 # hackvr-turbo

-Implementation of epochs hackvr
+Implementation of [epochs HackVR](https://github.com/kkabrams/hackvr) project.

+## Current status
+
+- Basic rendering works
+- Commands implemented:
+  - `addshape`
+  - `move` (partially)
+  - `rotate` (partially)
+  - `renamegroup`
+- Std-I/O works
+
+## Controls
+
+Use *Up* and *Down* to move forward/backward, *Left* and *Right* to rotate the camera. Use *Alt* to change *Left*/*Right* to strafing.
+*W*,*A*,*S*,*D* can also be used to move the camera (strafing + forward).
+
+With *Page Up* and *Page Down* you can look up/down, using *Alt* allows to move the camera up or down.
+
+Right click with the mouse and drag to rotate the camera. Use the left mouse button to trigger a `action` output to stdout.
+
+## Quick Start
+
+Build the project (see below), then run this:
+```sh
+cat ./lib/hackvr/data/test.hackvr | ./zig-cache/bin/hackvr
+```
