skydome with larger picture

[agx]

I've asked on #irc and searched forum before post this.

I've a rendering problem with skydome when the texture is bigger then 1024px. I've used Ozone3d Caps viewer to check my openGL implementation and it says that it support 2048.

The problem is here:
http://imagebin.ca/view/nTSEeLKt.html
that's the top part.

And this is the offending code:

Code: Select all

#include <irrlicht.h>
using namespace irr;
using namespace core;
using namespace scene;
using namespace video;
using namespace gui;

IrrlichtDevice *videodevice = NULL;
IVideoDriver* videodriver = NULL;
ISceneManager* scenedriver = NULL;
IGUIEnvironment* guidriver = NULL;


class CustomEventReceiver : public IEventReceiver {
public:
   virtual bool OnEvent(const SEvent &event) {
      if (event.EventType == irr::EET_KEY_INPUT_EVENT&& !event.KeyInput.PressedDown) {
         switch(event.KeyInput.Key) {
            case KEY_ESCAPE: {
               videodevice->closeDevice();
            }
         }
      }
      return false;
   }
} eventreceiver;

	
void initialize_irr_devices(void) 
{
	videodevice = createDevice( 
                video::EDT_OPENGL,        
                dimension2d<s32>(640, 480), 
                // pixel depth
                16,
                // fullscreen

                false, 
                // eventReceiver
                &eventreceiver
                );
   if (!videodevice) {
      printf("[FATAL ERROR] unable to initialize videodevice");

   }	
   // Hide cursor
   videodevice->getCursorControl()->setVisible(false);
}

void destroy_irr_devices(void)

what happens to the 2048 image when you convert it to jpg again or other format?

And what happens to the 1024 image when you resize it to 2048?

still same problem?

will test tonight when back home from work

i converted the original 1024x1024 jpg in 2048x1024 and 2048x2048 in jpg, png and tga format

the problem persist with all the images in any format >1024
