FR-AI / ANALYSISWhy it is worth attention
It offers a rare example of integrating complex Shadertoy effects into Cesium's 3D globe, and the README openly discusses the ethical challenges of sharing open-source code for learning versus unauthorized reselling.
Who it is for
- Cesium developers seeking to learn custom rendering
- 3D web graphics enthusiasts
- GIS professionals exploring fluid simulations on maps
- Shader porting learners
Use cases
- Learning Cesium Primitive and DrawCommand APIs
- Prototyping real-time fluid or smoke effects on a 3D map
- Understanding Shadertoy-to-Cesium shader porting techniques
Strengths
- Direct integration with Cesium's globe without external dependencies
- Real-time fluid simulation performance demonstrated via ported shaders
- Provides a concrete, commented reference for custom DrawCommand setup
Considerations
- Code is not production-ready and explicitly discouraged for commercial use
- No clear open-source license on ported shader code from other sources
- Author emphasizes the code cannot support any real business logic

其他说明
代码分享本身就是学习技术思路，没有人会把自己赚钱的业务代码分享出来。但是有的人，拿着你分享去开源代码去闲鱼售卖，被发现之后狗急跳墙来一句“就你这开源效果，就TM卖也卖不出去啊”。然后来一句“这不是你代码啊哥们，这只是之前没图随便找了一张图”，然后开启嘲讽、辱骂。“就你这开源效果”到“这不是你代码”，这种前后矛盾的话以及被拆穿后狗急跳墙。
闲鱼售卖 http://bilibili.com/video/BV1sJHSefEhq/ 的人很多，大多数联系上就下架了，这种没素质的，某自称“高德员工”的人是独一份。当然这份代码也同样不支持售卖，几个原因：1.这个代码几乎承载不了任何的业务，它可用作了解Cesium Primitive的绘制机制，了解如何自定义DrawCommand以及如何移植Shadertoy中的多Buffer着色器。2.代码中大多数关键代码来自其他分享渠道，没有明确的开源声明，售卖代码是商业行为。
