I have noticed that remplacing these calls :
Math.cos(theta)
and
Math.sin(theta)
... by this kind of calls :
-Math.cos(theta % Math.PI - Math.PI)
and
-Math.sin(theta % Math.PI - Math.PI)
... the program runs about 7 times faster on my machine (i don't know why...) ! It is better than using JNI, and more accurate than using lookup tables since it works for any value.
