@urban-toolkit/autk-core / TransferFunction

Interface: TransferFunction

Defined in: transfer-function.ts:17

Configures how scalar values map to opacity.

The active mode determines which values receive higher opacity after the input values are normalized against the current transfer context.

Properties

gamma?

optional gamma?: number

Defined in: transfer-function.ts:31

Curve shaping factor; values <= 0 are clamped to a tiny positive exponent at evaluation time.

---

mode?

optional mode?: "linear" | "near-zero" | "far-zero"

Defined in: transfer-function.ts:25

Opacity mapping mode.

• near-zero: values closer to zeroCenter are more opaque.
• far-zero: values farther from zeroCenter are more opaque.
• linear: opacity increases monotonically across the dataset range.

---

opacityMax?

optional opacityMax?: number

Defined in: transfer-function.ts:29

Upper bound for output opacity in [0, 1].

---

opacityMin?

optional opacityMin?: number

Defined in: transfer-function.ts:27

Lower bound for output opacity in [0, 1].

---

zeroCenter?

optional zeroCenter?: number

Defined in: transfer-function.ts:33

Reference center used by zero-distance modes (default 0).
