I previously created a 3D modeling tool called "pelogen".
It was designed to run on pico-8 with a minimum amount of data, and with its 16x16x16 vertex coordinates and one-stroke triangulation, it was almost exclusively a tool for myself.

This time, the specifications were revised from there, and the tool was created with an eye to making the data a bit larger and easier to model.

• The vertices will be edited in such a way that triangles are added, instead of the specification of adding vertices one by one.
  And we will set a color for each face.
  

  

• You can JOIN the vertices of each triangle to simplify vertex movement and build complex shapes.

• You can duplicate selected triangles and rotate or flip vertices by a limited number of angles.
  

  

• Data management of the model becomes more intuitive and easier to understand.
  
  

Development is about 90% complete until ready for release.
Data import/export, sample code, and model size limit checks remain.
