GLENABLECLIENTSTATE(3G)

✨ GLENABLECLIENTSTATE ✨

okay bestie, welcome to GLENABLECLIENTSTATE(3G) — the section 3G OpenGL page about turning client-side capabilities on and off 💅 this is the one that flips the little switches so your arrays actually show up when you render. no cap.

🌸 NAME 🌸

glEnableClientState, glDisableClientState — enable or disable a client-side capability 🎀

---

💖 C SPECIFICATION 💖

void glEnableClientState( GLenum cap);  1.1 )

---

🦋 PARAMETERS 🦋

• 1.1 — specifies the capability to enable ✨. these symbolic constants are the ones that get accepted: GL_COLOR_ARRAY, GL_EDGE_FLAG_ARRAY, GL_INDEX_ARRAY, GL_NORMAL_ARRAY, GL_TEXTURE_COORD_ARRAY, and GL_VERTEX_ARRAY.

---

💜 C SPECIFICATION 💜

void glDisableClientState( GLenum cap);  1.1 )

---

🎀 PARAMETERS 🎀

• 1.1 — specifies the capability to disable 🌈.

---

⭐ DESCRIPTION ⭐

glEnableClientState and glDisableClientState are the duo that turn individual client-side capabilities on or off, one at a time 🫶. by default, every single client-side capability starts out disabled — so if your stuff isn't rendering, check this first, iykyk 😭.

both glEnableClientState and glDisableClientState take a single argument, 1.1, and that argument can be any one of these iconic values 👑

• GL_COLOR_ARRAY — if enabled, the color array is enabled for writing and gets used during rendering when glArrayElement, glDrawArrays, glDrawElement, or glDrawRangeElements is called. see glColorPointer. 🍓
• GL_EDGE_FLAG_ARRAY — if enabled, the edge flag array is enabled for writing and gets used during rendering when glArrayElement, glDrawArrays, glDrawElement, or glDrawRangeElements is called. see glEdgeFlagPointer. 🦋
• GL_INDEX_ARRAY — if enabled, the index array is enabled for writing and gets used during rendering when glArrayElement, glDrawArrays, glDrawElement, or glDrawRangeElements is called. see glIndexPointer. 🌸
• GL_NORMAL_ARRAY — if enabled, the normal array is enabled for writing and gets used during rendering when glArrayElement, glDrawArrays, glDrawElement, or glDrawRangeElements is called. see glNormalPointer. ⭐
• GL_TEXTURE_COORD_ARRAY — if enabled, the texture coordinate array is enabled for writing and gets used during rendering when glArrayElement, glDrawArrays, glDrawElement, or glDrawRangeElements is called. see glTexCoordPointer. 💖
• GL_VERTEX_ARRAY — if enabled, the vertex array is enabled for writing and gets used during rendering when glArrayElement, glDrawArrays, glDrawElement, or glDrawRangeElements is called. see glVertexPointer. 👑

🌈 NOTES 🌈

• glEnableClientState is available only if the GL version is 1.1 or greater. no old-school GL for this one, sorry bestie 🙈.
• if GL_ARB_multitexture is supported, enabling and disabling GL_TEXTURE_COORD_ARRAY affects the active client texture unit. that active client texture unit is controlled with glClientActiveTextureARB. 🧚

---

💀 ERRORS 💀

• GL_INVALID_ENUM is generated if 1.1 is not an accepted value. so like, don't just pass vibes in there ✋.

🚨 glEnableClientState is not allowed between the execution of glBegin and the corresponding glEnd — but an error may or may not be generated. and if no error is generated, the behavior is undefined. so fr fr, just don't do it. 😭

and that's the whole page, bestie 💅 the little footer down at the bottom just echoes the name right back at you — GLENABLECLIENTSTATE(3G) — no extra version or date tea to spill, it's literally just the title doing a lil encore. go enable some arrays and slay ✨🫶
