LineX - Visual Manim Editor

LineX is a powerful, visual-first IDE for creating Manim animations. It bridges the gap between code-based animation and modern video editing, allowing users to create mathematical animations using a drag-and-drop interface, real-time preview, and AI automation.

🚀 Key Features

🎨 Visual Canvas

• Drag & Drop: Add shapes (Circles, Squares, Triangles) and Math symbols ($\pi$, $\sum$, $\int$) directly from the toolkit.
• Direct Manipulation: Select objects to Move, Scale, and Rotate visually.
• Mini-Tool: A context-aware floating toolbar appears near your selection for quick style edits (Color, Stroke Width).

🤖 Gemini AI Automation

• Natural Language to Animation: Type prompts like "Create a rotating red square with text" and watch LineX generate the code and render the video automatically.
• Smart Chat: Authentically styled AI Assistant that helps you write Manim code.
• Robust Pipeline: Automatically cleans and validates AI-generated code to prevent render errors.

🎬 Professional Timeline

• Non-Linear Editing: A Premiere Pro-style timeline with V1 (Video) and A1 (Audio) tracks.
• Clip Management: Drag generated clips to arrange them in time.
• Transitions: Add visual transitions between your animation clips.

⚡ Real-Time Rendering

• Instant Preview: Renders scenes in the background and plays them immediately on the canvas.
• Quality Control: Switch between Low (480p) for fast previews and High (1080p) for final export.

🛠️ Installation

Prerequisites

1. Python 3.10+
2. FFmpeg (Required for Manim and video playback)
   • Windows: choco install ffmpeg or download from ffmpeg.org and add to PATH.

Setup

1. Clone the Repository

   git clone https://github.com/yourusername/LineX.git
   cd LineX

2. Install Dependencies

   pip install -r requirements.txt

   Note: If you don't have a requirements file yet, install the core packages:

   pip install manim PySide6 google-generativeai python-dotenv

3. Configure API Keys

   • Create a .env file in the root directory.
   • Add your Google Gemini API Key:

     GEMINI_API_KEY=your_api_key_here

▶️ Usage

1. Run the Application

   python -m src.main

2. Workflow

   • Option A (Visual): Drag shapes from the left Toolkit onto the canvas. Use the Properties Panel on the right to adjust them.
   • Option B (AI): Open the AI Assistant panel, type a request, and hit Enter. LineX will generate the code and show you the result.
