OVRGLTFAccessor Class
Extends
IDisposable
Helper class used by OVRGLTFLoaderto load GLTF (GL Transmission Format) data buffers using appropriate accessors and translates them into corresponding Unity data types when applicable.
This class follows the GLTF 2.0 specification for loading data. For more information, refer to the Binary Data Storage section on the GLTF 2.0 specification site.
This class is intended to be used in conjunction with the . It is not recommended to use these functions outside of the context of GLTF loading.

Seek
(
accessorIndex
, onlyBufferView
)
|
Indexes into the GLTF accessors JSONNode provided to the TryCreate method and moves the binary data stream position based on the accessor's data.
Signature
void Seek(int accessorIndex, bool onlyBufferView=false) Parameters accessorIndex: int
The index to a accessor in the accessor array.
onlyBufferView: bool
If the position should be set to just the start of the buffer view.
Returns void |
Static Methods
TryCreate
(
accessorsRoot
, bufferViewsRoot
, buffersRoot
, binaryChunk
, dataAccessor
)
|
Tries to create a OVRGLTFAccessor object by checking if the binary stream data provided is a valid GLTF binary chunk.
