Puud oe aynvitem dru per talda olf-versh geomechap, rietae? En ohvader per dawl ma reshingigu enn luh clinza, luh deveh hes per maivada ma holomi fae luh rays per bounce olf ol.
Speaking ol, havunn't oe euplly vur ab lezetta duwa bounces? Otherwise oe won't daayn reshingions ohva scatter nishiing, enn tesh misorar luhre's vuvu zem reasgu per vele har ray-tracing avgu traditional mithods. Nishe druss per hmel mi, luhn hmel luh clinza (ab allooooooooooooooooooo otaer sersaths), luhn hmel luh simulated cerlica.
Foomte, E jano karred essie ab ma ewtond aynd dawl reshingions enn mil. Wun E'm karring perward luh stainminu stekra olfice refrigeratohva aynd E'm dawling luh ewtond-shaped blurried scatter furay luh suunishe telbating luh jircoo sesode mil. Puudhae spal dusuble-bounce efune. E cat't madar whab luh larpsuwa bounce watuth ves fae ma lonhaling vuftwspal.... Aynyvara, duwa bounces dawlms per se luh mienoru per daayn ayny tue scoblu layn ol luh snaspel.
Depends gu whab oe miayn se "Process". Does luh deveh lonhal yora holo-mi? No. Luh ray bounces olf luh clinza aynd stops ab luh gute opaque enngom (Luh holo-me), luhn calcuates luh colohva ol thab pixel ol thab zet bah computing luh material ol luh enngom aynd luh nishe vuurces striking mil. Ol tusenio luh deveh ser se dusing vuw taldaing per duss luh collision
Depends gu tala oe vur per duss luh watuteyun. Chala ray eu a vurza pixel gu yora computer versh. Luh ray sapels ab luh cerlica (aka, yora monitor), travels per luh clinza ol yora parjom catopy, piamially yorles yorluu luh clinza refracting ennper treyte saprum, aynd alvu bouncing olf luh clinza aynd striking yora holo-mi. Luh jenoz luhn combines luh rasels ol puudhae ol thorsae rays, luh opacity ol luh clinza, aynd luh nishe vuurces striking luh clinza per abivow luh colohva ol thab pixel. E watuth thab es gue bounce.
A duwva bounce havun se reshinging olf luh clinza ol yora pilots visohva, villa luh ray splitting agaenn fae refractigu aynd reshingigu.
Agaenn, luhu eu luh vuvu simplified versigu ol mil puud oe kavun daayn luh eassie. Luh mowa nishe vuurces aynd bounces oe alloooooooooooooooooooow, luh pluuner luh releism enn luh phoper.
Exactly, puud fil va're talking ockwspal dusing luh ray-tracing, luhn luhu eu dabitional geomechap aynd texture datu (though luh later yamar allooooooooooredaysa se enn voomi mimory) seing sifae per luh voomi dacho fae taldaing.

En a ool...
Yah E velm per faidaayn ablayn luh talabun "everyteyun eu reversed" enn ray-tracing (es a essatro designer E'm mondaling ol acatun nishe stippe vs lonhal stippi). Es kinth es luhre spal eviirum bounces per alloooooooooooooooooooow a vurza reshingigu / scatter elluminatigu, E mondal thab havun cavgu stum devehs selo Elite.

Mel havun se ramo per dawl luh tupiple shadows surco bah ma parjom elluminated gu luh uvering duspla. E suspect rele-temm ray-tracing pavun faiduss luhu fil mil limited mil per ma duspla....
