About this model

This is the average T1-weighted MRI brain atlas (the same reference volume used across neuroimaging research), turned into a 3D surface. The scan's intensity values are grouped into a handful of tissue "sections," and the boundaries between them are contoured and auto-colored — so each colored shell roughly traces a different density of brain tissue.

How it was made

Volume data: the avg152 T1 MRI atlas.
Processed in Python with PyVista / VTK — quantized into sections, contoured, and colored.
Exported to a self-contained VTK.js scene that renders with WebGL — no plugins, no server, nothing to install.

Best viewed on a device with WebGL support (virtually every modern phone and desktop browser).
