Function Documentation

VRAY_Procedural* allocProcedural

(

const char *

name

)

Mantra procedural primitives.

When a procedural is defined as a dynamic object, the allocProcedural() function is called to build a new instance of the procedural. The name passed in will be the name defined by the table entry. This can be used for: a) Error checking -- you can verify that you're name is what you expect. However, this isn't manditory. b) To have more than one procedural defined per C++ class. Using the name, you can create procedurals of different types.

The argument list for the procedural is specified by a list of arguments. The getProceduralArgs() method should return a pointer to an array of VRAY_ProceduralArg's. The list should be terminated by an entry with default arguments (i.e. null pointers). For example: Arguments can then be queried using the argValue() methods in the procedural Dynamic load entry point to create an instance
