Properties

defaultValue?

optional defaultValue?: string | number

Default value to use when the source attribute is missing from node data. For size=1: a number For size=4 with normalized: a CSS color string (e.g., “#ff0000”)

---

name

name: string

Defined in: packages/sigma/src/rendering/nodes/types.ts:67

size: 1 | 2 | 3 | 4

Defined in: packages/sigma/src/rendering/nodes/types.ts:72

Number of components (e.g., 1 for float, 2 for vec2, 3 for vec3, 4 for vec4).

---

source?

optional source?: string

Defined in: packages/sigma/src/rendering/nodes/types.ts:89

Name of the node attribute to read from in NodeDisplayData. If not specified, defaults to the shader attribute name without ‘a_’ prefix. For example, if source is “borderColor”, the value is read from data.borderColor.
