Pixal3D

Pixal3D is an advanced AI-powered platform designed for generating high-fidelity 3D models and character animations. It offers a comprehensive suite of tools for artists, developers, and designers to transform 2D images into pixel-aligned 3D GLB models and create FBX motion files from text prompts. The platform integrates cutting-edge AI models like Pixal3D, Trellis 2, and Hunyuan Motion, providing versatile options for various 3D generation needs.

Key Features and Capabilities:

• Image-to-3D Generation (Pixal3D & Trellis 2):

  • Pixal3D Back-Projection: Generate faithful, pixel-aligned GLB 3D models directly from single 2D images. This process ensures high fidelity and accurate representation of the source image in 3D space, complete with PBR textures.
  • Trellis 2 Integration: Offers an alternative image-to-3D generation pipeline, allowing users to compare different reconstruction styles and leverage a fallback option for diverse results. This is particularly useful for exploring various aesthetic outcomes or addressing specific model requirements.
  • Quality Presets: Users can choose from "Fast" (preview), "Balanced" (default), and "Detail" (high detail) presets to control texture resolution and target vertex count, optimizing for speed or final fidelity.
  • Input Guidelines: Provides clear recommendations for source images, including full subject in frame, clear silhouette and edges, low occlusion, simple background, high-resolution, and neutral lighting, to ensure optimal 3D generation results.

• Text-to-Motion Generation (Hunyuan Motion):

  • FBX Motion Output: Generate dynamic character animations from simple text descriptions. This feature is ideal for quickly prototyping character movements or adding life to 3D models without manual animation.
  • Motion JSON: Alongside FBX, users can download motion JSON outputs for further customization or integration into other animation workflows.

• User-Centric Workspace:

  • Account-Based System: All generation tasks require a user account and consume credits, ensuring a structured and managed workflow.
  • Task History & Stored Outputs: Generated models and motion files are stored within the user's account, allowing for easy access, review, and download of GLB, FBX, and JSON outputs. Provider files are normalized and rehosted through project storage.
  • Cloudflare Worker Deployment: The application is optimized for performance and scalability, configured for OpenNext on Cloudflare Workers.

• Comprehensive Free 3D Tools:

  • Pixal3D extends its utility with a suite of free, browser-based tools that run locally, ensuring privacy and no credit consumption. These tools are invaluable for preparing source assets and inspecting generated outputs:
    • 3D Model Viewer: Inspect GLB, OBJ, STL, and FBX models.
    • GLB Inspector: Analyze GLB structure, scenes, meshes, materials, and animations.
    • 3D Format Converter: Convert between GLB, OBJ, and STL formats.
    • Texture Checker: Verify texture dimensions and GPU memory.
    • Model Scale Calculator: Calculate real-world model scale.
    • Image Compressor & Converter: Optimize and convert source images (PNG, JPG, WebP).
    • Transparent PNG Maker: Create transparent backgrounds for source assets.

• Official Resources & Community:

  • Provides direct links to the official Pixal3D arXiv paper, GitHub repository, Hugging Face model, and project page, offering transparency and access to the underlying research and development.
  • Features a 3D Sample Gallery showcasing official results from the research paper, complete with input images and links to generated GLB meshes.
