we try to apply loop to rotate the points from 1 degree to 360 degree :

curently we apply rotation and geneate 360 differnt images by changing the value of theta 1,2,3...360 one by one like :

theta= 45;
R=[cosd(theta) -sind(theta) 0;
 sind(theta) cosd(theta) 0;
 0 0 1];
points = [0 0 0;
    15 0 0;
    30 0 0;
    45 0 0;
    60 0 0;
    ];
rotatedPoints = points * R;

now we want to apply loop to rotate the points that generate 360 rotated images in one execution of rotation function,any sugestion will be highly appreciateable thanks

  drawnow
