"A GPU-based Method for Massive Simulation of Distributed Behavioral Models with CUDA"

Conference:
"The 22nd Annual Conference On Computer Animation and Social Agents (CASA 2009)"

The framework "BehaveRT" allows to create a simulation:
-interactive: by using the power of recent NVIDIA GPUs through CUDA;
-generalized: by choosing the most suitable plugIn or by creating custonized ones;
-renderable: by using the OpenGL VBOs (Vertex Buffer Object) the simulation is directly renderable avoiding any data transfert between CPU and GPU.

BehaveRT is described in detail in the master's degree thesis work of Bernardino Frola:
"An extendible framework for interactive simulation of massive behavioral models on GPU" - University of Salerno.

[Crazymecrazy12]

just a question: What is the render time?

[ber85it]

@Crazymecrazy12 No specific graphics engine, just OpenGL. The particles are billboards.

[abbed8]

with what language? i.e C++ or C etc.

[ber85it]

@abbed8 C++ (OpenSteerDemo as 3D environment) and Nvidia CUDA for the hardware acceleration of particles.

[abbed8]

Did you make this?

[ber85it]

@abbed8 Yes. This is a demo of my ms thesis project

[Crazymecrazy12]

@Noah1989 :o

[Noah1989]

@Crazymecrazy12 I guess it's realtime. so the render time for this was about 3:27 ;-)

@KoRMaK1 Thanks a lot

Makes sweet, complicated 3D video, then edits the video of it in Windows Movie Maker?

[michaelpmalin]

Why does this video look interlaced?

[Hionimi]

Sooo, what kind of system was used? I mean, what are the specifications?

[KoRMaK1]

@nrasandun3 Learn to program, learn inheritance and OOP for programming, and find the algorithms you need. This uses a Boids algorithm. Each particle gets some CPU time to decide where to fly based on its surroundings. So for every frame, the 130k bodies all get to "think". So that is 130k calculations right there. Sounds big, but modern graphics cards can handle it if you use something like CUDA

@bobsonenzo yes we are!
