NAME¶
glBindTransformFeedback - bind a transform feedback object
C SPECIFICATION¶
void
glBindTransformFeedback(GLenum target,
GLuint id);
PARAMETERS¶
target
Specifies the target to which to bind the
transform feedback object id. target must be
GL_TRANSFORM_FEEDBACK.
id
Specifies the name of a transform feedback
object reserved by glGenTransformFeedbacks().
DESCRIPTION¶
glBindTransformFeedback binds the transform feedback object with name
id to the current GL state.
id must be a name previously
returned from a call to
glGenTransformFeedbacks(). If
id has not
previously been bound, a new transform feedback object with name
id and
initialized with with the default transform state vector is created.
In the initial state, a default transform feedback object is bound and treated
as a transform feedback object with a name of zero. If the name zero is
subsequently bound, the default transform feedback object is again bound to
the GL state.
While a transform feedback buffer object is bound, GL operations on the target
to which it is bound affect the bound transform feedback object, and queries
of the target to which a transform feedback object is bound return state from
the bound object. When buffer objects are bound for transform feedback, they
are attached to the currently bound transform feedback object. Buffer objects
are used for trans- form feedback only if they are attached to the currently
bound transform feedback object.
ERRORS¶
GL_INVALID_ENUM is generated if
target is not
GL_TRANSFORM_FEEDBACK.
GL_INVALID_OPERATION is generated if the transform feedback operation is
active on the currently bound transform feedback object, and that operation is
not paused.
GL_INVALID_OPERATION is generated if
id is not zero or the name of
a transform feedback object returned from a previous call to
glGenTransformFeedbacks(), or if such a name has been deleted by
glDeleteTransformFeedbacks().
ASSOCIATED GETS¶
glGet() with argument
GL_TRANSFORM_FEEDBACK_BINDING
