## About

Potree is a free open-source WebGL based point cloud renderer for large point clouds.
It is based on the [TU Wien Scanopy project](https://www.cg.tuwien.ac.at/research/projects/Scanopy/)
and it was part of the [Harvest4D Project](https://harvest4d.org/).

## Getting Started

### Build and Run

Make sure you have [node.js](http://nodejs.org/) installed

Install all dependencies, as specified in package.json, 
then, install the gulp build tool:

    cd <potree_directory>
    yarn install
    yarn build:dev

Use the ```yarn build:dev``` command to 

* create ./dist 
* watch for changes to the source code and automatically create a new build on change
* start a web server at localhost:1234. 

```
gulp watch
```

Go to http://localhost:1234/examples/ to test the examples.

### Convert

Download [PotreeConverter](https://github.com/potree/PotreeConverter) and run it like this:

    ./PotreeConverter.exe C:/pointclouds/data.las -o C:/pointclouds/data_converted

Copy the converted directory into &lt;potreeDirectory&gt;/pointclouds/data_converted. Then, duplicate and rename one of the examples and modify the path in the html file to your own point cloud.

## Downloads

[PotreeConverter source and Win64 binaries](https://github.com/potree/PotreeConverter/releases)

## Showcase

Take a look at the [potree showcase](http://potree.org/wp/demo/) for some live examples.
