# Geometer

In my continuing effort to get the [Clojure](http://clojure.org)
community to notice [Karsten Schmidt](http://postspectacular.com), and
the creative coding community to notice Clojure, I've created this
little interactive playground for experiments with Karsten's
[th.ing](https://github.com/thi-ng) libraries. A live version is
hosted [here](http://proscenium.rusher.com/geometer/).

## Usage

* Select model to generate from pallette
* Switch between normal & stereo rendering modes

### Keyboard shortcuts

* `w` / `s` - zoom in/out
* `[` / `]` - adjust eye separation for stereo rendering mode (see HUD
  in top-right corner)

Since it's hard to determine the correct eye separation without a VR
device, with my cross-eyed experiments, I believe the sweetspot is at
~ -0.31. It's best to use a simple object (e.g. cube) and also
somewhat zoom out. Once you see in stereo, then switch to more
exciting objects (e.g. algae)...

## Getting Started

After checking out the repo (and assuming
[boot](https://github.com/boot-clj/boot) is installed):

1. Start the `boot` development server: `$ boot dev`

2. Point your browser of choice at `http://localhost:3000/`

3. Connect your editor to the `nrepl` server that `boot` started,
   which in `emacs` can done via `M-x cider-connect` ⇒ `localhost` ⇒
   `geometer:port-number`.

4. Refresh your browser to make sure all the bits are talking to each other.

5. If you're using `emacs`, `cider-eval-buffer`.

6. Begin evaluating forms.

N.B. Saving any `cljs` file will trigger recompilation of the entire file
and an automatic reload of the namespace. The current model and view
rotation are defined using `defonce` to avoid jankiness.

## The Code

There are examples of creating meshes from primitive shapes, including
extruding 3D meshes from 2D primitives, and implementations for a
couple of simple generative techniques. More will follow.
