Visualization of Neuron Data

The Institute of Physics of São Carlos has generated data on the magnetic field around a neuron. The purpose of this work is to create a system to visualize the variety of data generated.

The system uses a software called VTK (Visualization Toolkit). It provides an easy way to create 3D graphics.

Currently, the system exists as small pieces of programs that visualize the data in some manner. This way, the physicists can tell us which programs are more useful for them.
Some images generated by the programs
 
 
Image generated by the program neuron_vet. This program visualize the vectors of the magnetic field around the neuron. It's important to note that this program and the another s shown in this page allow the user to rotate and scale the images.
Another image generated by the program neuron_vet.
Image generated by the program neuron_sph. This program visualize the vectors of the magnetic field around the neuron in a different way. It creates a sphere around the neuron and the vectors that have their origin on that sphere are visualized. The number of the points on the sphere and the radius of the sphere can be modified (not interactively, but in the future it will be)
Another image generated by the program neuron_sph.
Image generated by the program neuron_cut. This program visualize the intensity of the vectors of the magnetic field on a plane that cuts the neuron (actually there are three plane, one in each axis. In the future, it will be only one plane that you can controll interactivelly)
Another image generated by the program neuron_cut.
More things to do...
 
Now we are working in a way to visualize the lines of the magnetic field (streamlines).

We are also studying a way to allow interaction.
