GLTRANSFORMFEEDBACKB(3G)

💅 GLTRANSFORMFEEDBACKB

okay so literally the manual page name is GLTRANSFORMFEEDBACKB(3G) — the (3G) is the manual section bestie, that's the OpenGL one 🎀 — and today we're learning how to glue a buffer object onto a transform feedback buffer object. it's giving binding energy ✨

---

✨ NAME ✨

glTransformFeedbackBufferBase — bind a buffer object to a transform feedback buffer object. that's the whole job. one job. she does it well 💖

---

🌸 C SPECIFICATION 🌸

void glTransformFeedbackBufferBase(GLuint xfb, GLuint index,
                                   GLuint buffer);

look at her. three parameters. no notes. iconic. 👑

---

🦋 PARAMETERS 🦋

• xfb — the name of the transform feedback buffer object. this is the one we're decorating bestie 💅
• index — the index of the binding point within xfb. like which little hook on the rack we're hanging this on.
• buffer — the name of the buffer object to bind to that specified binding point. the actual thing being hung up 🎀

---

💜 DESCRIPTION 💜

glTransformFeedbackBufferBase binds the buffer object buffer to the binding point at index index of the transform feedback object xfb. literally that's it. no cap. assignment complete. 🫶

---

🌈 NOTES 🌈

calling glTransformFeedbackBufferBase is equivalent to calling glTransformFeedbackBufferRange() with offset zero and size equal to the size of buffer. so like, same result, different outfit. iykyk ✨

---

🔥 ERRORS 🔥

• GL_INVALID_OPERATION is generated if xfb is not the name of an existing transform feedback object. (bestie that object does not exist 😭)
• GL_INVALID_VALUE is generated if in buffer is not zero or the name of an existing buffer object. yeah the original says "if in buffer" — i'm not touching it, that's the canonical text, we respect the source in this house 🫡
• GL_INVALID_VALUE is generated if index is greater than or equal to the number of transform feedback buffer binding points (that number is the value of GL_TRANSFORM_FEEDBACK_BUFFER_BINDING). out of range = no ❌

---

⭐ VERSION SUPPORT ⭐

so the original has a whole giant grid here, and since we're in a terminal we're doing it as a list. same facts, cuter delivery 💖

which OpenGL versions support glTransformFeedbackBufferBase? brace yourself:

• OpenGL 2.0 — -
• OpenGL 2.1 — -
• OpenGL 3.0 — -
• OpenGL 3.1 — -
• OpenGL 3.2 — -
• OpenGL 3.3 — -
• OpenGL 4.0 — -
• OpenGL 4.1 — -
• OpenGL 4.2 — -
• OpenGL 4.3 — -
• OpenGL 4.4 — -
• OpenGL 4.5 — ✔

so basically 4.5 only. she's a late bloomer and that's fine, she's thriving 🌸👑
