FORM / FORCE / SPACETIME

Web sandbox.

Your web, from every angle. Pull its threads, change its load, or explore the geometry of gravity.

AN ILLUSTRATIVE TENSION NETWORKFIXED-STEP SIMULATION

Preparing the 3D web…

Change one thing. See what moved.

Keep a reading, then change gravity, load or a support. The previous numbers stay fixed.

Fixed supports

Move a support.

Drag its letter in the drawing, or adjust it with the buttons.

Keep the experiment.

Save the controls for your next visit or download the current drawing. Saved presets reset dragged supports.

Rotate to inspect the web. Switch to Pull web to move a strand or support.

Built on tension-only compliant distance constraints. Moving a support changes the geometry; the solver redistributes extension. It does not model real spider silk, adhesive attachment, rupture, or safe human loads.

The person behind the project

A note from Luis.

Physics, geometry, nature and space are connected parts of my curiosity. This bench turns those interests into operable models: a tension network, an emergent pattern field and central-gravity trajectories. Drawing and color expose quantities; the model notes explain their limits.

Who it helps

Curious people who want to change a condition and understand its consequence.

Try this

Probe a strand and pin a reading. Change the load and compare. In the other studies, paint a seed or adjust the golden velocity arrow.
