// Lookup Tables for Transvoxel's Modified Marching Cubes

// Unlike the original paper (Marching Cubes: A High Resolution 3D Surface Construction Algorithm), these tables guarantee
// a closed mesh "whose connected components are continuous and free of holes."
//
// Rotations are prioritised over inversions so that 3 of the 6 cases containing ambiguous faces are never added. 3 extra
// cases are added as a post-process, overriding inverses through custom-build rotations to eliminate the rest.

A metatable in Lua defines various extraneous behaviors for a table when indexed, modified, interacted with, etc. They are Lua's core metaprogramming feature; most well known for being useful to emulate classes much like an OOP language.

Any table (and userdata) may be assigned a metatable. You can define a metatable for a table as such:

-- Our sample table
local tab = {}
-- Our metatable
local metatable = {
 -- This table is then what holds the metamethods or metafields

CUSTOM GAME ENGINES: A Small Study

WARNING: Article moved to separate repo to allow users contributions: https://github.com/raysan5/custom_game_engines

A couple of weeks ago I played (and finished) A Plague Tale, a game by Asobo Studio. I was really captivated by the game, not only by the beautiful graphics but also by the story and the locations in the game. I decided to investigate a bit about the game tech and I was surprised to see it was developed with a custom engine by a relatively small studio. I know there are some companies using custom engines but it's very difficult to find a detailed market study with that kind of information curated and updated. So this article.

Nowadays lots of companies choose engines like [Unreal](https:

Minimal D3D11

Minimal D3D11 reference implementation: An uncluttered Direct3D 11 setup + basic rendering primer and API familiarizer. Complete, runnable Windows application contained in a single function and laid out in a linear, step-by-step fashion that should be easy to follow from the code alone. ~200 LOC. No modern C++, OOP or (other) obscuring cruft. View on YouTube

Plex Media Permissions for Linux Noobies

There is no problem with being a noobie and I do not use the term to sligtht or disparage anyone.

This is a way to setup your permissions for running Plex in Linux. Different folks may use different methods.

The permissions concepts provided here apply to OSX, but the users and groups are controlled and modified differently, so much of this will not work properly. I think the command is dscl, but that could be out of date.

There are many ways to setup your permissions scheme in Linux, this methodology describes a way to do it, not everyone will like it, but it works for me, so whatever.
