens across 3 different nvidia GPUs and 2 different OSes (Win7 and OSX, both 64-bit -- of course, in OSX we have only the 3.2 context, no 4.2 anyway). It does not happen with an integrated "Intel HD" GPU but for that one, I only get an automatic implicit 3.3 context (trying to explicitly force a 3.2 core profile with this GPU via GLFW here fails the window creation but that's an entirely different issue...) For what it's worth, here's the relevant routine excerpted from the render loop, in Golang: func (me *TMesh) render () { curMesh = me curTechnique.OnRenderMesh() gl.BindBuffer(gl.ARRAY_BUFFER, me.glVertBuf) if me.glElemBuf > 0 { gl.BindBuffer(gl.ELEMENT_ARRAY_BUFFER, me.glElemBuf) gl.VertexAttribPointer(curProg.AttrLocs["aPos"], 3, gl.FLOAT, gl.FALSE, 0, gl.Pointer(nil)) gl.DrawElements(me.glMode, me.glNumIndices, gl.UNSIGNED_INT, gl.Pointer(nil)) gl.BindBuffer(gl.ELEMENT_ARRAY_BUFFER, 0) } else { gl.VertexAttribPointer(curProg.AttrLocs["aPos"], 3, gl.FLOAT, gl.FALSE, 0, gl.Pointer(nil)) /* BOOM! */ gl.DrawArrays(me.glMode, 0, me.glNumVerts) } gl.BindBuffer(gl.ARRAY_BUFFER, 0) } So of course this is part of a bigger render-loop, though the whole "*TMesh" construction for now is just two instances, one a simple cube and the other a simple pyramid. What matters is that the entire drawing loop works flawlessly with no errors reported when GL is queried for errors under both 3.3 and 4.2, yet on 3 nvidia GPUs with an explicit 3.2 core profile fails with an error code that according to spec is only invoked in two specific situations, none of which as far as I can tell apply here. What could be wrong here? Have you ever run into this? Any ideas what I have been missing?

  • Div not filling width of floated container (css expert needed

    - by Rayden
    I know there are many variations of this question posted, but none I've found quite provide an answer that works for this case. I basically have two left floated divs. Inside those two divs are div headers and tabled content. I want the Div headers (Hour/Minute) to stretch to the width of the tabled content, but they only do this in FF and Chrome, not IE7. IE7 is my works official browser so the one I need it to work with the most. Here is the CSS: #ui-timepicker-div { padding:0.2em; } #ui-timepicker-hours { float:left; } #ui-timepicker-minutes { margin:0 0 0 0.2em; float:left; } .ui-timepicker .ui-timepicker-header { padding:0.2em 0; } .ui-timepicker .ui-timepicker-title { line-height:1.8em; text-align:center; } .ui-timepicker table { margin:0.15em 0 0 0; font-size:.9em; border-collapse:collapse; } .ui-timepicker td { padding:1px; width:2.2em; } .ui-timepicker th, .ui-timepicker td { border:0; } .ui-timepicker td a { display:block; padding:0.2em 0.3em 0.2em 0.5em; text-align:right; text-decoration:none; } Here is the HTML (did not include tabled content): <div style="position: absolute; top: 252.667px; left: 648px; z-index: 1; display: none;" class="ui-timepicker ui-widget ui-widget-content ui-helper-clearfix ui-corner-all" id="ui-timepicker-div"> <div id="ui-timepicker-hours"> <div class="ui-timepicker-header ui-widget-header ui-helper-clearfix ui-corner-all"> <div class="ui-timepicker-title">Hour</div> </div> <table class="ui-timepicker"> </table> </div> <div id="ui-timepicker-minutes"> <div class="ui-timepicker-header ui-widget-header ui-helper-clearfix ui-corner-all"> <div class="ui-timepicker-title">Minutes</div> </div> <table class="ui-timepicker"> </table> </div> </div>

