让机器人研究者零基础快速用Blender做专业动画和可视化。
APOLLO Blender: A Robotics Library for Visualization and Animation in Blender
- 提供URDF等标准格式的机器人与环境导入功能。
- 通过Python脚本轻松实现机器人状态关键帧控制。
- 一键生成3D示意图，适合论文配图与演示视频制作。
高质量可视化是机器人研究的重要组成部分，有助于通过图表、动画和演示视频清晰传达研究成果。尽管Blender是一款强大且免费的3D图形平台，但其陡峭的学习曲线和缺乏机器人专用集成，使研究人员难以高效使用。本文提出一个轻量级软件库APOLLO Blender，通过简单的脚本接口解决常见机器人可视化任务。该库支持：(1) 直接从标准描述格式（如URDF）导入机器人与环境；(2) 基于Python的脚本工具实现机器人状态与视觉属性的关键帧控制；(3) 快速生成用于示意性图表与动画的3D基本几何体。这些功能使研究人员无需具备深厚的Blender技能，即可快速生成可发表的图像、动画和解释性示意图。我们通过一系列概念验证示例展示其应用，并讨论当前局限与未来扩展方向。
原文摘要 · Abstract (English)
High-quality visualizations are an essential part of robotics research, enabling clear communication of results through figures, animations, and demonstration videos. While Blender is a powerful and freely available 3D graphics platform, its steep learning curve and lack of robotics-focused integrations make it difficult and time-consuming for researchers to use effectively. In this work, we introduce a lightweight software library that bridges this gap by providing simple scripting interfaces for common robotics visualization tasks. The library offers three primary capabilities: (1) importing robots and environments directly from standardized descriptions such as URDF; (2) Python-based scripting tools for keyframing robot states and visual attributes; and (3) convenient generation of primitive 3D shapes for schematic figures and animations. Together, these features allow robotics researchers to rapidly create publication-ready images, animations, and explanatory schematics without needing extensive Blender expertise. We demonstrate the library through a series of proof-of-concept examples and conclude with a discussion of current limitations and opportunities for future extensions.
