The + * shader variable attrName is implicitly set to the + * value of the corresponding Java 3D system attribute + * j3dAttrName during rendering. attrName + * must be the name of a valid uniform attribute in the shader in + * which it is used. Otherwise, the attribute name will be ignored and + * a runtime error may be generated. j3dAttrName must be + * the name of a predefined Java 3D system attribute. An + * IllegalArgumentException will be thrown if the specified + * j3dAttrName is not one of the predefined system + * attributes. Further, the type of the j3dAttrName + * attribute must match the type of the corresponding + * attrName variable in the shader in which it is + * used. Otherwise, the shader will not be able to use the attribute + * and a runtime error may be generated. + * + *

+ * Following is the list of predefined Java 3D system attributes:
+ * + *

+ * + *

+ * Depending on the shading language (and profile) being used, several + * Java 3D state attributes are automatically made available to the + * shader program as pre-defined uniform attributes. The application + * doesn't need to do anything to pass these attributes in to the + * shader program. The implementation of each shader language (e.g., + * Cg, GLSL) defines its own mapping from Java 3D attribute to uniform + * variable name. + * + *

+ * A list of these attributes for each shader language can be found in + * the concrete subclass of ShaderProgram for that shader language. + * + *
