## Description

DanmakuFlameMaster is a high-performance rendering engine for displaying scrolling bullet comments on Android devices. It functions as a graphic engine that manages the lifecycle of on-screen comments, from parsing raw data to final visual display.

The project is distinguished by its use of hardware-accelerated surface views and multi-core parallel processing to maintain smooth frame rates during high-volume content delivery. It employs a pre-caching layout engine to calculate text dimensions and motion paths before they are displayed on the screen.

The system includes a rule-based visibility filter for real-time content moderation and a dedicated parser for converting XML formatted comment data into memory-efficient objects.
