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:

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

virtual void vtkGLTFReader::SetFileName ( const char *  )
virtual

Set/Get the name of the file from which to read points.

◆ GetFileName()

virtual char* vtkGLTFReader::GetFileName ( )
virtual

◆ SetApplyDeformationsToGeometry()

void vtkGLTFReader::SetApplyDeformationsToGeometry ( bool  flag)

The model's skinning transforms are computed and added to the different vtkPolyData objects' field data.

If this flag is set to true, the reader will apply those skinning transforms to the model's geometry.

◆ GetApplyDeformationsToGeometry()

virtual bool vtkGLTFReader::GetApplyDeformationsToGeometry ( )
virtual

◆ ApplyDeformationsToGeometryOn()

virtual void vtkGLTFReader::ApplyDeformationsToGeometryOn ( )
virtual

◆ ApplyDeformationsToGeometryOff()

virtual void vtkGLTFReader::ApplyDeformationsToGeometryOff ( )
virtual

◆ 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)

◆ GetAnimationDuration()

float vtkGLTFReader::GetAnimationDuration ( vtkIdType  animationIndex)

◆ EnableAnimation()

void vtkGLTFReader::EnableAnimation ( vtkIdType  animationIndex)

Enable/Disable an animation.

The reader will apply all enabled animations to the model's transformations, at the specified time step. Use UPDATE_TIME_STEP to select which frame should be applied.

◆ DisableAnimation()

void vtkGLTFReader::DisableAnimation ( vtkIdType  animationIndex)

◆ IsAnimationEnabled()

bool vtkGLTFReader::IsAnimationEnabled ( vtkIdType  animationIndex)

◆ GetSceneName()

std::string vtkGLTFReader::GetSceneName ( vtkIdType  sceneIndex)

glTF models can contain multiple scene descriptions.

These accessors expose metadata information about a model's available scenes.

◆ GetNumberOfScenes()

virtual vtkIdType vtkGLTFReader::GetNumberOfScenes ( )
virtual

◆ GetCurrentScene()

virtual vtkIdType vtkGLTFReader::GetCurrentScene ( )
virtual

Get/Set the scene to be used by the reader.

◆ SetCurrentScene()

virtual void vtkGLTFReader::SetCurrentScene ( vtkIdType  )
virtual

◆ SetScene()

void vtkGLTFReader::SetScene ( const std::string &  scene)

◆ GetFrameRate()

virtual unsigned int vtkGLTFReader::GetFrameRate ( )
virtual

Get/Set the rate at which animations will be sampled: the glTF format does not have the concept of static timesteps.

TimeSteps are generated, during the REQUEST_INFORMATION pass, as linearly interpolated time values between 0s and the animations' maximum durations, sampled at the specified frame rate. Use the TIME_STEPS information key to obtain integer indices to each of these steps.

◆ SetFrameRate()

virtual void vtkGLTFReader::SetFrameRate ( unsigned int  )
virtual

◆ GetAllSceneNames()

vtkStringArray* vtkGLTFReader::GetAllSceneNames ( )

Get a list all scenes names as a vtkStringArray, with duplicate names numbered and empty names replaced by a generic name.

All names are guaranteed to be unique, and their index in the array matches the glTF document's scene indices.

◆ GetAnimationSelection()

vtkDataArraySelection* vtkGLTFReader::GetAnimationSelection ( )

Get the vtkDataArraySelection object to enable/disable animations.

◆ StoreTextureData()

void vtkGLTFReader::StoreTextureData ( )
protected

Create and store GLTFTexture struct for each image present in the model.

◆ RequestInformation()

int vtkGLTFReader::RequestInformation ( vtkInformation ,
vtkInformationVector **  ,
vtkInformationVector  
)
overrideprotectedvirtual

This is called by the superclass.

This is the method you should override.

Reimplemented from vtkMultiBlockDataSetAlgorithm.

◆ RequestData()

int vtkGLTFReader::RequestData ( vtkInformation ,
vtkInformationVector **  ,
vtkInformationVector  
)
overrideprotectedvirtual

This is called by the superclass.

This is the method you should override.

Reimplemented from vtkMultiBlockDataSetAlgorithm.

◆ CreateSceneNamesArray()

void vtkGLTFReader::CreateSceneNamesArray ( )
protected

Create the SceneNames array, generate unique identifiers for each scene based on their glTF name, then fill the SceneNames array with the generated identifiers.

◆ CreateAnimationSelection()

void vtkGLTFReader::CreateAnimationSelection ( )
protected

Fill the AnimationSelection vtkDataArraySelection with animation names.

Names are adapted from the glTF document to ensure that they are unique and non-empty.
