Re: GCC, Switch( condition ) & Case

@Gazelle
In fact, I've made it slightly different now:


switch( Depth ){

      case 8:

        DMode = GLUT_DOUBLE | GL_COLOR_INDEX;

        break;

      case 16: /* for now fall through */

      case 24:

        DMode = GLUT_DOUBLE | GLUT_RGB | GLUT_DEPTH;

        break;

      case 32:

        DMode = GLUT_DOUBLE | GLUT_RGBA | GLUT_DEPTH;

        break;

      default:

        DMode = GLUT_DOUBLE | GLUT_RGB | GLUT_DEPTH;

     }

All we have to decide is what to do with the time that is given to us.

Effectively, second = added :p

I must not simplify cos, if some more modes are added to glut to handle RGB32, RGB24, RGB16 and color index 8 bits, I want to have just to add the correct flag to make my display mode use them.

GCC, Switch( condition ) & Case

Posted on: 2009/2/22 23:36 #625

Hi,

I encounter an error on using SWITCH/CASE C/C++ commands under GCC ... I don't understand why because I think I use correctly the functions :

Here is the error :
setup.c:104:error: expected expression before 'default'

Here is the code :


/* Cr?ation de la fen?tre d'affichage principale */

void SetDisplayMode( int Width, int Height, int Depth ){                    /* TO DO : MUST ADDED WITH TO InitDisplayMode */

  BOOL Supported;

  int DMode;

  Supported = CheckDisplayMode( Width, Height, Depth );

  if ( Supported = TRUE ){

    /* Open the screen using windowed mode */

    switch( Depth ){

      case 32:

        DMode = GLUT_DOUBLE | GLUT_RGB | GLUT_DEPTH

      case 24:

        DMode = GLUT_DOUBLE | GLUT_RGB | GLUT_DEPTH

      case 16:

        DMode = GLUT_DOUBLE | GLUT_RGB | GLUT_DEPTH

      case 8:

        DMode = GLUT_DOUBLE | GL_COLOR_INDEX

      case default:

        DMode = GLUT_DOUBLE | GLUT_RGB | GLUT_DEPTH

     }

    glutInitDisplayMode( DMode );              /* Define display mode properties */

    glutInitWindowSize( Width, Height );

    glutInitWindowPosition( 32, 32 );

    WindowID = glutCreateWindow( "AmiDARK Basic application" ); /* Create the asked window */

    if (FullSCREEN == TRUE ){

      glutGameModeString( "640x480:32" );

      glutEnterGameMode();

     }

   }

 }

Strange. not ?
Or I am wrong again ?

EDIT :
Forget, I've found the error ... default does not need "case" before ... :p

if (IsFullScreen) // best

Then you prefer IsFullScreen as bool to handle fullscreen mode state ?

@BillE
MiniGL 2.0 should be released when the Hyperion website will be back online.
(it's what Hans said on an other post I've made on amigans.net).
You should then get these files soonly.

GCC and boolean ....

Posted on: 2009/2/22 11:19 #631

Hi All,

I encounter a small issue using boolean.
Here is my code :

1st part, the main C project :


#include <gl/glut.h>



int argc;

char** argv;



#include "setup.c"

#include "camera.c"

#include "core.c"



int main( int argc, char** argv ){

  Constructor();

  SetDisplayMode( 640, 480 );

  Destructor();

  return 0;

 }

And now, part of setup.c file :


/* Variables globales au fichier lib */

BOOL FullSCREEN;

int WindowID;



/* Procedure d'initialisation de la lib DISPLAY */

void Constructor( void ){

  FullSCREEN = FALSE;

  glutInit( &argc, argv );                                       /* Initialize Glut */

/*  glutDisplayFunc( DisplayFunc ); */

/*  glutReshapeFunc( ReshapeFunc ); */

 }



/* Procedure de la fermeture de la librairie DISPLAY */

void Destructor( void ){

  glutDestroyWindow( WindowID );

 }



/* Cr?ation de la fen?tre d'affichage principale */

void SetDisplayMode( int Width, int Height ){                    /* TO DO : MUST ADDED WITH TO InitDisplayMode */

  /* Open the screen using windowed mode */

  glutInitDisplayMode( GLUT_DOUBLE | GLUT_RGBA );              /* Define display mode properties */

  glutInitWindowSize( Width, Height );

  glutInitWindowPosition( 32, 32 );

  WindowID == glutCreateWindow( "AmiDARK Basic application" ); /* Create the asked window */

  if (FullSCREEN = TRUE){

    glutGameModeString( "640x480:32" );

    glutEnterGameMode();

   }

 }

When I compile the main C file, it compiles correctly but, when I run it, it open a window and jump in fullscreen mode. It shouldn't jump in fullscreeen mode.
if I change in the SetDisplayMode() function, this line :


if (FullSCREEN = TRUE){

with :


if (FullSCREEN = FALSE){

then it run, open a window and quit correctly without using full screen mode...
Why does boolean act this way ? it should work as opposite than this . not ?

Kindest Regards,
Freddix

If course, FullSCREEN is declared as global :


int FullSCREEN;

MiniGL - Switch mode : fullscreen & windowed

Posted on: 2009/2/21 22:08 #634

Hi,

I'd like to know how we can, as simple as possible switch from these 2 modes at anytime in an OpenGL/MiniGL application ?

Can I do something like this :


/* Sauter en mode plein ?cran */

void SetFullScreenMode(){

  if (FullSCREEN = 0){

    glutGameModeString( "640x480:32" );

    glutEnterGameMode();

    FullSCREEN == 1;

   }

 }



/* Sauter en mode fen?tr? */

void SetWindowMode(){

  If (FullSCREEN = 1 ){

    glutLeaveGameMode() ;

    FullSCREEN == 0;

   }

 }

and call SetFullScreenMode to jump in fullscreen mode and SetWindowMode to jump in windowed mode ?

Kindest Regards,
Freddix.

Hi All,
does someone have any information concerning the Hyperion website ?
Few days ago a page appeared requesting user/pass now. It's directly a windows popup requesting for user
It mention that it is under "test phase" ..

Any informations ?

Thanks

@Hans :
Quote:

GlFlush() causes your program to wait until the graphics card/driver has finished processing all the commands that you just gave it. It's usually not needed. You would use it only if you want to read back the image that you've just drawn in order to use it for something (e.g., as a reflection map).

Can we render the 3D in something else than a window ? (a texture for example, this could be better for future shader use)

@Samurai_Crow:
Thank you for this link, now I understand how the function work. It work now how I expected.

Thank you.

@Shadow : I tried this without success ... nothing appear on screen ...
Is there a precise moment to display the text ?

Thank you.

I think I've understood the principle of refreshing the display now.
I'll take a look at animations ...

As I'm beginner on C/C++, I didn't found how to convert an integer into a string, because I'd like to display debug informations during my dev tests such as frame rate, etc ...
Do you have any info ?
