NAME

cgCreateArraySamplerState - create an array-typed sampler state definition

SYNOPSIS


  #include <Cg/cg.h>







  CGstate cgCreateArraySamplerState( CGcontext context,

                                     const char * name,

                                     CGtype type,

                                     int nelements );

PARAMETERS


context
The context in which to define the sampler state.
name
The name of the new sampler state.
type
The type of the new sampler state.
nelements
The number of elements in the array.

RETURN VALUES

Returns a handle to the newly created CGstate.

Returns NULL if there is an error.

DESCRIPTION

cgCreateArraySamplerState adds a new array-typed sampler state definition to context. All state in sampler_state blocks must have been defined ahead of time via a call to the cgCreateSamplerState manpage or cgCreateArraySamplerState before adding an effect file to the context.

Applications will typically call the cgSetStateCallbacks manpage shortly after creating a new state with cgCreateArraySamplerState.

ERRORS

CG_INVALID_CONTEXT_HANDLE_ERROR is generated if context is not a valid context.

CG_INVALID_PARAMETER_ERROR is generated if name is NULL or not a valid identifier, if type is not a simple scalar, vector, or matrix-type, or if nelements is not a positive number.

HISTORY

cgCreateArraySamplerState was introduced in Cg 1.4.
