🔨 To Do

  • Create an example test.gds file.
  • Animate it in Blender with the layers seperating and rotating.
  • Upload a .gif to the README.md as the header image.

Conversion of .gds to .gltf

  • Create and display a working .gltf file in Blender using GDS2glTF.
  • Get the GDS2glTF code running.
  • Display the .gltf file in blender.
  • Debug the placing of the individual components! Currently, x and y seem to be correct, but not the angle a.
  • Now the angle seems correct. But the placing is all at the origin. Fix this.
  • Scale down the size! Right now it is so large, Blender is only showing items within a certain distance.
  • Fix bug where flipped or flopped objects are not positioned correctly.
  • [-] Give the layers the correct height and depth in the z-direction. This can be done by modifying the layers.py.
  • Add optional argument to merge cells within layers to avoid crossing rendering artifacts!

Add Blender Template Scenes

  • finger.blend contains a scene with a substrate on top a finger. Import your file and place it there. Simple lighting and animation has been preset so you can simply go ahead and render a short animation already.
  • coin.blend provides a simple scene with a white/grey background under studio lighting and a coin for reference.
  • packaging.blend provides a demo scene with a chip being packaged including bonding.

Lifeview of .gltf in Browser

The Basic Software Workflow

  1. Install GDS2glTF. (Also compare to https://github.com/mbalestrini/gdsiistl.)
  2. Install tinytapeout_gds_viewer.
  3. Convert your .gds file to a .gds.gltf file using GDS2gITF.
  4. View the .gds.gltf file in the browser using the gds viewer.

Ideas

  • Write a Python wrapper to convert and display any .gds in the browser with just a simple function and create a unified repository that is easy to use & understand.
  • Add grid view (showing only the edges/lines) for a more tron feel.
  • Export to Blender (.stl can be imported in Blender!) (See this tutorial)
    • Add materials and ray tracing (maybe just do this in blender).
  • Export the view in high res .png with or without background from the live view.
  • Give the layers materials directly in the layers.py. Use reference images.
  • Add a substrate layer.
  • Add boolean operations to mimic growth and edging.
  • Integrate a 3D renderer using C++ or Python to show and render the file without any third-party software.

GDS3D

https://github.com/trilomix/GDS3D is a different 3D .gds viewer using C++ that seems quite advanced yet hasn't been updated in 4 years.

GDS2glTF

This first version was built to create .glTF 3D files from SDK130 PDK .gds files. Alot of the work is based on the gdsiistl repo: https://github.com/dteal/gdsiistl which then continued in https://github.com/mbalestrini/GDS2glTF.

.glTF (GL Transmission Format) is used for 3D models in both web and native applications like Blender, Unity3D, Unreal Engine 4, or Godot. See Blender's docs for more information.
