!o"id #ode"ing is the #ost ad$anced #ethod of geo#etric #ode"ing in three di#ensions. !o"id

#ode"ing is the re%resentation of the so"id %arts of the ob&ect on your co#%uter. The ty%ica"

geo#etric #ode" is #ade u% of wire fra#es that show the ob&ect in the for# of wires. This wire

fra#e structure can be two di#ensiona"' two and ha"f di#ensiona" or three di#ensiona".

ro$iding surface re%resentation to the wire three di#ensiona" $iews of geo#etric #ode"s #akes

the ob&ect a%%ear so"id on the co#%uter screen and this is what is ca""ed as so"id #ode"ing.

!o"id #ode"ing is one of the #ost i#%ortant a%%"ications of the C* software and it has been

beco#ing increasing"y %o%u"ar of "ate. The so"id #ode"ing C* software he"%s the designer to

see the designed ob&ect as if it were the rea" #anufactured %roduct. +t can be seen fro# $arious

directions and in $arious $iews. This he"%s the designer to be sure that the ob&ect "ooks e,act"y as

they wanted it to be. +t a"so gi$es additiona" $ision to the designer as to what #ore changes can

be done in the ob&ect.

The co#%utationa" as%ects of so"id #ode"ing dea" with efficient data structures and a"gorith#s'

and benefit fro# recent de$e"o%#ents in the fie"d of co#%utationa" geo#etry. -fficient

%rocessing is essentia"' because the co#%"e,ity of industria" #ode"s is growing faster than the

%erfor#ance of co##ercia" workstations. Techniues for #ode"ing and ana"y/ing surfaces and

for co#%uting their intersections are i#%ortant in so"id #ode"ing.ra%hic userinterface (+)

techniues a"so %"ay a crucia" ro"e in so"id #ode"ing' since they deter#ine the o$era"" usabi"ity of

the #ode"er and i#%act the user3s %roducti$ity. There ha$e a"ways been strong sy#biotic "inks

and o$er"a%s between the so"id #ode"ing co##unity and the co#%uter gra%hics co##unity
