ThorVG的CPU-only演示，这是一个高性能的2D矢量图形引擎。
我制作了一个演示应用程序，以展示ThorVG引擎的性能。
主要特点：
- 每个敌人由86个粒子组成，屏幕上最多可显示约300个敌人。
- 全尺寸（2K）细腻的光晕背景位图图像和4层100颗星星的层次。
- 实时阴影和模糊效果，适用于飞船、导弹、图形用户界面和轮廓。
- 在峰值负载时，约25,000个绘图对象同时渲染。
- 在2K分辨率下，使用软件渲染器运行稳定，帧率超过120 FPS（在Apple M2 Pro上测试）。

代码库：[https://github.com/thorvg/thorvg.janitor](https://github.com/thorvg/thorvg.janitor)
该演示特别强调了软件渲染器（仅限CPU）。支持GPU后端（OpenGL/WebGPU），但优化工作仍在进行中。
ThorVG是一个开源高性能2D矢量图形引擎，旨在用于嵌入式、移动和网络系统。此演示旨在作为性能展示和压力测试。欢迎反馈和贡献！

I’ve built a demo app to showcase the performance of the ThorVG engine.
Key features:<p>- Each enemy consists of 86 particles, with up to ~300 enemies on screen.<p>- Full-size (2K) subtle halo glow background bitmap image and 4 × 100 star layers.<p>- Real-time DropShadow and BlurEffects for ships, missiles, GUI, and outlines.<p>- At peak load, ~25,000 drawing objects rendered together.<p>- Runs fully stable at 120+ FPS with the Software Renderer on 2K resolution (tested on Apple M2 Pro).<p>Demo video: https://www.youtube.com/watch?v=jdnnzmtHy9k<p>Repo: https://github.com/thorvg/thorvg.janitor<p>This demo specifically highlights the Software Renderer (CPU only). GPU backends (OpenGL/WebGPU) are supported, but optimization work is ongoing.<p>ThorVG is an open-source high-performance 2D vector graphics engine designed for embedded, mobile, and web systems. This demo is intended as a performance showcase and stress test. Feedback and contributions are welcome!
