; Fell free to use this intro in your own distribution of KolibriOS.
; Special greetings to KolibriOS team .
; I hope because my demos Christian Belive will be near to each of You.
; Some adjustments made by Madis Kalme
; madis.kalme@mail.ee
; I tried optimizing it a bit, but don't know if it was successful. The objects
; can be:
; 1) Read from a file (*.3DS standard)
; 2) Written in manually (at the end of the code) ; now not exist

; For now correct only SSE2 and SSE3 versions. if you have older CPU
