Batching Line Drawing Calls (v16)

Revision 16 of this benchmark created on

Description

Compares drawing a simple shape out of multiple lines compared to one polyline.

This version tests both stroking and filling using polylines.

Preparation HTML

<canvas id="c" width="640" height="480"></canvas>
<script>
  var canvas = document.getElementById('c');
  var context = canvas.getContext('2d');
  context.strokeStyle = 'black';
  context.fillStyle = 'black';
</script>

Setup

context.clearRect(0, 0, canvas.width, canvas.height);
