frame my sketch right? translate confuses me maybe
Oct 15th, 2009, 8:35am  
i think i get why it's doing this, the sin thing is around 0, but i can't figure out how to push this thing over and back so i can see it all. any tips?









float a=0;

void setup(){
 size(600,600,P3D);
 background(0);

}
void draw() {
  background(random(60),50,0);
 

for(int i=0;i<100;i++) {
 translate(1200,0,-1200);
 noStroke();
 fill(255,100,100,100);
 sphereDetail(10,10);
 sphere(100);
 translate(sin(i*10),50,-500);
 rotateY(a);
a+=0.00001;
 
}
translate(300,-900,-300);

}








thanks!

remember that there is a push / pop built into draw(); ... so your translations that occur at the end of the loop (after sphere rendering) won't do anything because the matrix pops back immediately after...and the translation you have at the start of your for() loop will be cumulative (and huge!) because there's no push/pop in that loop.
