vpCreateContext(3)

💖 vpCreateContext(3) 💖

okay bestie, so this is a page from the Library Functions Manual and it's all about the two functions that bring a rendering context into existence and then yeet it back out. we love a lifecycle moment. 🦋

✨ NAME ✨

vpCreateContext, vpDestroyContext — create/destroy a rendering context 🎀

✨ SYNOPSIS ✨

#include <volpack.h>

vpContext *
vpCreateContext()

void
vpDestroyContext(vpc)
    vpContext *vpc;

✨ ARGUMENTS ✨

• vpc — the VolPack context you got from vpCreateContext. that's the one, that's the girl. 💅

✨ DESCRIPTION ✨

vpCreateContext returns a handle for a new rendering context. brand new, fresh out the box, no notes. and here's the slay part: it already comes loaded with default values for most of the rendering parameters, so you're not starting from absolute scratch. it's giving prepared. it's giving organized. 👑

vpDestroyContext destroys a rendering context and frees the associated memory. goodbye, farewell, rest in peace, periodt. 🫶

but listen — lowkey important, don't skip this part:

Only data structures allocated by the library are freed. application-defined data structures that are referenced in the rendering context through a pointer are not freed — like arrays of volume data and shading lookup tables. those are yours.

so the application is responsible for keeping track of those data structures and freeing them when appropriate. not the library's problem, bestie. it's your mess, you clean it up. 😭 the library said "not my circus, not my monkeys" fr fr.
