They have been ignored, or old ones used instead.

• Using GPS data in Application

  - by Moka

  Hi, I want using GPS data (I got it from $GPRMC) in an desktop application(that uses from mappoint 2009). I get the latitude & longitude, but when I check these points on map, I see the result is incorrect (for example My Data is: 43.412 N, 79.369 W ; but the correct point is: 43.686 N, 79.616 W ). I guess, I must use a correction method before use; I try "Projection method" like "Miller" or "Mercator", but those aren't effective. Can anyone guide me?

• What is different about C++ math.h abs() compared to my abs()

  - by moka

  I am currently writing some glsl like vector math classes in c++, and I just implemented an abs() function like this: template<class T> static inline T abs(T _a) { return _a < 0 ? -_a : _a; } I compared its speed to the default c++ abs from math.h like this: clock_t begin = clock(); for(int i=0; i<10000000; ++i) { float a = abs(-1.25); }; clock_t end = clock(); unsigned long time1 = (unsigned long)((float)(end-begin) / ((float)CLOCKS_PER_SEC/1000.0)); begin = clock(); for(int i=0; i<10000000; ++i) { float a = myMath::abs(-1.25); }; end = clock(); unsigned long time2 = (unsigned long)((float)(end-begin) / ((float)CLOCKS_PER_SEC/1000.0)); std::cout<<time1<<std::endl; std::cout<<time2<<std::endl; Now the default abs takes about 25ms while mine takes 60. I guess there is some low level optimisation going on. Does anybody know how math.h abs works internally? The performance difference is nothing dramatic, but I am just curious!

• cocoa/c++ relative path to load resources

  - by moka

  Hi, I am currently working directly with cocoa for the first time, to built a screen saver. Now I came across a problem when trying to load resources from within the .saver bundle. I basically have a small c++ wrapper class to load .exr files using freeImage. That works as long as I use absoulte paths, but thats not very useful, is it? So basically I tried everything, putting the .exr file on the level of the .saver bundle itself, inside the bundles Resources folder and so on. Then I simply tried to load the .exr like this without success particleTex = [self loadExrTexture: "ball.exr"]; I also tried making it go to the .saver bundles location like this: particleTex = [self loadExrTexture: "../../../ball.exr"]; to maybe load the .exr from that location but without success. I then came across this: NSString * path = [[NSBundle mainBundle] pathForResource:@"ball" ofType:@"exr"]; const char * pChar = [path UTF8String]; which seems to be a common way to find resources in cocoa, but for some reason its emty in my case. any ideas about that? I really tried out anything that came to my mind without success so I would be glad about some input!

• xCode screensaver with openGL

  - by moka

  Hi, I am currently simply trying to build a simple screen saver in xcode 3.2 on osx 10.6.3 using an openGL view as described in this article: http://cocoadevcentral.com/articles/000089.php anyways even if I use the exact same code from the example all I see when testing the screen saver is a black screen. I looked in OSX Console if it tells me anything useful. the only thing I get is something like this: [0x0-0x1e01e].com.apple.systempreferences[629] System Preferences(629,0x7fff71071be0) malloc: reference count underflow for 0x20057be80, break on auto_refcount_underflow_error to debug. System Preferences[629] invalid context I have no idea what is wrong, so I would be glad if someone could tell me how to use openGL together with the screensaver template in xCode 3.2. Also, is there a way to make another target so I can preview the screensaver from within xCode? Thanks!

• Write a serverside c++/openGL App, that is accessible via JavaScript

  - by moka

  Hi, I am currently having an idea where I want to save an image from a c++/openGL application on demand from a browser. So basically I would like to run the application itself on the server and have a simple communication layer like this: JS - tell application to do calculations (and maybe pass a string or some simple data) application - tell JS when finished and maybe send a link, text or something as simple as that. I don't really have alot of experience with webservers and as such don't know if that is possible at all (it's just my naive thinking). And note: I am not talking about a webGL application, I just want to have simple communication between a c++ serverside application, and the user. Any ideas how to do that? Thanks alot!
