NURBS

Nqkoi sluchaino da znae kude iz [censored] Inet chovek moje da nameri matematicheski aparat za tova kak se izchislqvat obemi na bazata na nqkakuv NURBS model? TIA

Не съм срещал конкретно за NURBS, но има един автор, който преди години бе писал статия за смятане на геометрични характеристики за всяка една от основните схеми за тримерно моделиране.
Пращам ти списъка. Натък търси или по авторите, или по списанията.
