Hi, I began to investigate a way to create a transformfeedback pipeline only using opengl 3 features.
TextureBuffer as the method bindbufferas wich seams promizing in order to promizing binding TBO as FeedbackBuffer. However according to the doc: Code: The GL_TRANSFORM_FEEDBACK_BUFFER buffer binding point may be passed to glBindBuffer, but will not directly affect transform feedback state. Instead, the indexed GL_TRANSFORM_FEEDBACK_BUFFER bindings must be used through a call to [b]glBindBufferBase or glBindBufferRange. [/b]This will affect the generic GL_TRANSFORM_FEEDBACK_BUFFER binding. So the glBindBuffer used in TextureBuffer::bindbufferas seams not sufficient to use transform feedback features. I may be wrong but would like others opinions Thank you!
