Flowmap Canvas

Flowmap Canvas is a powerful and easy-to-use flowmap drawing tool, designed for game developers and 3D 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
• 3D Model Drawing Support: Draw flow effects directly on 3D models
• Better Drawing Experience: Unlike other drawing tools, our brush system uses additive mode instead of overwrite mode, making it easy to draw flow branches and improving the drawing experience
• Real-time Preview: Adjust flow speed and distortion in real-time for intuitive preview
• High-Precision Export: Export flowmaps in high-resolution TGA format for professional use

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

• 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

Features

Easy-to-Use Drawing System

• Drawing strokes don't overwrite previous drawing results
• Real-time flow effect preview for intuitive understanding of results

Powerful Editing Features

• Seamless texture editing support
• Support for drawing on 3D models and collaborative drawing between 2D and 3D interfaces

Advanced Preview Features

• Tile preview mode support
• Real-time flow animation preview
• Adjustable flow speed and distortion

Complete File Operations

• Load and save flowmaps
• Export to high-resolution TGA format

Download Application

If you want to use this tool directly, please download the latest software from the Release page. Currently only x86 windows version is released. https://github.com/dolag233/FlowmapCanvas/releases

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)绘制工具，专为游戏开发者、3D艺术家设计。

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
• 支持模型绘制: 支持在三维模型上直接绘制流动效果
• 更优的绘制体验：与其他绘制工具不同，我们的笔刷系统采用叠加模式而不是覆盖模式，能够轻松绘制流向分支，提升绘制体验
• 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
• 高精度导出：支持导出高精度TGA格式，满足专业需求

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
• 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

功能特性

好用的绘制系统

• 绘制笔触不会覆盖之前的绘制结果
• 实时预览流动效果，直观了解绘制结果

强大的编辑功能

• 支持四方连续(Seamless)贴图编辑
• 支持在3D模型上绘制以及2D和3D界面协同绘制

高级预览功能

• 支持预览重复(Tile)模式
• 实时流动动画预览
• 可调整流动速度和扭曲程度

完善的文件操作

• 支持加载和保存流向图
• 支持导出为高精度TGA格式
