Background of the matter: I am working on the gltf model, which does not store normals, causing the model to look bad. Therefore, I want to calculate normals myself based on the known content (points, indices)
I used the data (points, indices) in the following figure to calculate the triangle normals through cross multiplication, but I am unable to restore the data (normals)
