NAME
cgCreateSamplerState - create a new sampler state definition
SYNOPSIS
#include <Cg/cg.h> CGstate cgCreateSamplerState(CGcontext cgfx, const char *name, CGtype type);PARAMETERS
- ctx
Specifies the context to define the sampler state in.
- name
Specifies the name of the new sampler state.
- type
Specifies the type of the new sampler state.
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 in must have been defined ahead of time via a call to cgCreateSamplerState or cgCreateArraySamplerState.
Applications will typically call cgSetStateCallbacks shortly after creating a new state with cgCreateSamplerState.
RETURN VALUES
cgCreateSamplerState returns a handle to the newly created CGstate. If there is an error, NULL is returned.
ERRORS
CG_INVALID_CONTEXT_HANDLE_ERROR is generated if ctx does not refer to a valid context.
CG_INVALID_PARAMETER_ERROR is generated if name is NULL or not a valid identifier, as well as if type is not a simple scalar, vector, or matrix-type. (Array-typed state should be created with cgCreateArrayState.)
