  1. Re: Overlaying 3D on live video - is texture upload really the best way?

    I don't think it's important at all. Real bottleneck is usually reliable feature detection and correspondence, following with camera 3d position restoration.

  2. Re: Image processing - Sobel filter problem (edge detection)

    Yep, you should get something like first image. Sobel doesn't do smoothing, you should get a lot of noise. You can pass through smoothing filter before edge detection filter. And don't forget fix...
  3. Re: Image processing - Sobel filter problem (edge detection)

    You should show original image if you want meaningful answer. Anyway dy seems wrong.
  4. Re: S60 3rd edition support for SVG Tiny 1.1+ profile

    I think only partially. At least some SVG Tiny were reproduced not correctly on N95.
  5. Re: How to draw/write a text usning openGL ES1.1 in Nokia Phone

    There several open sourced text/fonts libraries for OpenGL. Don't remember links now, but you can easily google for it, and check also sourceforge.net. Shouldn't be difficult to modify them for...

    Re: Augmented reality

    It depend on the implementation, but you can not have transparent background in the most of OpenGL ES implemenation (like Nokia N95)

    Re: Augmented reality

    If you only starting work with AR better start with PC application. Mobile is hard enough even without having to deal with camera and image registration.

    Re: Masking bitmaps programmatically

    Easy.
    Use
    iBitmap->LockHeap(EFalse);
    TUint8* source = (TUint8*)iBitmap->DataAddress();
    //do something
    iBitmap->UnlockHeap(EFalse);

    Where the private directory on the emulator ?

    I'm using FP1 SDK, Visual C++, and on the device application is working OK. However on the emulator app can not find some data files.
    In the pkg file I have

  11. Re: Blank screen when SimpleCube is built with vfpv2 on Nokia 5800

    The problem could be that OpenGL floating point API functions are bugged. You can test this if you use your floating point code, but convert data to fixed point only while calling OpenGL ES function...
  12. Re: Is it possible to write a 3D game engine without using OpenGL ES apis?

    No. Only if you have no OpenGL ES support.

  14. Re: Is it possible to write a 3D game engine without using OpenGL ES apis?

    Yes. Look for old nokia 3d game example, for FP1. It has source code for software renderer.

    Works fine with MR3.0 and FP1

    It may be possible in some cases with firmware replacement, if the camera hardware originally had higher resolution and resolution was reduced by manufacturer later on the firmware level.

    Re: OpenGL render to texture

    You could have some problem in initialization
    1. You should try to use the same context for pbuffer and win. Don't create pbuffer context at all, use win. What config are you using ?
    2. What param...

    Re: OpenGL render to texture

    Aha.
    You should release pbuffer after using it as texture.
    call
    eglReleaseTexImage(iDisplay, iPBuffer, EGL_BACK_BUFFER) after rendering into *windows*
    probably after eglSwapBuffers( iDisplay,...

    Re: OpenGL render to texture

    Pbuffer initialization:
    I don't think you have to actually create texture - only initialize it.
    Try instead dummy texture, without reserving videomemory
    glTexImage2D(GL_TEXTURE_2D, 0, GL_RGB, 256...

    Re: OpenGL render to texture

    IIRC eglBindTexImage should be called not during the initialization but after the rendering into texture.

    Re: OpenGL render to texture

    Where do you use eglMakeCurrent ? There is no code for rendering into pbuffer also. If you don't render anything you have nother in the pbuffer texture.

    That was discussed extensively on this forum. Search for pbuffer, viewfinder, texture etc on this forum.

    Re: Need Help with Texturing

    GLuint texture;
    glGenTextures( 2, &texture );

    Wrong size. You have buffer overflow here.
    Should be either GLuint texture[2] or glGenTextures(1, &texture );

    Advice - if you are new to OpenGL...
