Description

PQDCWP queries the workstation description table and returns a dynamic modification accepted flag for each of the following types of picture changes:

•Data mapping representation

•Reflectance representation

•Parametric surface representation

•Light source representation

•Depth cue representation

•Color mapping representation

These flags indicate to what extent a type of picture change is supported by the specified workstation. 

The flags can have the following values:

Value     Description
----------------------------------------------------------------------------
IMM       Digital PHIGS can perform all picture changes of this type
          immediately.
IRG       Digital PHIGS can execute some picture changes of this type
          only by performing an implicit regeneration.  In some cases,
          Digital PHIGS can execute some changes immediately.  For example,
          when no structures are posted, Digital PHIGS can usually execute
          most changes without an implicit regeneration.
CBS       Digital PHIGS can execute some picture changes of this type
          only by performing an implicit regeneration.  For these
          changes, Digital PHIGS provides a quick update method so it can
          simulate the picture change to achieve an indication of the
          effect without regeneration.  A completely correct effect
          still requires an implicit regeneration.
