Abstract: A two dimensional (2D) vector graphics triangulation system and a method thereof are provided. The system includes a memory module and a triangle mesh processing module. The memory module temporarily stores a triangle mesh triangulated from a 2D vector graphics into a binary tree data structure. The triangle mesh processing module adjusts the triangle mesh, or re-performs a triangulation processing to a local region of the loop when a state of a loop of the 2D vector graphics is changed. The triangle mesh processing module includes a level of detail unit, which proportionally adjusts an error threshold according to a zoom condition of the loop, updates an error value of each boundary line when the loop is deformed, and splits a boundary line or merges two neighboring boundary lines according to the error values of the boundary lines and the error threshold.

Abstract: A stretch strap of a chair has multiple stretch ropes and a soft sleeve. The soft sleeve receives the two stretch ropes therein. Each stretch rope has multiple rubber cords and a covering layer binding the rubber cords therein. Since the covering layer is a weave, so there are gaps on the covering layer and a concave is formed between the two adjacent stretch ropes, when the stretch ropes are tied together. However, the woven covering layer is inside of the soft sleeve, the soft sleeve prevents dirt from receiving in the gaps and the concaves. In addition, a chair user directly sits on the soft sleeve not on the woven covering layers and feels comfortable.
