Is there a DSA technique for transform feedback?

Question

The typical way I see transform feedback being used is:

    glGenBuffers(1, &tbo);
    glBindBuffer(GL_TRANSFORM_FEEDBACK_BUFFER, tbo);
    glBufferData(GL_TRANSFORM_FEEDBACK_BUFFER, sizeof(data), nullptr, GL_DYNAMIC_COPY);

However, new, DSA OpenGL eschews the binding points. Is there a DSA way to bind a buffer to the transform feedback binding point?

Answer 1

Binding points (and other state) are still important when doing actual draw calls (stuff like VAOs, UBOs, SSBOs and programs are still bound). It's only bind-to-edit that was eschewed.

In your case the most DSA way to do that would be:

glCreateBuffers(1, &tbo);
glNamedBufferData(tbo,sizeof(data), nullptr, GL_DYNAMIC_COPY);

glBindBuffer(GL_TRANSFORM_FEEDBACK_BUFFER, tbo);

Answer 2

There isn't a DSA way to bind buffers to the feedback buffer bindings. But that's because transform feedbacks are objects, and there is a DSA way to attach buffers to transform feedback objects:

GLuint buffer;
glCreateBuffers(1, &buffer);
//Fill in buffer's data.

GLuint feedback;
glCreateTransformFeedbacks(1, &feedback);
glTransformFeedbackBufferRange(feedback, 0, buffer, offset, size);

You can then bind feedback when you're ready to actually do your feedback operations into those buffers.
