Method _packStructArray

src/webgpu/p5.RendererWebGPU.js:3532–3547

(data, schema)

    // Packs an array of plain objects into a Float32Array using the given struct schema.
    // Reuses _packField so layout rules match uniform packing exactly.
    _packStructArray(data, schema) {
      const { fields, stride } = schema;
      const totalBytes = Math.max(data.length * stride, 16);
      const alignedBytes = Math.ceil(totalBytes / 16) * 16;
      const buffer = new ArrayBuffer(alignedBytes);
      const floatView = new Float32Array(buffer);
      const dataView = new DataView(buffer);
      for (let i = 0; i < data.length; i++) {
        const item = data[i];
        const baseOffset = i * stride;
        for (const field of fields) {
          this._packField(field, item[field.name], floatView, dataView, baseOffset);
        }
      }

    // Inverse of _packStructArray reads packed buffer back into plain JS objects
    // using the same schema layout - fields, stride and offsets
