Class NVTransformFeedback2

java.lang.Object
org.lwjgl.opengl.NVTransformFeedback2
public class NVTransformFeedback2 extends Object
Native bindings to the NV_transform_feedback2 extension.

The NV_transform_feedback and EXT_transform_feedback extensions allow applications to capture primitives to one or more buffer objects when transformed by the GL. This extension provides a few additional capabilities to these extensions, making transform feedback mode more useful.

First, it provides transform feedback objects encapsulating transform feedback-related state, allowing applications to replace the entire transform feedback configuration in a single bind call. Second, it provides the ability to pause and resume transform feedback operations. When transform feedback is paused, applications may render without transform feedback or may use transform feedback with different state and a different transform feedback object. When transform feedback is resumed, additional primitives are captured and appended to previously captured primitives for the object.

Additionally, this extension provides the ability to draw primitives captured in transform feedback mode without querying the captured primitive count. The command DrawTransformFeedbackNV() is equivalent to glDrawArrays(<mode>, 0, <count>), where count is the number of vertices captured to buffer objects during the last transform feedback capture operation on the transform feedback object used. This draw operation only provides a vertex count -- it does not automatically set up vertex array state or vertex buffer object bindings, which must be done separately by the application.

Requires OpenGL 1.5 and NV_transform_feedback or EXT_transform_feedback.
