# WebGL Volume Raycaster

A scientific visualization style volume raycaster written

using WebGL2 and Javascript. The renderer uses an arcball camera which supports

mouse or touch input, and dynamically adjusts the sampling rate

to maintain a smooth framerate, even on mobile devices. The volumes

are downloaded via XMLHttpRequest from Dropbox when selected.

[Try it out online!](https://www.willusher.io/webgl-volume-raycaster/)

I've also written a [blog post](https://www.willusher.io/webgl/2019/01/13/volume-rendering-with-webgl)

about how this renderer is implemented.

Uses [webgl-util](https://github.com/Twinklebear/webgl-util) for some WebGL utilities and [glMatrix](http://glmatrix.net/) for matrix/vector operations.
