EMITSTREAMVERTEX(3G)

🦋 EMITSTREAMVERTEX(3G) 🦋

okay bestie, pull up a chair, because we're doing EmitStreamVertex(3G) — yes, the GLSL one, section 3G of the manual, the one that lives in your Geometry Shader era 💅. She's niche, she's specific, and she's about to eat.

---

✨ NAME ✨

EmitStreamVertex — emit a vertex to a specified stream 🎀

---

🌸 DECLARATION 🌸

void EmitStreamVertex(int stream);

periodt, that's the whole signature, no cap 🔥

---

💜 PARAMETERS 💜

• stream — specifies the stream upon which the vertex will be emitted. that's it, that's the parameter, she's a single-arg icon 👑

---

🌈 DESCRIPTION 🌈

So here's the tea, and it's Geometry Shader exclusive — EmitStreamVertex is available only in the Geometry Shader, so don't even try to sneak her into your vertex shader, she will not come. 🙈

What she does: she emits the current values of your output variables to the current output primitive on stream stream. Like, you point at a stream, she yeets the vertex there. main character energy fr fr.

🚨 the argument stream must be a constant integral expression. not a vibe, not a variable, a constant integral expression. okay? okay. 💅

And then the spicy part — the way that, on return from this call, the value of all output variables for all streams are undefined. undefined!! 😭 so don't be out here reading your outputs after the call expecting them to be cute, because they're not, they're in the void. all streams. every one. 💀

⭐ VERSION SUPPORT ⭐

Here's the glow-up timeline for EmitStreamVertex across the OpenGL Shading Language versions, in all her ✨not-supported-then-suddenly-very-supported✨ glory:

• 1.10 — - (nope, not yet 🥲)
• 1.20 — -
• 1.30 — -
• 1.40 — -
• 1.50 — -
• 3.30 — -
• 4.00 — ✔ (HELLO?? she's here!! 🎉)
• 4.10 — ✔
• 4.20 — ✔
• 4.30 — ✔
• 4.40 — ✔
• 4.50 — ✔

so basically she shows up in 4.00 and never leaves. iconic behaviour honestly 🫶
