A computational environment in the following called Problem Solving Environment (PSE) dedicated to the analysis of tomographic images of composite materials is presented. The PSE current version is centered on reinforcement characterization and its main features are: (i) running on a desktop PC equipped with GPGPUs (General Purpose Graphical Processing Units); (ii) allowing a nonspecialist in Computer Science to define visual programs that specify a sequence of processing steps; (iii) execution times compatible with an interactive use, due to the computational processing power of GPUs; (iv) the inclusion of visualization modules and the possibility of steering the computations through parameter changes.
