Snow White Dining

Why This Example Exists

This is a compact visual example with enough personality to be remembered. It builds a dwarf-sized dining table with eight chairs: one larger chair for Snow White and seven smaller chairs for the dwarfs.

It demonstrates that FCS is not only formulas. It can describe a parametric scene, reuse component classes, place repeated objects, and produce a visual output.

Update note: this example now uses a warm wood material layer in Box.fcs, so the furniture has material metadata rather than only plain geometry.

Agent note: the iframe above uses the same scene JSON linked in the file list. If the embedded viewer is unavailable, use the raw HiScene file directly and open it in https://viewer.histruct.com/.

What It Teaches

gclass loads reusable component definitions.
gblock places component instances.
Parameters drive table and chair dimensions.
Local coordinate systems position and rotate objects.
layer ... material { ... } attaches PBR-style visual material properties.
One source model can produce a HiScene viewer output.

The full source places Snow White at one end, three dwarfs on each long side, and one dwarf at the far end. Box.fcs applies the warm-wood layer to the generated box faces.

Try Locally

When FLI is available, the validation loop should produce a scene from:

fli.exe site/content/knowledge-base/examples/snowwhite-dining/DiningScene.fcs

The exact scene-generation flags may depend on the local FLI version. This page intentionally records the example first; the command should be tightened once the FLI workflow is verified here.

View Output

The repository already contains expected HiScene output:

snowwhite-dining.hiscene.json

The generated HTML embeds that output through viewer.histruct.com using a share hash. This keeps the local preview working before the final public D-Zone URL exists.

Try In Golem

Future placeholder:

https://golem.histruct.com/?example=snowwhite-dining

Useful first prompt:

Make the table longer and add two more dwarf chairs. Keep the spacing readable.

Common Mistake

Rotation matters. The chairs do not only move; they must face the table. Watch the Rz(...) transforms in DiningScene.fcs.
