ElectrodeObject describes one or more electrode arrays in three topologies (ElectrodeLayout::Depth stereotactic shaft, ElectrodeLayout::Strip 1xN ECoG, ElectrodeLayout::Grid rows x cols ECoG) and generates CPU-side geometry that the renderer uploads as a cylinder mesh (shafts) plus a per-contact instance buffer (spheres with position, radius, RGBA colour, selected flag).

Per-contact scalar values (e.g. spectral power, evoked amplitude) are mapped to a min / max colour gradient by ElectrodeObject::setContactValues so the same primitive can show static placement and live activity. Bounding-box accessors include the contact radius so the camera framing keeps every contact visible.
