Flowmap Canvas | 流向图画布
Flowmap Canvas
Flowmap Canvas is a powerful and easy-to-use tool for creating and editing flowmaps, designed for game developers, 3D artists, and technical artists.
Why Choose Flowmap Canvas?
Compared to other flowmap editing tools on the market, Flowmap Canvas offers these advantages:
- Open Source & Extensible: Built with Python, making it highly customizable and extensible
- Seamless Texture Support: Create perfectly tileable flowmaps with built-in seamless texture editing
- High-Precision Export: Export flowmaps in high-resolution TGA format for professional use
- Non-Destructive Editing: Unlike FlowmapPainter, our brush system adds to existing flowmaps instead of overwriting them, making it perfect for creating complex flow patterns like river branches
- Real-time Preview: Adjust flow speed and distortion in real-time to achieve the perfect effect
- User-friendly interface: Designed for artists, no programming knowledge required
- Performance optimization: Maintains smooth operation even with high-resolution textures
Flowmap Canvas makes creating flowmaps simple and efficient for both beginners and professional artists.
What is a Flowmap?
A flowmap is a special texture used in game development to control the directional flow of materials, commonly used in:
- Controlling water, lava, and other liquid material directions
- Guiding fabric and hair material directions
- Simulating wind effects
- UV distortion and dynamic texture deformation
Flowmaps typically encode direction vectors in the red and green channels:
- Red channel (R) represents flow in the X direction
- Green channel (G) represents flow in the Y direction

Setting Up Python Environment
If you want to run from source code rather than using the packaged executable, follow these steps:
Required Environment Setup
You must install Python in the env/Python directory structure:
- Create the environment structure:
mkdir -p env/Python - Install Python 3.9+ into this directory
- Ensure Python executable is at
env/Python/python.exe
Running the Application
- Run
start.batto start the program using the pre-configured environment - Or manually run:
env\Python\python.exe main.py
How to Use
- Run
start.batto start the program - Use left-click to draw flow, right-click to erase
- Use middle-click to drag canvas, scroll wheel to zoom
- Adjust brush properties through the settings panel
- Export as TGA format for use
System Requirements
- Windows 7/8/10/11
- OpenGL 3.2+ support
- Python 3.9+ (if running from source)
- 4GB RAM recommended
- GPU with OpenGL 3.2 support

流向图画布
流向图画布是一个功能强大、易于使用的流向图(Flowmap)创建和编辑工具，专为游戏开发者、3D艺术家和技术美术工作者设计。
为什么选择流向图画布？
相比市面上其他流向图编辑工具，流向图画布具有以下优势：
- 开源可扩展：使用Python开发，高度可定制和扩展
- 四方连续支持：内置四方连续贴图编辑功能，轻松创建无缝贴图
- 高精度导出：支持导出高分辨率TGA格式，满足专业需求
- 非破坏性编辑：与FlowmapPainter不同，我们的笔刷系统采用叠加模式而不是覆盖模式，特别适合创建复杂的流向图案，如河流支流
- 实时预览：支持实时调整流动速度和扭曲程度，直观预览效果
- 用户友好界面：专为艺术家设计，无需编程知识
- 性能优化：即使处理高分辨率纹理也能保持流畅
流向图画布让流向图的创建变得简单而高效，无论是初学者还是专业艺术家，都能轻松掌握并创建出精美的流向效果。
什么是流向图(Flowmap)？
流向图是游戏开发中使用的一种特殊纹理贴图，用于控制材质的流动方向，常用于以下场景：
- 水流、岩浆等液体材质的方向控制
- 布料、毛发等材质的方向引导
- 风场效果模拟
- UV扰动和动态纹理变形
流向图通常将方向向量编码在红绿通道中：
- 红色通道(R)代表X方向的流动
- 绿色通道(G)代表Y方向的流动

Python环境配置方法
如果您想从源代码运行而不是使用打包好的可执行文件，请按照以下步骤操作：
必要的环境设置
您必须将Python安装到env/Python目录结构中：

mkdir -p env/Python - 在此目录中安装Python 3.9+
- 确保Python可执行文件位于
env/Python/python.exe
运行应用程序
- 运行
start.bat以使用预配置环境启动程序 - 或手动运行：
env\Python\python.exe main.py
使用方法
- 运行
start.bat启动程序 - 使用左键绘制流向，右键擦除
- 使用中键拖动画布，滚轮缩放
- 通过设置面板调整各种参数
- 导出为TGA格式使用
系统要求
- Windows 7/8/10/11
