GLTFMesh

class compas.files.GLTFMesh(primitive_data_list, context, mesh_name=None, weights=None, extras=None, extensions=None)[source]

Bases: object

Object containing mesh data in a format compatible with the glTF standard.

Attributes

• mesh_name (str) – String of the name of the mesh.

• weights (list) – List containing the weights to be applied to morph targets.

• primitive_data_list (list) – List of objects defining the geometry and material of the mesh.

• extras (object)

• extensions (object)

• context (GLTFContent) – GLTF context in which the mesh exists.

• key (int) – Key of the mesh used in compas.files.GLTFMesh.context.meshes.

• vertices (list) – List of xyz-tuples representing the points of the mesh.

• faces (list) – List of tuples referencing the indices of compas.files.GLTFMesh.vertices representing faces of the mesh.

Methods

from_data	Creates a compas.files.GLTFMesh from a glTF node dictionary and inserts it in the provided context.
from_mesh	Construct a compas.files.GLTFMesh object from a compas mesh.
from_vertices_and_faces	Construct a compas.files.GLTFMesh object from lists of vertices and faces.
group_indices	Returns a list of the elements of indices grouped into tuples of size group_size.
shift_indices	Given a list of indices, returns a list of indices, all shifted by shift.
to_data	Returns a JSONable dictionary object in accordance with glTF specifications.
validate_faces	Raises an exception if not all faces in faces are defining either all triangles, lines or points.
validate_vertices	Raise an exception if there are either too many vertices, or the vertices do not represent points in 3-space.
