THE REQUEST

Equations you can touch.

Build an interactive 3D heart from supplied equations, with pulse, depth, colour and mathematically linked cross-section controls.

The agent builds the surface and its auxiliary geometry in native GeoGebra expressions, then arranges them as an interactive exhibit.

Playback and direct manipulation check 18 combinations of depth, slice position and pulse phase. The saved construction is reopened and the slice is moved again.

An editable .ggb construction, four controls and three saved views.

.ggb18 parameter states checked

About this record

External Codex-supervised controller using NorthCUA Desktop MCP tools. Tool-interface showcase, separate from native Harness Runtime demos and NorthCUA checkpoint benchmarks.

Recorded steps include observations and checks. The pulse animation is an application feature, not a measurement of model inference speed.
