Name

cgCreateSamplerState - create a sampler state definition

Synopsis

#include <Cg/cg.h>

CGstate cgCreateSamplerState( CGcontext context,
                              const char * name,
                              CGtype type );

Parameters

context
The context in which to define the new sampler state.
name
The name of the new sampler state.
type
The type of the new sampler state.

Return Values

Returns a handle to the newly created CGstate.

Returns NULL if there is an error.

Description

cgCreateSamplerState adds a new sampler state definition to the context. When an effect file is added to the context, all state in sampler_state blocks must have already been defined via a call to cgCreateSamplerState or cgCreateArraySamplerState.

Applications will typically call cgSetStateCallbacks shortly after creating a new state with cgCreateSamplerState.

Examples

to-be-written

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, or if type is not a simple scalar, vector, or matrix-type. Array-typed state should be created with cgCreateArrayState.

History

cgCreateSamplerState was introduced in Cg 1.4.
