Defines a model loader, which is a Java class responsible for loading a model into memory given an URL to the model, or given a string representation of the model.
-
id - An unique identifier within the declaring plug-in for the loader. This is typically a value that begins with a letter is is followed by a sequence of letters, numbers, hyphens(-) and underscores(_). This value is prefixed with the declaring plug-in id and a period (.) to form a fully qualified identifier for the model loader.
-
name - A descriptive name for the model loader.
-
class - A class that implements the model loader.
-
dynamicTypes - Indicates whether the model loader dynamically determines whether it handles a particular file type. If 'true', then the model loader must implement IModelLoader.canLoad(String). If 'false', then the types supported by the model loader are determined by child <type> elements, and by <loadableType> elements.
<!ELEMENT defaultTypeLoader EMPTY>
<!ATTLIST defaultTypeLoader
fileType CDATA #REQUIRED
id CDATA #REQUIRED>
Defines the default model loader for a given file type.
-
fileType - The file type (extension) for which the default loader is being defined.
-
id - The fully qualified id of the model loader.
<!ELEMENT loadableType EMPTY>
<!ATTLIST loadableType
fileType CDATA #REQUIRED
id CDATA #REQUIRED>
Extends the types supported a Model Loader. This element may be used by plug-ins other than the plug-in declaring the model loader.
-
fileType - The file type that is loadable.
-
id - The fully qualified id of the model loader that is capable of loading the type. This is the id of the plug-in defining the model loader, followed by a period (.) and the id of the model loader (from the <loader>) element.
<!ELEMENT type EMPTY>
<!ATTLIST type
fileType CDATA #REQUIRED>
Defines a file type that is understood by the model loader.
-
fileType - A file type (file extension).
