getSceneCount

int getSceneCount()

Obtains the number of scenes where glTF data is imported.

返回:

Returns the number of scenes where glTF data is imported.

getDefaultSceneIndex

int getDefaultSceneIndex()

Obtains the default scene index.

返回:

Returns the default scene index if it is found; returns INVALID_INDEX if the default scene is not specified.

getThumbnailCount

int getThumbnailCount()

Obtains the number of available thumbnails.

返回:

Returns the number of available thumbnails.

getExternalUris

List<String> getExternalUris()

Obtains the URIs of the indexes of a parsed glTF file. The URIs are relative to getBaseUri(). For example, the URI can be the name of an image or .bin file used by the glTF file.

返回:

Returns the URIs of the indexes of the parsed glTF file.

getGltfUri

String getGltfUri()

Obtains the URI of the source glTF data.
