i'm trying to create a 3d stamping program where stamp objects rotate around a globe according to where ever you originally stamped them. the globe rotates if you hold tab and drag and moves if you hold shift or alt and drag. I got the stamps to move along with the globe, but i cant get them to rotate properly. they seem to all be rotating at different angles. This is my code:

import processing.opengl.*;


PImage tex;
float rotx = PI/4;
float roty = PI/4;
float rotz= PI/4;
float moveX;
float moveY;
float moveZ;
int counter=1;
boolean press;
PImage b;
backdrop Clouds;
world World;
Stamp[] stamps;
PImage[] images;
