NEST-simulated spatial-point-neuron data visualisation

The development of this technology was co-funded by the HBP during the second project phase (SGA1). This page is kept for reference but will no longer be updated.

Complementary to other viewers and visualization implementations for NEST simulations, this technology offers a rendering of activity and membrane potentials in a neural network simulated with NEST.

A prototypical implementation exists that is based on vtk, the widely-used visualisation toolkit. This implementation can be generally run by computational neuroscientists on their workstations, imposing only moderate hardware requirements. Experiments using rendering on high-performance computing infrastructure were successful.

The results indicate that this component is extensible towards large-scale simulations that require HPC resources and thus produce large output data. The hi-fidelity rendering used in this case provides very high quality images that may be suitable for publications (Proof of concept image below).
