cut it out, 3DModelerMan. Don't let school break bring you down.

You see my mom won't let me have an account yet.

Why the hell would anyone's mum stop them having an image hosting account? And why would she even need to know?

my mum didnt know i got an email account even when i was in primary school

The real question is 3DModelerMan a troll or just a 11 year old?

Imageshack doesn't need an account. O_o

Okay okay I just am saying I can't put up a screenshot yet, geez. Any way my gui image is pixelated when I use openGL is this a problem with my code?.

Code: Select all

//included files
#include <irrlicht.h>
#include "mast_event_receiver.cpp"
//main namspaces
using namespace irr;
using namespace core;
using namespace scene;
using namespace video;
using namespace io;
using namespace gui;
//main function
int main(int argc, char** argv)
{

//The irrlicht device
    IrrlichtDevice *device =
        createDevice(EDT_SOFTWARE, dimension2d<s32>(768, 640), 24,
/* first parameter on line specifies fullscreen*/false, false, false, 0);


    //device options
    //================================================================================
    //sets the window caption of the application
    device->setWindowCaption(L"Wolfpack");

    //================================================================================
    //Gets a pointer to the scene manager gui environment & video driver
    IVideoDriver* driver = device->getVideoDriver();
    ISceneManager* smgr = device->getSceneManager();
    IGUIEnvironment* guienv = device->getGUIEnvironment();
     //texture creation flags
    //================================================================================
    driver->setTextureCreationFlag(ETCF_OPTIMIZED_FOR_QUALITY, true);
    //gui functions
    //================================================================================
    IGUIImage* bkg = guienv->addImage(driver->getTexture("C:/Documents and Settings/Tanner/My Documents/Wolfpack/Bitmaps/Gui/main_splash_screen.bmp"),
    position2d<int>(0,0));


    //if a key is pressed then delete the splash screen

    //================================================================================
    //draw everything
    while(device->run())
    {

        driver->beginScene(true, true, SColor(0,200,200,200));

        smgr->drawAll();
        guienv->drawAll();
        driver->endScene();

    }

   //deletes the device
    device->drop();

    return 0;
}

It's really really really hard for us to tell you with out seeing what you mean... Man the feck up and just put a screenshot online, use rapidshare if you have to!

Here's the same problem I had in this image
http://static.flickr.com/88/251736142_5319379248_o.jpg
I used power of two textures and everything.

[JP]

What size is the original image you load up and what size are you drawing it on screen. Also what driver are you using?

[3DModelerMan]

My image is 768 X 768, is not scaled inside irrlicht, and I'm using openGL.

[JP]

768 is not a power of two, hence the image will be scaled up to 1024 (nearest power of two) and that will introduce artifacts.

resize your image to either 512x512 or 1024x1024.

[3DModelerMan]

Umm... what is the nearest power of two size?. And could someone show me the calculation to find out?.

[JP]

I just told you what to do.

[Dorth]

what is the calculation to find out? Are you serious?

log[base 2](size_of_texture) = exponent

you take (int)exponent and you got the lowest pow of 2

if exponent == (int)exponent then size_of_texture is already a pow of 2

if you don't want to lose details, you probably want to go to the highest pow of 2, which is (int)exponent +1

to find the closest, simply compare which is smaller, size_of_texture - 2^(int)exponent or 2^(int)(exponent+1) - size_of_texture
