ComfyUI-3D-MeshTool

Introduction: A simple 3D model processing tool within ComfyUI

Partially referenced from everyone's plugins, if there is any inconvenience, please leave a message, and I will promptly remove the corresponding code. For new features or suggestions, please provide feedback.

Note: If the node name has been changed (after update), if there is this old node in the workflow, it will turn red. A new one needs to be created and connected again.

Roadmap:

• Basic Functions
  • ✅ Array sequence (still needs optimization)
  • ✅ Data conversion (may need to add other conversions)
  • ✅ OBJ import (used code from 3dpack, still need to add whether the model is normalized and its data output to retain the original size and position when processing models in batch)
  • ✅ PLY import (The ply point cloud output from industrial software can be imported, and the author tested its feasibility using CloudCompare)
  • 🟩 Simple direct preview window (no need to save first) + preview window for world normals/depth/mask/specified view (can be used for compositing)
  • 🟩 Save, choose which data to save
• Model Optimization
  • ✅ Remove debris
  • ✅ Reduce faces by percentage (vertices)
  • ✅ Cut subdivision
  • 🟩 Turbine smoothing
  • 🟩 Convert to quads
  • 🟩... (other optimizations)
• Model Editing
  • ✅ UV decomposition (xatlas)
  • ✅ Automatic vertex normals
  • 🟩 Group support for ply
  • 🟩 UV remap
  • 🟩 Restore normalized vertices to their original state
  • 🟩 High-poly to low-poly texture/bump baking, AO baking (attempt to convert Blender's code to Comfyui)
  • 🟩 ply segmentation
  • 🟩... (other edits)
• other
  • 🟩 Display any data.
  • 🟩 Example workflow
