# Chendu v0.2

This is an early release of Chendu that demonstrates a new algorithm to compress 3D surface data.

In this demo, the digital elevation data set from LRO (Lunar Reconnaissance Orbiter) can be explored.

In this version, only the coarse data from the Spherical Harmonic Dataset is available.

## How to run

You will need to install Java 8 first.

Then run this command:

```
> java -jar chendu-assembly-0.2.jar
```

You should see a window that renders the Moon in 3D. To move around, try these keys:

* W, S to move forward / backward
* w, a, s, d : to pan
* q, r : to rotate
* i, k to turn up / down
* [, ], {, } : play with lights
