; Rotate around x-axis
|

; Y = Y * COS(xang) - Z * SIN(xang) / 256
|

; Z = Y * SIN(xang) + Z * COS(xang) / 256
|

;
|

; Rotate around y-axis

; X = X * COS(yang) - Z * SIN(yang) / 256
|

; Z = X * SIN(yang) + Z * COS(yang) / 256
|

;
|

; Rotate around z-axis
|

; X = X * COS(zang) - Y * SIN(zang) / 256
|
||
; Y = X * SIN(zang) + Y * COS(zang) / 256
|
||
;
|

; Divide by 256 coz we have multiplyd our sin values with 256 too.
|

; This example isn't too fast right now but it'll work just fine.
