textgl

An OpenGL ES 1.0 and EGL 1.0 implementation that renders to an ASCII console.

Lets get the obvious stuff out of the way.

Who?

Me. Joshua Minter. Here's my website.

What?

There's a description above. Don't be so lazy.

When?

Now.

Where?

Here.

Why?

I was VERY bored.

How to build

To build it you will need make and tup installed. The following make rules are available:

• debug (default): builds the project with tup
• release: builds the project with release settings
• clean: cleans the project using git to delete ignored files
• verbose: prepend other rules to make tup verbose

VS Code support

If you use VS Code, I have provided some config files so you can press F5 to build and debug tests (that currently do not exist ¯\_(ツ)_/¯).

Files and status

Based on this reference. Also this list is a bit old, I need to fix it up after the project is a bit more stable and clean (right now its a bit of a mess as I switch between ideas).
