Nvidia PhysX?? - 12-06-08, 16:29


Para pengembang game sepertinya mulai kedepan akan mendapatkan kemudahan dalam membuat dunia-dunia virtual yang semakin nyata dan mengisinya penuh dengan kehidupan. Hal ini diperkuat dengan sebuah kerjasama antara Nvidia dengan NaturalMotion untuk memperkuat teknologi PhysX mereka.

“Kita sangat terkesan dengan komitmen Nvidia untuk mendorong teknologi physics ke tingkat performa dan keaslian yang lebih tinggi.” Kata TOrsten Reil, CEO dari NaturalMotion. “Teknologi PhsyX milik Nvidia menyediakan sebuah dasar yang kuat dan murni untuk algoritma advanced animasi karakter. Melalui kolaborasi yang intim, kita dapat membantu para pengembang game untuk menghadirkan karater yang lebih interaktif dan asli kedalam jangkauan game yang lebih luas.”

Teknologi yang sedang mereka kembangkan akan menghadirkan interaksi yang lebih bervariasi dan nyata.Karakter dapat berinteraksi lebih baik dengan lingkungannya, layaknya orang beneran. Wow, sebuah teknologi yang sangat berguna demi masa depan gaming.

Ageia PhysicX VS Havok

klo console game X360 sih kebanyakan make Havok, dan new physic engine Euphoria
klo di PC, Havok sekarang dipegang INTEL ama AMD Radeon

so?

Dari hasil baca baca gw lebih dari 20 artikel, gw menyimpulkan kalo Natural Motion DNM - Euphoria, itu physics AI sedangkan Havok Physics itu engine.

DNM - Euphoria itu kayak list excel yang isinya perhitungan kalkulatis bagaiman sebuah karakter akan bereaksi terhadap lingkungannya. Karakter yang dimaksud disini bisa semua macam benda. Jadi Euphoria itu AI nya doang.
Havok bertugas untuk memberitahu Euphoria bagian mana yang harus di emulasikan physicsnya, Euphoria akan menghitung benda itu harus bagaimana harus bertindak sesuai dengan trigger ( statement benda ), tindakannya lalu di emulasikan oleh engine Havok.

Untuk lebih mudahnya, bayangkan ini :
Havok = foobar
Euphoria = AsioFoobar / Skin template.

Euphoria DNM itu cuma addon untuk system phisics. Sementara kalkulasi physics tetep dilakukan oleh Havok Engine. Euphoria itu berat, dan bahkan komputer sekarang belum mampu untuk merender benda segitu banyak yang di emulasikan pake euphoria, makanya untuk console, fitur2 euphoria AI akan di 'optimize' ( baca : dipotong yang nggak perlu ). Begitu juga untuk PC, sampai saat ini. Euphoria + Havok baru bisa jalan optimal kalo hardware nya emang udah ada instruksi untuk itu.

Kalo di GPU, gw kurang tau, tapi kalo di CPU, itu SSE4. Di GPU kayaknya pake chip x86 khusus. Jadi sebenernya kalo mau, AGEIA juga tinggal download aja itu Euphoria DNM. Terus gabungin dah sama AGEIA.

Havok ( tanpa euphoria ) itu bagus soalnya lightweight. AGEIA itu nggak masuk akal, perlu hardware khusus. Tapi bagaimanapun soal realisme, ternyata Ageia lebih baik ketimbang Havok ( tanpa euphoria ). Nah setelah ditambah euphoria ini, nggak tau deh. Blom ada artikel yang membandingkan langsung kedua nya. cmiiw.

Tapi yang jelas jadi sama sama berat, CPU intensive.

Jadi Natural Motion bener bener nggak ada hubungannya sama Havok dan Ageia. Natural Motion ( pencipta Euphoria ) itu cuma ngasih list bahwa benda benda itu harusnya bertindak seperti "ini" dalam sistem physics. Benda A beda dengan benda B, dan benda B beda dengan benda C dan E. Dia cuma AI doang bukan engine.

Yang menonjol dari Euphoria, itu perubahan sifat yang ditunjukkan pada ragdoll physics, dan physics material lain karet, kayu, besi, beton, plastik, sampai jelly.

sori sama dengan post ini :
Physic integrated pada HD4800 adalah: Havok

ada yg udah coba 177.39 + PhysX drivers 8.6.012 ??
baca di guru3d ktanya gpu nvdia diatas seri 8, bisa ngaktifin fungsi physx di GPU
Quote:
As you guys likely know NVIDIA issued a new PhysX supporting driver to the press, which (driver) actually already got leaked.
This driver will enable and allow a significant set of Physics functions to be ran over the GPU. Now I just put this quickly to the test, though in very early stages testing I must say it pushes out some pretty interesting results.
First off, there are some new included demos in the additional PhysX software you need to install, which really work out well. This trick is however to get some software going with this new feature. Currently I am testing a GeForce 9800 GTX Black Edition from XFX; tried out the new PhysX driver and installed a press version NVIDIA PhysX software build on there (not available just yet).
Though within games offloading PhysX to the GPU would take a toll on your framerate there seems to be one application benefiting from this new option greatly .. 3DMark Vantage.
Let me show you a test run with the new GeForce 177.39 driver and then with the NVIDIA PhysX (8.06.12) driver installed:
  • PhysX driver on: Overall Performance score 7493 - GPU score 6029
  • PhysX driver off: Overall Performance score 5823 - GPU score 6022
It causes a bit of a concern as what exactly is the new score now telling us ? Definitely not GPU performance, but it does boost the overall Vantage score significantly. Looking further ahead ... If you measure game performance with PhysX enabled in a game that actually supports it, the framerate will be slower opposed to a competitor who doesn't have that function enabled/supported.
My suggestion to NVIDIA, definitely make an on/off switch in the drivers so the press can measure objectively. It's a great feature though, and I love to see this well developed and become a standard in games.
yg udah coba tolong konfirmasi nya plzz
