Writing a space warp plug-in involves creating instances of two key classes.
|
||||
One is derived from class WSMObject. (WSMObject stands for Word Space Modifier Object,
|
||||
just another name for Space Warp Object). The other class is subclassed off Modifier.
|
||||
These two classes work together. The space warp object handles the display and management
|
||||
of its user interface parameters, the display of the space warp node in the scene, and
|
||||
provides a world space orientation. The space warp modifier handles the actual deformation
|
||||
of the geometry of nodes bound to the space warp. Each node bound to the space warp
|
||||
will have a ModContext which we will store data in.
|

The following class is the WSMObject for the westwood skin modifier.
