Opeis nalaganja sestava

 == Sestavljanje, materiali, transformacije ==
+
+V formatu STL ni možno nastavljati barve. Če želimo posameznim delom nastaviti barvo
+lahko to storimo tako, da naložimo vsak kos posebej in mu nastavimo material. 
+Če sestavavljamo modele z uporabo več enakih kosov je ugodno, da naložimo le
+osnovne dele, ki jih potem kopiramo in prestavljamo po prostoru in tako sestavimo
+celoten sestav. Nalaganje posameznih modelov je asinhrono, kar pomeni da se hkrati
+nalagajo in ni zagotovljen vrstni red. S takim načinom prenašanja modelov do
+brskalnika se čas do prvega prikaza sestava skrajša. Je pa zaradi tega potrebno
+nekoliko več programiranja transformacij in kopiranje položajev točk. Zmanjša 
+se tudi poraba pomnilnika v brskalniku, kar omogoča hitrejše obračanje sestava.
