6.20 CREATION

The CREATION method is a "procedural" object creation tool. This means that it can create new objects during animations. As a matter of fact, it can control the whole process of "birth and death". For example, phenomena like boiling water or fireworks are perfect applications for this method.

The CREATION method accepts any number of parameter objects. The method uses the parameter objects as a samples for creating new copies. The copies are inserted to the same hierarchy level with the method itself so that they will be targets of it. The method can also delete target objects.

The rules controlling this process are mainly defined using two tags associated with parameters and/or target objects: SCRE and SDEL.

Whenever the tag SCRE is found from a parameter object, it is evaluated and the value of the "l" variable is used for determining whether or not a copy of the object should be created. If the value is zero (or if there is no SCRE tag associated with the parameter object), the copy is not created.

If the tag SDEL is included in the target object and if the value of the variable "l" is other than zero, the target object is deleted.
