This is an experimental fork of the excellent but now-defunct Penumbra.
The original can be found at: https://github.com/ztellman/penumbra
So far, I’ve made 2 drastic changes:
1) It now depends on both Stuart Sierra’s Components and Prismatic Schema
{TODO: insert links}, because I’ve found both of them indispensable in
my day job
2) I’m in the process of switching it from LWJGL2 to LWJGL3.
The second step was drastic enough that I decided this deserves
its own life in its own repo.
I may never do anything meaningful with it, but that seems more likely
to happen this way.
From the original readme:
“Penumbra is an idiomatic wrapper for OpenGL in Clojure, by way of LWJGL.”
My original README {TODO: get this updated}:
This version of Penumbra is a fork that is really just an attempt to
get OpenGL working with clojure on my system. I’ve merged changes
from https://github.com/mortuosplango/penumbra and
https://github.com/kephale/penumbra, which seem to be the closest thing
to people who are putting any effort at all into maintaining this truly
amazing project.
Bare-bones example (I’m at least halfway reverse-engineering at this
point, so bear with me on this):
lein deps
lein repl
> (require ’[penumbra.example.opengl.gears :as gears])
nil
> (gears/start)
→ Should get a sample window drawing a rotating gear. Pressing the ESC
key while the window’s focused will cause it to exit. I get a long
java stack trace from a NullPointerException that happens.
At this point, we can probably all profit by reading ztellman’s
original documentation and source code. I really only created this
fork so I’d have something to play with while I’m working my way
through that, and the native dependencies just were not working.
(I’m thankful that kephale seems to have actually taken care of
that problem for me).
