Hi,
I've got a probelm with the shape functions. I have a cube which is constructed of some vertices and the textures are changed over the time.  But every time the draw function is called with a newly texture-picture the used memory  increases also I just change the texturevar to point to another already loaded image. Is there a need / possibily to destroy the previous texture/shape when I change it?

Here's the code

1. 
   void draw(){
   ...
   if(frameCount%30==0){
         backimg = images[imgCounter];
         imgCounter++;
   }
   ...
2.   textureMode(NORMALIZED);
    
     stroke(0);
     strokeWeight(0.0);
    
    
       beginShape(); 
       texture(backimg);
        // -Z "back" face
       vertex( w+5, -h-5, boxdepth*times*offs, 1, 0);
       vertex(-w-5, -h-5, boxdepth*times*offs, 0, 0);
       vertex(-w-5,  h+5, boxdepth*times*offs, 0,1);
       vertex( w+5,  h+5, boxdepth*times*offs, 1, 1);
       endShape();
3. //at that point the memory use increases, but only if  the backimg var points to another new picture 
4. 
   
         ....}
