The envelope type can be one of the following. typedef struct st_LWVParmFuncs LWVParmFuncs vparm = create( envtype, txtype ) Create a new vparm. The global function returns a pointer to an LWVParmFuncs. Vparmf = global( LWVPARMFUNCS_GLOBAL, GFUSE_TRANSIENT ) The variant parameters global supplies the implementation of the vparm data type. You're free to use them for other things as well. That's the rationale for the existence of vparms, but Vparms are used as containers for the values of XPanel controls that can be enveloped or textured (any control with A variant parameter, or vparm, is a double-precision variable or 3-vector that can varyĪs a function of time. ![]()
