摘要

本文提出了一种低成本的二维图形抗混叠渲染方案。该方案首先采用本地最小表(local minimum table, LMT)方法存储边缘信息。接下来,扫描线缓冲区与LMT一起使用,以生成已排序的活动边表。基于所提出的扫描线缓冲区编码方案,可以将扫描线缓冲区的大小减少78%。最后,将FLIPQUAD多采样模式应用于我们的渲染系统,可以节省25%的片上缓冲区大小,并降低25%的处理复杂性。

A low cost 2D graphics anti-aliasing rendering scheme
In this paper, a low cost anti-aliasing rendering scheme for 2D graphics is proposed. This scheme first adopts the local minimum table (LMT) approach to store the edge information. Next, a scan-line buffer is used with LMT to generate the sorted active edge table. Based on the proposed coding scheme for scan-line buffer, the size of buffer can be reduced by 78%. Finally, a FLIPQUAD multisampling pattern has been applied to our rendering system, which can lead to 25% saving of the on-chip buffer size, and 25% reduction of processing compexity.
