# Interface: AssembledPart {#interface-assembledpart}


Defined in: [assemblage/assemble.ts:41](https://github.com/jbcom/lifecycle-kit/blob/074e4e7b8038d3e2de9eb44c4b5b5aee0ef02b48/src/assemblage/assemble.ts#L41)

A shape placed in depth, ready to draw.


## Properties {#properties}



### depth {#depth}


> `readonly` **depth**: `number`

Defined in: [assemblage/assemble.ts:44](https://github.com/jbcom/lifecycle-kit/blob/074e4e7b8038d3e2de9eb44c4b5b5aee0ef02b48/src/assemblage/assemble.ts#L44)

Larger is nearer. Draw ascending so near parts land on top.

### direct {#direct}


> `readonly` **direct**: `number`

Defined in: [assemblage/assemble.ts:62](https://github.com/jbcom/lifecycle-kit/blob/074e4e7b8038d3e2de9eb44c4b5b5aee0ef02b48/src/assemblage/assemble.ts#L62)

0..1 — the directional term alone, before any part occluded it.

What position against the light says on its own. Kept because it is the
honest input to a specular highlight, which cares where the light is and
not what is standing in the way.

***


### light {#light}


> `readonly` **light**: `number`

Defined in: [assemblage/assemble.ts:54](https://github.com/jbcom/lifecycle-kit/blob/074e4e7b8038d3e2de9eb44c4b5b5aee0ef02b48/src/assemblage/assemble.ts#L54)

0..1 — how much light this part catches, for shading its fill.

Includes shadow cast by the parts in front of it. This is the number a
consumer feeds to `shade`, and it is the one that should be used: the
two components are exposed separately below for tests and for a consumer
that wants to drive them independently, not because either alone is the
right thing to draw with.

***


### occlusion {#occlusion}


> `readonly` **occlusion**: `number`

Defined in: [assemblage/assemble.ts:70](https://github.com/jbcom/lifecycle-kit/blob/074e4e7b8038d3e2de9eb44c4b5b5aee0ef02b48/src/assemblage/assemble.ts#L70)

0..1 — how much of this part is covered by the parts in front of it.

Zero for the nearest part in any scene, since nothing is in front of it.
A consumer wanting a gradient fill rather than a uniform darkening drives
it from this.

### shape {#shape}


> `readonly` **shape**: [`Shape`](https://jonbogaty.com/lifecycle-kit/api/forms/type-aliases/shape/index.md)

Defined in: [assemblage/assemble.ts:42](https://github.com/jbcom/lifecycle-kit/blob/074e4e7b8038d3e2de9eb44c4b5b5aee0ef02b48/src/assemblage/assemble.ts#L42)
