uploadGeometry method

@override GeometryBuffer uploadGeometry(ByteData bytes, GeometryUsage usage)

Uploads geometry that will outlive the frame.

Every mesh in the engine comes through here, plus the two buffers the renderer keeps: the full-screen triangle and the identity index sequence the debug overlay draws through. Per-frame geometry does not — see PassEncoder.bindVertexData.

usage is required and cannot be defaulted; see GeometryUsage for the backend that binds a buffer to its target permanently.

Implementation

@override
GeometryBuffer uploadGeometry(ByteData bytes, GeometryUsage usage) {
  final buffer = inner.uploadGeometry(bytes, usage);
  _baseOffsets[buffer.backend] = buffer.offsetInBytes;
  events.add(
    TraceUploadGeometry(
      id: _name(_geometryIds, buffer.backend),
      usage: usage,
      bytes: _copy(bytes),
    ),
  );
  return buffer;
}
