GLGENLISTS(3G)

πŸ“¦ version 24.3.3, in opensuse-leap 16.0

✨ GLGENLISTS β€” bestie, let's make a whole squad of display lists πŸ’–

okay so this is the 3G manual page, and we're talking about glGenLists from OpenGL. Sit down, hydrate, we're doing graphics 🫢


🌸 NAME 🌸

glGenLists β€” generate a contiguous set of empty display lists ✨

(it's giving "reserve me a block of names, I'm about to fill them with art")


πŸ’… C SPECIFICATION πŸ’…

GLuint glGenLists( GLsizei range )

look at that signature. one argument. one return value. minimalism, we love her πŸ‘‘


πŸŽ€ PARAMETERS πŸŽ€

  • range β€” the number of contiguous empty display lists you want generated. like, "gimme this many, and gimme them all lined up next to each other" πŸ¦‹

🌈 DESCRIPTION 🌈

okay so glGenLists has exactly one argument, and that's range. she returns an integer n such that range contiguous empty display lists β€” named n, n+1, ..., n+range -1 β€” get created. a little squad. a whole lineup. iconic behavior, no cap πŸ’œ

but here's the tea β˜• β€” and listen closely because this part matters:

if range is 0, or if there's no group of range contiguous names available, or if any error gets generated, then no display lists are generated at all, and 0 is returned. that's the vibe check failing. nothing for you. go home πŸ™ˆ


πŸ’€ ERRORS πŸ’€

  • GL_INVALID_VALUE is generated if range is negative. bestie. bestie why would you do that. negative range is not a thing. 😭
  • GL_INVALID_OPERATION is generated if glGenLists is executed between the execution of glBegin and the corresponding execution of glEnd. so like, don't try to generate lists while you're mid-drawing. that's the forbidden window. do not 🚫

πŸ”₯ ASSOCIATED GETS πŸ”₯

  • glIsList

(the little check-in function. "hey, are you a list? do you exist?" so cute) πŸ₯Ί


🌟 SEE ALSO 🌟

  • glCallList(3G)
  • glCallLists(3G)
  • glDeleteLists(3G)
  • glNewList(3G)

go read those too, they're all in the same friend group πŸ’ž


and that's the whole page, bestie ✨ the header up top said GLGENLISTS(3G) and the footer said GLGENLISTS(3G) again β€” it's from the 3G manual, the OpenGL one, and there's no extra date or version stamped on it, so that's just... the whole thing. short, sweet, and honestly a little mysterious πŸ’– go make some display lists. slay πŸŽ€
