CLOUD

Purpose:

To modify the shape of an existing Cloud primitive. For terminology, refer to the documentation of cloud primitive creation.

The shape of the cloud is modified by adjusting the underlying control polygon in one of two ways:

• by moving a node

• by moving a side

Instructions:

1. In the Modify menu, click Cloud.

2. You are now prompted to indicate a cloud to modify. Once the cloud primitive has been identified, it will be highlighted and the user is prompted to indicate the node or side of the polygon to move:

   • If a node is indicated, it is highlighted and the user is asked to supply a new position for that node.

   • If a side is indicated, it is dragged into desired position by the user, along a direction perpendicular to that side

     Once the new position has been given, the shape of the cloud contour is recreated according to the resulting polygon.

3. When satisfied with the shape, click Operation Complete.

Options:

None.

Result:

User-indicated cloud primitives will be modified according to user's action.
