This paper presents a real-time physically based platform for multi-sensory interactive simulation. This platform is centred on high quality dynamic requirements driven by the concept of instrumental in- teraction. It is oriented towards the simulation of " vis- a-vis "human- object interactive simulation for a broad range of physical phenomena, with a speci c focus on simulations with demanding capacities regarding dynamics such as tool use, object manipulation, music instrument playing, etc. The platform consists in a precisely synchronized multipro- cessor architecture extended with a DSP board used for the simulation of very reactive models. Two versions have been implemented correspon ding to specific simulation requirements : (1) a highly reactive simulator for models with strong dynamical requirements but low computation needs, such as sounding instruments ; (2) a 64 bit oating point multiprocessor architecture for large 3D models with complex interactions such as fluids, smoke, crowds.
