it uses the matrix effect
it involves cubes

give it a couple of seconds to normalize

*glaux needed*

Are those cubes or 6 quads? (per box)

they were inteded to be cubes but two of the sides appear to be jutting out (i think it has to do with copying the texture)

Put your name into the middle box, then output the screen to a whole bunch of bmp's, and then make it into a gif...crazy cool avatar.

Good job. I'd give you bits btw, but I don't think that you care.

Hard? Care to share?

not hard...
i think he's using
code:
glCopyTexImage2D

to intialize his moving texture... (not sure =/)
am i right catalyst?

ya that what im using
i just draw out the matrix effect
grab the screen into a texture
clear the screen
draw the cubes using that texture
swap buffers

yes i thought so...Very Happy but that matrix effect that your makin with the particle engine is nice... i gotto learn how to use a particle engine...

NUM_LETT needs to be defined
its the length of the letter trails


code:
float RandomNumP ()
{
return (((float)rand() / (float)(RAND_MAX)));
}

float RandomNum ()
{
return (((float)rand() / (float)(RAND_MAX))*2)-1;
}


code:

class matrixLetter
{
    public:

    float tX1[NUM_LETT],tX2[NUM_LETT],tY1[NUM_LETT],tY2[NUM_LETT];
    bool hLight;
    float x,y,z;
    float xv,yv,zv;
    float sizeX,sizeY;
    int i;
   
    void InitLetter (float l1,float l2,float X,float Y,float Z,float SIZE)
    {
   
    for (i=0;i<NUM_LETT;i++)
    {       

    tX1[i]=(l1)/16;
    tY1[i]=(l2+(float)i)/16;
   
    tX2[i]=((l1+1))/16;
    tY2[i]=((l2+1+(float)i))/16;
    }
   
    x=X;
    y=Y;
    z=Z;
    sizeX=SIZE;
    sizeY=SIZE*1.5;
   
    }
   
    void InitVect (float X,float Y,float Z)
    {
    xv=X;
    yv=Y;
    zv=Z;
   
    }
   
   
    void Reset()
    {
    x=RandomNum()*3;
    y=RandomNum()*2+5;
    z=-6;//-RandomNumP()*-5;
   
    yv=-0.01+RandomNumP()/-100;
   
    }
   
    void RunLetter()
    {
    x+=xv;
    y+=yv;
    z+=zv;   
   
    if (y<-4)
    {
       Reset();
    }
   
    }
   
    void DrawLetter ()
    {
     RunLetter();
     
     for (i=0;i<NUM_LETT;i++)
     {       
     glColor4f (1,1,1,(NUM_LETT-(float)i)/(float)NUM_LETT);

     glTexCoord2f(tX1[i],tY2[i]);
     glVertex3f (x-sizeX,y+sizeY+(sizeY*2*i),z);
 
     glTexCoord2f(tX1[i],tY1[i]);
     glVertex3f (x-sizeX,y-sizeY+(sizeY*2*i),z);
 
     glTexCoord2f(tX2[i],tY1[i]);
     glVertex3f (x+sizeX+0.021,y-sizeY+(sizeY*2*i),z);
 
     glTexCoord2f(tX2[i],tY2[i]);            
     glVertex3f (x+sizeY,y+sizeY+(sizeY*2*i),z); 
     
     }

    }

};

is that a particle engine?!
