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.
