Detailed Description

Read a GLTF file.

vtkGLTFReader is a concrete subclass of vtkMultiBlockDataSetAlgorithm that reads glTF 2.0 files.

The GL Transmission Format (glTF) is an API-neutral runtime asset delivery format. A glTF asset is represented by:

A JSON-formatted file (.gltf) containing a full scene description: node hierarchy, materials, cameras, as well as descriptor information for meshes, animations, and other constructs
Binary files (.bin) containing geometry and animation data, and other buffer-based data
Image files (.jpg, .png) for textures

This reader currently outputs a vtkMultiBlockDataSet containing geometry information for the current selected scene, with animations, skins and morph targets applied, unless configured not to (see ApplyDeformationsToGeometry).

It is possible to get information about available scenes and animations by using the corresponding accessors. To use animations, first call SetFramerate with a non-zero value, then use EnableAnimation or DisableAnimation to configure which animations you would like to apply to the geometry. Finally, use UPDATE_TIME_STEPS to choose which frame to apply. If ApplyDeformationsToGeometry is set to true, the reader will apply the deformations, otherwise, animation transformation information will be saved to the dataset's FieldData.

Materials are currently not supported in this reader. If you would like to display materials, please try using vtkGLTFImporter. You could also use vtkGLTFReader::GetGLTFTexture, to access the image data that was loaded from the glTF 2.0 document.

This reader only supports assets that use the 2.x version of the glTF specification.

For the full glTF specification, see: https://github.com/KhronosGroup/glTF/tree/master/specification/2.0

Note: array sizes should not exceed INT_MAX

◆ GetNumberOfAnimations()

virtual vtkIdType vtkGLTFReader::GetNumberOfAnimations ( )

virtual

glTF models can contain multiple animations, with various names and duration.

glTF does not specify however any runtime behavior (order of playing, auto-start, loops, mapping of timelines, etc), which is why no animation is enabled by default. These accessors expose metadata information about a model's available animations.

◆ GetAnimationName()

std::string vtkGLTFReader::GetAnimationName ( vtkIdType animationIndex )

glTF models can contain multiple animations, with various names and duration.

glTF does not specify however any runtime behavior (order of playing, auto-start, loops, mapping of timelines, etc), which is why no animation is enabled by default. These accessors expose metadata information about a model's available animations.

◆ GetAnimationDuration()

float vtkGLTFReader::GetAnimationDuration ( vtkIdType animationIndex )
