this is flipbooked sequence of a Rigid Body Simulation with in Houdini using the ODE Solver..
Actually this is more of a Hybrid..using POPs, VOP POPs, SOPs, and DOPs in Houdini..
There were 2 DOP simulations used for different purposes..
The Particles were also Advected to get a specific movement.
Main intention behind this was simply my NEED to work with the ODE Solver. ODE is mainly used for Dynamics in gaming and cant work with complex geometry..So I made up a Truck (sort of :P ) using simple primitives and used that for the Dynamics..
Though ODE Solvers are much faster than Houdini's RBDs, there's a lot of difference between the accuracy and the ability to handle Complex Geometry within a simulation.
SESI implementing ODE in Houdini is awesome! Now we have a choice in case we want just a Pre-Vis or if we are working with simple Geometry types.
The simulation for DOPs took no more than 4-5 seconds per frame..(sometimes lower than this)
POPs and VOP POPs was almost realtime..
Specs:
500 different RBDs simulated together.
DOPs Sim time: 4-5 secs per frame. (max..sometimes lower than this)
which is amazingly fast considering my system configs:
2GB RAM,
intel core 2duo, 2.1GHz, 32 bit, WinXP
