generateLabelVertexShader

generateLabelVertexShader(): string

Defined in: packages/sigma/src/rendering/nodes/labels/generator.ts:41

Generates the label vertex shader, which positions glyphs from the shared edge distance (read from the frame texture) rather than searching the SDF.

Coordinate Systems

• Graph space: Node positions (a_anchorPosition)
• Clip space: After u_matrix transform, range [-1, 1]
• Screen space: Pixel positions, Y-down

Returns

string
