![]() ![]() Triangle), then exports it as a glTF file named triangle.gltf (alongside with anĮxternal file resource named vertices.bin): import struct import operator from gltflib import ( GLTF, GLTFModel, Asset, Scene, Node, Mesh, Primitive, Attributes, Buffer, BufferView, Accessor, AccessorType, BufferTarget, ComponentType, GLBResource, FileResource ) vertices = vertex_bytearray = bytearray () for vertex in vertices : for value in vertex : vertex_bytearray. The example below creates a simple glTF 2.0 mode in memory (consisting of a single ![]() To export a model, call the GLTF.export() instance method in the GLTF class. The binary dataĬan be accessed using the data property: resource = glb. resources ) # įor embedded resources, the content is parsed into memory automatically. load ( 'glTF-Sample-Models/2.0/BoxTextured/glTF-Binary/BoxTextured.glb' ) print ( glb. They will be of type GLBResource instead of FileResource: glb = GLTF. In either case, now the file resource data can be accessed via the data property: print ( resource. load ( filename, load_file_resources = True ) load () # Assumes resource is a FileResourceĪnother way is to pass the load_file_resources flag when calling GLTF.load(): gltf = GLTF. Is to call the load() method on the resource: resource = gltf. You can load the resource into memory in one of two ways. ![]() Note that the actual content of these external file resources is not loaded by default Property after loading a model: print ( gltf. In either case, the resources are parsed alongside the model structure into the resources Resources can be embedded as part of the model file, or (as with the above example) be uri ) # BoxTextured0.binĪ glTF 2.0 model may contain resources, such as vertex geometry or image textures. You can also inspect the various model properties: print ( gltf. model ) # GLTFModel(extensions=None, extras=None, accessors=[Accessor(extensions=None, extras=None, name=None, bufferView=0, byteOffset=0, componentType=5123. Alternatively, you can use GLTF.load_gltf(filename) or GLTF.load_glb(filename).Īfter loading, you can inspect the model structure by accessing the model property: print ( gltf. The type of the file will be determined based on the filenameĮxtension. The GLTF.load static method supports loading both the JSON-based. load ( 'glTF-Sample-Models/2.0/BoxTextured/glTF/BoxTextured.gltf' ) To load a glTF 2.0 model: from gltflib import GLTF gltf = GLTF. TheĮxample models come from the Khronos glTF-Sample-Models repository available here: ![]() The examples below illustrate how to use this library for a couple sample scenarios. This library can be installed using pip: pip install gltflib Inside a glTF/GLB file between external files or web URLs, data URLs, and embedded GLB This data into a properly formatted glTF/GLB file. Responsible for managing the actual geometry data yourself. This library is intended for working with glTF 2.0 at a fairly low level, meaning you are Library for parsing, creating, and converting glTF 2.0 files in Python 3.6+. ![]()
