Section titled “defaultValue?”
optionaldefaultValue?:string|number|boolean
Defined in: packages/sigma/src/rendering/nodes/types.ts:96
Default value to use when the source attribute is missing from node data. For size=1: a number or boolean (packed as 1/0) For size=4 with normalized: a CSS color string (e.g., “#ff0000”)
name:
string
Defined in: packages/sigma/src/rendering/nodes/types.ts:67
Name of the attribute in the shader (e.g., “a_borderSize”).
normalized?
Section titled “normalized?”
optionalnormalized?:boolean
Defined in: packages/sigma/src/rendering/nodes/types.ts:82
Whether the attribute should be normalized when passed to the shader.
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?
Section titled “source?”
optionalsource?: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.

number
Defined in: packages/sigma/src/rendering/nodes/types.ts:77
