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();
   
   
    
   }
   }
