Variable SdfTextRendererConst

Type Declaration

• clearCache: () => void

• font: FontHandler

• init: (stage: Stage) => void

• renderQuads: (
      renderer: CoreRenderer,
      layout: TextLayout,
      _vertexBuffer: null | Float32Array<ArrayBufferLike>,
      renderProps: TextRenderProps,
  ) => void

  Submit SDF glyphs to the renderer's shared batched buffer. Called from CoreTextNode during rendering.

  Three paths:

  1. Exact cache hit — layout, transform, color, and alpha haven't changed. The cached pre-transformed Float32Array is mem-copied directly into the shared SDF buffer (no per-glyph matrix math).
  2. Translation hit — only tx/ty changed (the scroll path). The cached vertices are copied with the position delta applied; the cache keeps its original base so nothing is re-snapshotted.
  3. Cache miss — re-computes per-glyph world-space vertices via addSdfQuads, then snapshots the result into the cache.
