Im trying to  display text using  Print3D function. so i just add following lines into my program and also added Image.cpp file into Simplecube.mmp file

 


const char c_szImageTexFile[] = "Image.pvr";



void CSimpleCube::AppInit( void )


{

.....................

....................


m_Print3D.SetTextures(0,iScreenWidth,iScreenHeight, bRotate = false);



PVRTTextureLoadFromPVR(c_szImageTexFile, &m_ui32Texture);


}

 


void CSimpleCube::AppCycle()


{


...........

...........

 


glEnable(GL_TEXTURE_2D);



m_Print3D.DisplayDefaultTitle("IntroducingPVRTools", "Description", ePVRTPrint3DLogoPVR);


m_Print3D.Print3D(8.0f, 30.0f, 1.5f, PVRTRGBA(64, 64, 170, 255), "example");



m_Print3D.Flush();


 

}

 

this is basically a Nokia symbian opengles example program (simplecube). here i trying to implement powervr coding to  display text reference one of powerVR example (Introduction to PVRTools).

 

After compile the code program can install successfully into phone.But when i try to run the program in my Nokia N95 only Powevr logo is displaying.but the text is not display. I added image.cpp file in my source folder. the example coding usage pvrshell. but i don't using pvrshell headers files.So above lines is enough for display text. or any other configaration needed?

 

I think, my program can't load the texture(image.pvr). but any other way to load this texture use my above codestyle..

 

So plz help me about this isssue...

 

Thanks

Hello…

 

Untill there is no response abt this issue..I m desperately waiting for usefull comments/response to solve this problem.... after some examination Im little bit sure only following  lines is enogh to display text and even do need image.pvr and c_szImageTexFile, &m_ui32Texture to display only fonts/texts.. 

 


m_Print3D.DisplayDefaultTitle("IntroducingPVRTools", "Description", ePVRTPrint3DLogoPVR);


m_Print3D.Print3D(8.0f, 30.0f, 1.5f, PVRTRGBA(64, 64, 170, 255), "Hello");



m_Print3D.Flush();





Here, even logo is displaying but still text not display..what is the problem in my program?

 

Plz suggest me ...

 

 

Thanks

Hi,

 

I modified Nokia's SimpleCube example in a very similar way to you and can see the text and logo.

 

Code:
void CSimpleCube::AppInit( void )
{
....
       m_Print3D.SetTextures(0, iScreenWidth, iScreenHeight);
}
 
void CSimpleCube::AppExit( void )
{
        m_Print3D.ReleaseTextures();
}
 
void CSimpleCube::AppCycle( TInt aFrame )
    {
....
    m_Print3D.DisplayDefaultTitle("IntroducingPVRTools", "Description", ePVRTPrint3DLogoPVR);
    m_Print3D.Print3D(8.0f, 30.0f, 1.5f, PVRTRGBA(64, 64, 170, 255), "example");

    m_Print3D.Flush();
}

 

The only difference is my call to SetTextures.

 

Thanks,

Thanks Scott...but i have already add SetTextures in my coding(plz see my1st post) and also noted im trying to implement this text coding using Artoolkitplus s60 for Augmented Reality where camera is on.  
 


I tried to follow your way to add SetTextures..

 

m_ Print3D.SetTextures(0,iScreenWidth,iScreenHeight);

 

 

but result is same...only logo display but text not display yet....but i want to display the text...

 

so, how we can solve this?plz suggest me..

 

Thanks...

The above code snippets were the only changes I made to simplecube to get print3D to work. If you send your code to devtech@imgtec.com we can take a look and compare it with my changes to see if we can figure out your problem.
