GLLOADIDENTITY(3G)

📦 version 1.1, in centos-stream 9, fedora 43, fedora 44

✨ NAME ✨

okay so bestie, welcome to GLLOADIDENTITY(3G) — the OpenGL glow-up page 💅 and literally all it does is replace the current matrix with the identity matrix. that's it. that's the whole vibe. reset queen. 🎀

🌸 C SPECIFICATION 🌸

void glLoadIdentity( void )

no args, no returns, no drama. she takes nothing and gives you a clean slate. periodt. ✨

💖 DESCRIPTION 💖

so here's the tea 🍓: glLoadIdentity replaces the current matrix with the identity matrix. ngl it's semantically equivalent to calling glLoadMatrix with the identity matrix, which looks like this:

1 0 0 0
0 1 0 0
0 0 1 0
0 0 0 1

like, the most iconic grid of all time, the "i'm not touching anything, i'm just vibing" matrix 🦋 — but in some cases it is more efficient. so yeah, sometimes she's just faster. slay. 🔥

😭 ERRORS 😭

GL_INVALID_OPERATION is generated if glLoadIdentity is executed between the execution of glBegin and the corresponding execution of glEnd.

fr fr bestie do NOT try to do this inside a glBegin/glEnd block, she will literally throw hands and error out at you 💀 no cap. wait for the glEnd, i'm begging. 🙈

👑 ASSOCIATED GETS 👑

you can go snoop on stuff with glGet, with these arguments:

  • GL_MATRIX_MODE — peep which matrix mode you're in rn
  • GL_COLOR_MATRIX — the color matrix tea ☕
  • GL_MODELVIEW_MATRIX — modelview matrix check ✨
  • GL_PROJECTION_MATRIX — projection matrix reveal 🌈
  • GL_TEXTURE_MATRIX — texture matrix moment 🎀

🌟 SEE ALSO 🌟

go read these next, iykyk:

  • glMatrixMode(3G)
  • glMultMatrix(3G)
  • glPushMatrix(3G)

and that's the whole page, bestie 🫶 this was GLLOADIDENTITY(3G) from the 3G manual — like the little footer at the bottom of every page whispered, GLLOADIDENTITY(3G), over and over. mwah. go reset some matrices. you got this. 💜✨
