Entourage

Scale and life for your drawings. An image model draws the figure or tree, and Alien traces it into clean outlines, fills and hatches at true size.

Component	What it’s for
Scale figure	A person as a true-height silhouette for elevations and sections.
Scale tree	A tree silhouette at true size, in elevation or plan, with the gaps in its canopy kept.

Scale figure

scale_figure A person as a true-height silhouette for elevations and sections. Say who (“a woman pushing a pram”) and from which side. Cost: About US$0.034 per drawing; free from the cache.

Inputs

Input	Type	On the component	Default	What it does
`who`	Text	Text field	`an adult walking`	who, doing what
`height`	Number	Slider 0.3–2.5	`1.75`	figure height (m)
`view`	Text	Dropdown	`side`	which way the figure faces. One of `side`, `front`, `back`, `three-quarter`
`variant`	Integer	Slider 0–50	`0`	another drawing of the same request
`generate`	Boolean	Button	—	draw it with the image model (paid); a drawing made before comes back free
`detail`	Number	Slider 0–1	`0.5`	outline detail, 0-1
`smooth`	Boolean	Switch	on	smooth curves (off: straight segments)
`plane`	Plane	Wire	—	where the figure stands (default: the XZ elevation plane at the origin)

Outputs

Output	Type	What it gives you
`outline`	list of Curve	silhouette outlines, holes included
`fill`	list of Brep	filled silhouette
`hatch`	Data	solid hatch, for baking
`info`	Text	prompt, model, cost, scale
`image`	Text	the generated image file

How it works

Only the generate button calls the image model: a new who, view or variant waits for it; drawings made before come back free. Height, detail, smooth and plane only re-trace or re-place the drawing.
Tracing: marching squares with sub-pixel edges, small islands and gaps dropped by detail, Douglas-Peucker simplification, smooth closed curves with a polyline fallback.
A blank, cut-off or non-white drawing is redrawn once with a stricter prompt, only while Generate runs; the check uses a fixed detail so the detail slider never causes a redraw.
Stands in the XZ plane at the origin (Front view) unless a plane is wired.
Drawings are cached in <repo>/.alien/cache/graphics and saved to the asset library.

Scale tree

scale_tree A tree silhouette at true size, in elevation or plan, with the gaps in its canopy kept. Cost: About US$0.034 per drawing; free from the cache.

Inputs

Input	Type	On the component	Default	What it does
`species`	Text	Text field	`mature deciduous street tree`	kind of tree
`height`	Number	Slider 0.5–60	`8`	tree height in elevation (m)
`view`	Text	Dropdown	`elevation`	elevation or plan. One of `elevation`, `plan`
`spread`	Number	Slider 0–60	`0`	canopy width in plan (m); 0 = 0.75 x height
`variant`	Integer	Slider 0–50	`0`	another drawing of the same request
`generate`	Boolean	Button	—	draw it with the image model (paid); a drawing made before comes back free
`detail`	Number	Slider 0–1	`0.5`	outline detail, 0-1
`smooth`	Boolean	Switch	on	smooth curves (off: straight segments)
`plane`	Plane	Wire	—	where it stands (default: XZ elevation plane, or XY for plan)

Outputs

Output	Type	What it gives you
`outline`	list of Curve	silhouette outlines, canopy gaps included
`fill`	list of Brep	filled silhouette
`hatch`	Data	solid hatch, for baking
`info`	Text	prompt, model, cost, scale
`image`	Text	the generated image file

How it works

Only the generate button calls the image model: a new species, view or variant waits for it.
Elevation: sized by height, standing in XZ. Plan: sized by spread (0 = 0.75 x height), lying in XY.
Same tracing, checks, cache and asset saving as scale_figure; a detailed tree (183 loops) solves in 0.6 s.
