NEST-simulated spatial-point-neuron data visualisation

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).
