plasio is a project byUday Verma andHoward Butler that implements pointcloud rendering capability in a browser. Specifically, it provides a functionalimplementation of theASPRS LAS format, and it can consumeLASzip-compressed data using LASzipNaCl module. Plasio isChrome-only atthis time, but it is hoped that other contributors can step forward to bring itto other browsers.

It is expected that most WebGL-capable browers should beable to support plasio, and it contains nothing that is explicitly Chrome-specific beyond the optional NaCL LASzip module. We just haven't tested it beyondMac and Windows Chrome Canary at this time.

http://plas.io contains a demo of the interface and supports both LAS and LAZ.

What does the name plasio mean?

Nothing.

What are future plans for the software?

We hope that plasio provides a significant enough capability that othersstart to contribute exploitation and visualization flourishes.

When will it support X, Y, or Z?

The software is its formative stages at this point, and pullrequests that provide new capabilities or fix signficant issuesare going to be the most persuasive way to impact its futuredevelopment.

Plasio uses theGulp build system:

npm install -g gulp

To setup the development environment, you can run:

npm install

This will download all dependencies required to setup the build system.

You can then build and stage files under thebuild directory by running:

gulp

While developing, you may run:

gulp develop

This will serve built files locally and open your default browser pointing to the index page. Any changes you make tosource files will fire gulp tasks that will keep thebuild directory up to date. The build system also usesgulp's live-reload plugin, which works great withGoogle Chrome's Live Reload extension.

The gulp file includes a task to publish directly to plas.io, however, you need AWS Access for that to work. You may direct plasioto your own AWS buckets, in which case you will have to editgulpfile.js to direct it likewise.

The publish task looks for~/.aws.json which should include two fields,key andsecret.

To publish to AWS simply run:

gulp publish
