Segments is a lightweight line renderer for DOTS tech stack.

It works by creating mesh batches formatted as MeshTopology.Lines, SystemBase job system schedules updates with MeshDataArray. Geometry shader creates output triangles on the GPU.

Segments.Batch _batch;
void OnEnable () => Segments.Core.CreateBatch( out _batch );
void OnDisable () => _batch.Dispose();
void Update ()
{
	_batch.Dependency.Complete();

	var buffer = _batch.buffer;
	buffer.Length = 3;
	Vector3 position = transform.position;
	buffer[0] = new float3x2( position , position+transform.right );
	buffer[1] = new float3x2( position , position+transform.up );
	buffer[2] = new float3x2( position , position+transform.forward );
}

100_000 segments? No problem!

@todo: details

• Unity 2020.1
• Hybrid Renderer (tested with URP, HDRP will require few more lines here and there to be fully compatible)

• mesh wireframe (runtime)

• drawing mesh bounding boxes (runtime)
