Provide the model for splitting via a URL pointing to a GLB, STL, or OBJ file of at most 200 MB.

model default character

Splitting method for the model: granularity-based splitting of any model uses 'general', while template-based humanoid splitting uses 'character' and allows optional joints.

part default a

Splitting template when the model is 'character': 'a' produces 6 parts; 'b', 5; 'c', 4 without the head; 'd', 4 with the head; 'e', 3; and 'f', 2.

joint default ball

Type of joint inserted between parts when the model is 'character'.

level default medium

Granularity for splitting when the model is 'general'.

export_format default glb

Output format selection for the generated model, restricted to 'glb' when using character splitting at present.

About Hi3D 3D Part Splitter

Divides a model (GLB, STL or OBJ, up to 200MB) into parts. In character mode, templates a to f give from 6 down to 2 parts, and you can add ball or dovetail joints between them. In general mode, `level` sets low, medium or high granularity. Character splitting currently exports only glb.
