AGEIA PhysX PPU

[no-X]

Uvedomovat by sis mel predevsim ty, protoze tohle pocita GPU a je jen na nem jak a kolik prachovejch castic vygeneruje, ty se ti stejne jen zobrazej a zmizej, nemaj zadnej efekt na hru a co hur, i ten efekt ze ti zakrejou vyhled je odstranitelnej, protoze server (mluvim ted o online hrani) nema poneti ze nakej vybuch existuje.

Promiň, ale akcelerace particle effects je jedním z klíčových prvků, kterým se ageia pokusila prorazit. Jejich množství je totiž v současné době limitované výkonem CPU, který nestačí na generování, výpočet dráhy a pohybu tak vysokého množství objektů. Asi nemá cenu to víc rozebírat, když se to rozebíralo téměř všude...

The screenshots above reflect key physics features and functionality found in the upcoming title "Bet on Soldier". In these shots, we see some extremely detailed particle effects which involve fluids and flames. Smart particle calculations are applied to density, volume, and pressure to create new visual effects and also offer some unique gameplay options. For instance, fluid-based weapons can be used to attack an opponent hiding around corners as the stream can conform and make its way around the corner and damage those who are in the fluid's proximity.

Hardware-based physics processing represents a new trend in gaming. With hardware-based physics acceleration, games can feature dramatically more realistic real-time physics effects, including smoke, particle effects, dynamic physical motion and interaction far beyond what today’s games are capable of doing.
