Creates a B3DM body from numpy arrays.

Parameters:

  • points – array of vertex positions, must have a (n, 3) shape.

  • triangles – array of triangle indices, must have a (n, 3) shape.

  • batch_table – a batch table.

  • feature_table – a feature table.

  • normals – array of vertex normals, must have a (n, 3) shape.

  • uvs – array of texture coordinates, must have a (n, 2) shape.

  • batchids – array of batch table IDs, must have a (n) shape.

  • texture_uri – the URI of the texture image if the primitive is textured.

  • material – a glTF material. If not set, a default material is created.

sync() → None[source]

Allow to synchronize headers with contents.
