Emotion Ball Community License
Emotion Ball 社区许可（非商业免费；引擎与表情数据可另行商业授权；球形角色视觉形象永不商用）
Copyright (c) 2026 sam70361 (仅就独立编写的源代码、表情配置数据与文档部分)
适用范围 / Scope: 本许可仅适用于仓库根目录及 emotion-ball/ 目录的内容
（球形角色项目及其站点与文档）。mood-mates/ 子目录为独立原创角色子项目，
受其自带的 mood-mates/LICENSE（社区许可）与 mood-mates/LICENSE-COMMERCIAL.md
（商业许可）约束，不适用本许可。
This license applies only to the contents at the repository root and in the
emotion-ball/ directory (the ball-character project, its site and docs). The
mood-mates/ subdirectory is an independent original-character sub-project
governed by its own mood-mates/LICENSE (community) and
mood-mates/LICENSE-COMMERCIAL.md (commercial); this license does not apply
to it.
【中文】
0. 内容划分：本项目包含两类授权不同的内容——
(A) 表情引擎与表情数据：源代码（状态机、弹簧插值动画、球面投影、
渲染与配置注册中心等）、表情配置数据（眼环 / 眼形 / 嘴形参数、
动画原语与关键帧序列）以及配套文档，均为独立编写与设计；
(B) 球形角色视觉形象：blob / wedge / gem 身体造型、配色方案、彩带等
特效视觉，及其组合形成的整体角色形象。
1. 非商业使用（适用于 A 与 B）：允许免费查看、下载、运行、修改本项目，
并在注明出处的前提下，在个人学习、研究与技术交流等非商业场景中分享
本项目或其衍生作品。
2. 商业使用（仅限 A）：表情引擎与表情数据可通过商业授权用于商业用途，
通用条款见仓库根目录 LICENSE-COMMERCIAL.md；商业授权请联系
1251579308@qq.com。
3. 视觉形象永不商用（B）：球形角色视觉形象仅供个人技术学习与研究，
禁止任何商业用途；该部分不提供、也永不提供商业授权。取得商业授权的
被许可方亦不得将球形角色视觉形象用于商业用途，须搭配自有或另行合法
授权的角色形象使用。详见仓库根目录 NOTICE.md。
4. 未经商业授权，禁止将本项目或其衍生作品用于任何商业用途，包括但不
限于售卖、付费授权、集成到商业产品或服务、用于商业推广等。
5. 分发本项目或其衍生作品时，须完整保留本许可声明、版权信息与

6. 本项目按"现状"提供，不附带任何明示或默示的担保；因使用本项目产生
的任何风险与责任由使用者自行承担。
[English]
0. CONTENT CLASSES: this project contains two differently licensed classes
of content —
(A) Expression engine & emotion data: the source code (state machine,
spring interpolation, spherical projection, rendering, config
registry, etc.), the emotion configuration data (eye-ring / eye-shape
/ mouth-shape parameters, animation primitives and keyframe
sequences) and the accompanying documentation, all independently
written and designed;
(B) Ball-character visual designs: the blob / wedge / gem body
silhouettes, color schemes, ribbon and other FX visuals, and the
overall character appearance they form together.
1. NON-COMMERCIAL USE (applies to both A and B): viewing, downloading,
running and modifying this project free of charge, and sharing this
project or derivative works with proper attribution in non-commercial
scenarios (personal learning, research and technical exchange) are
permitted.
2. COMMERCIAL USE (A only): the expression engine and emotion data may be
used commercially under a commercial license; see LICENSE-COMMERCIAL.md
in the repository root for the general terms, and contact
1251579308@qq.com for licensing.
3. VISUAL DESIGNS NEVER COMMERCIAL (B): the ball-character visual designs
are provided solely for personal technical study and research; any
commercial use is prohibited, and no commercial license is or will ever
be offered for them. Even commercial licensees must not use the
ball-character visual designs commercially and must pair the licensed
materials with their own or otherwise lawfully licensed character
designs. See NOTICE.md in the repository root.
4. Without a commercial license, any commercial use of this project or its
derivative works is prohibited, including but not limited to selling,
paid licensing, integration into commercial products or services, or use
in commercial promotion.
5. This license notice, the copyright notice and NOTICE.md must be retained
in all copies or substantial portions of the project.
6. The project is provided "AS IS", without warranty of any kind, express or
implied. All risks and liabilities arising from its use are borne by the
user.
