Matrix manipulation programs are easily developed using a visual language. For signal processing, a graph of tasks operates on arrays. Each task iterates the same code on diierent patterns tilling these arrays. In this case visual speciications of dependencies between the pattern elements are enough to deene an application. From the Array-OL language… (More)
Array-OL, developed by Thomson Marconi Sonar, is a programming language dedicated to signal processing. An Array-OL program specifies the dependencies between array elements produced and consumed by tasks. In particular, temporal dependencies may be specified by referencing elements that belong to an infinite dimension of an array. A basic compilation… (More)
The ARTiS system, a real-time extension of the GNU/Linux scheduler dedicated to SMP (Symmetric Multi-Processors) systems is proposed. ARTiS exploits the SMP architecture to guarantee the pre-emption of a processor when the system has to schedule a real-time task. The basic idea of ARTiS is to assign a selected set of processors to real-time operations. A… (More)
The ARTiS system is a real-time extension of the GNU/Linux scheduler dedicated to SMP (Symmetric Multi-Processors) systems. It allows to mix High Performance Computing and Real-Time. ARTiS exploits the SMP architecture to guarantee the preemption of a processor when the system has to schedule a real-time task. The implementation is available as a… (More)
We present a low-cost hand-based device coupled with a 3D motion recovery engine and 3D visualization. This platform aims at studying ergonomic 3D interactions in order to manipulate and deform 3D models by interacting with hands on 3D meshes. Deformations are done using different modes of interaction that we will detail in the paper. Finger extremities are… (More)
In this video, we present a hand-based device coupled with a 3D motion recovery engine and 3D visualization. This platform aims at studying 3D interactions in order to build an ergonomic 3D device for 3D scenes construction and 3D objects modeling. Possible applications are Computer Graphics and Medical Imaging.
