Experiment 2.2 Model rendering edges are jagged

The rendered calf has strange jagged edges

After trying to change the shading part to depth values, the jagged edges are still present

So it feels that the issue might be with the z‑buffer test? But it’s unclear which function the problem lies in.
I saw on Jiaoda Gate that last year a classmate had a very similar problem, but it seems it wasn’t resolved, so I’d like to ask where the problem is.

The problem has been resolved, most likely in the vertex_shader and inside_triangle functions, where incorrect coordinate transformation passing and incorrect inside‑triangle determination caused jagged edges on the model’s border faces.