  • c++ multithread array

    - by user1731972
    i'm doing something for fun, trying to learn multithreading Problems passing array by reference to threads but Arno pointed out that my threading via process.h wasn't going to be multi-threaded. What I'm hoping to do is something where I have an array of 100 (or 10,000, doesn't really matter I don't think), and split up the assignment of values to each thread. Example, 4 threads = 250 values per thread to be assigned. Then I can use this filled array for further calculations. Here's some code I was working on (which doesn't work) #include <process.h> #include <windows.h> #include <iostream> #include <fstream> #include <time.h> //#include <thread> using namespace std; void myThread (void *dummy ); CRITICAL_SECTION cs1,cs2; // global int main() { ofstream myfile; myfile.open ("coinToss.csv"); int rNum; long numRuns; long count = 0; int divisor = 1; float holder = 0; int counter = 0; float percent = 0.0; HANDLE hThread[1000]; int array[10000]; srand ( time(NULL) ); printf ("Runs (use multiple of 10)? "); cin >> numRuns; for (int i = 0; i < numRuns; i++) { //_beginthread( myThread, 0, (void *) (array1) ); //??? //hThread[i * 2] = _beginthread( myThread, 0, (void *) (array1) ); hThread[i*2] = _beginthread( myThread, 0, (void *) (array) ); } //WaitForMultipleObjects(numRuns * 2, hThread, TRUE, INFINITE); WaitForMultipleObjects(numRuns, hThread, TRUE, INFINITE); } void myThread (void *param ) { //thanks goes to stockoverflow //http://stackoverflow.com/questions/12801862/problems-passing-array-by-reference-to-threads int *i = (int *)param; for (int x = 0; x < 1000000; x++) { //param[x] = rand() % 2 + 1; i[x] = rand() % 2 + 1; } } Can anyone explain why it isn't working?

  • C code to round numbers

    - by webgenius
    Is there any way to round numbers in C? I do not want to use ceil and floor. Is there any other alternative? I came across this code snippet when I Googled for the answer: (int)(num < 0 ? (num - 0.5) : (num + 0.5)) The above line always prints the value as 4 even when float num =4.9. Please suggest a solution.

  • Specify a base classes template parameters while instantiating a derived class?

    - by DaClown
    Hi, I have no idea if the title makes any sense but I can't find the right words to descibe my "problem" in one line. Anyway, here is my problem. There is an interface for a search: template <typename InputType, typename ResultType> class Search { public: virtual void search (InputType) = 0; virtual void getResult(ResultType&) = 0; }; and several derived classes like: template <typename InputType, typename ResultType> class XMLSearch : public Search<InputType, ResultType> { public: void search (InputType) { ... }; void getResult(ResultType&) { ... }; }; The derived classes shall be used in the source code later on. I would like to hold a simple pointer to a Search without specifying the template parameters, then assign a new XMLSearch and thereby define the template parameters of Search and XMLSearch Search *s = new XMLSearch<int, int>(); I found a way that works syntactically like what I'm trying to do, but it seems a bit odd to really use it: template <typename T> class Derived; class Base { public: template <typename T> bool GetValue(T &value) { Derived<T> *castedThis=dynamic_cast<Derived<T>* >(this); if(castedThis) return castedThis->GetValue(value); return false; } virtual void Dummy() {} }; template <typename T> class Derived : public Base { public: Derived<T>() { mValue=17; } bool GetValue(T &value) { value=mValue; return true; } T mValue; }; int main(int argc, char* argv[]) { Base *v=new Derived<int>; int i=0; if(!v->GetValue(i)) std::cout<<"Wrong type int."<<std::endl; float f=0.0; if(!v->GetValue(f)) std::cout<<"Wrong type float."<<std::endl; std::cout<<i<<std::endl<<f; char c; std::cin>>c; return 0; } Is there a better way to accomplish this?

How do i write this 'string' data to an image file (and other binary files)

  • XSLT 2.0 Header Leaks into Transformed XML

    - by user1303797
    First, a thank you in advance. Second, this is my first post so apologies for any errors or wrongdoings. I am a noob w/ xml and xslt, and can't seem to figure this out. When I transform some xml using xslt 2.0, some of the headers from the xslt leaks into the new xml. It doesn't seem to do it in xslt 1.0 (granted the xslt is a little different). Here is the xml: <?xml version="1.0" encoding="ISO-8859-1" ?> <xml_content> <feed_name>feed</feed_name> <feed_info> <entry_1> <id>1</id> <pub_date>1320814800</pub_date> </entry_1> </feed_info> </xml_content> Here is the xslt: <xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns="http://www.w3.org/TR/xhtml1/strict"> <xsl:output method="xml" indent="yes" /> <xsl:template match="xml_content"> <Records> <xsl:for-each select="feed_info/entry_1"> <Record> <ID><xsl:value-of select="id" /></ID> <PublicationDate><xsl:value-of select='xs:dateTime("1970-01-01T00:00:00") + xs:integer(pub_date) * xs:dayTimeDuration("PT1S")'/></PublicationDate> </Record> </xsl:for-each> </Records> </xsl:template> </xsl:stylesheet> Here is the new xml. Look specifically at the first "Records" element. <?xml version="1.0" encoding="UTF-8"?> <Records xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns="http://www.w3.org/TR/xhtml1/strict"> <Record> <ID>1</ID> <PublicationDate>2011-11-09T05:00:00</PublicationDate> </Record> </Records>
