I know this is quite an old problem, but anyone have a solution to it?

Using the bird class from the examples in 3D > transform > birds,
would this be the correct way to do it?
currently experimenting with it and apparently no birds are coming out ...

1.   columns = a.width / cellsize;  // Calculate # of columns
     rows = a.height / cellsize;  // Calculate # of rows
        image(a, 75, 50,width/2,height/1.5);
       for ( int i = 0; i < columns; i++) {
       // Begin loop for rows
       for ( int j = 0; j < rows; j++) {
         int h = i*cellsize + cellsize/2;  // x position
         int v = j*cellsize + cellsize/2;  // y position
         int loc = h + v*a.width;  // Pixel array location
         float r = red(a.pixels[loc]);  // Grab the color
         float g = green(a.pixels[loc]);
         float b = blue(a.pixels[loc]);
         if ((r+g+b)= 0){
   
           birdCount =k;
               birds[k] = new Bird(h, v,
               0, random(5, 30), random(5, 30));
         x[k] = random(20, 340);
         y[k] = random(30, 350);
         z[k] = random(1000, 4800);
         rx[k] = random(-160, 160);
         ry[k] = random(-55, 55);
         rz[k] = random(-20, 20);
         spd[k] = random(.1, 3.75);
         rot[k] = random(.025, .15);
               birdCount++;
         }
       }
       }
   

Hi guys,

So basically I created a planet class using
    planet_texture = TextureIO.newTexture(new File(dataPath(fileName)), true);
to texturise the planet and I would like to create a fireball glow effect.
how should I go about doing it ?
I tried tint and some basic glow effects though, they are not really effective...

1. class Planet {
   
   PGraphicsOpenGL pgl;
   
   GL gl;
   
   GLU glu;
   
   GLUquadric mysphere;
   
   Texture planet_texture;
   
   String fileName;
   
   float r;   //Sized to fit the texture (2048 x 1024)
   
   
   
   Planet(String pic, float radius) {
   
     r = radius;
    
     fileName = pic;
    
     pgl = (PGraphicsOpenGL) g; 
   
     gl = pgl.gl; 
   
     glu = pgl.glu;
   
     mysphere = glu.gluNewQuadric();
    
     glu.gluQuadricDrawStyle(mysphere, glu.GLU_FILL);
   
     glu.gluQuadricNormals(mysphere, glu.GLU_NONE);
   
     glu.gluQuadricTexture(mysphere, true);
   
     try {   
   
       planet_texture = TextureIO.newTexture(new File(dataPath(fileName)), true);
   
         /*  http://apod.nasa.gov/apod/image/0203/earthtruecolor_nasa_big.jpg */
   
     } 
   
     catch (IOException e) {       
   
       println(e);
     }
   
   }
   
   void draw() {
   
     pgl.beginGL();
   
     gl.glPushMatrix();
   
     planet_texture.enable();
   
     planet_texture.bind();
   
     glu.gluSphere(mysphere, r, 40, 40);
   
     planet_texture.disable();
   
     gl.glPopMatrix();
   
     pgl.endGL();
   
   
    
   }
   }

Anyone that can enlight me the problem to this code?
was there a problem placing the openGL varibles inside the class?
and furthermore, for the filename part, is it do-able in this current method?
whereby I use a string to get the input(eg. venus.jpg) and place it under the
earth = TextureIO.newTexture(new File(dataPath(println fileName)) part.

Thanks in advance for any replies~!
