How to use

- Include THREE.FBOHelper.js. There's an ES6 build and an ES5 build transpiled with babel-cli in /build.
- Create a helper linked to a WebGLRenderer
``js
var helper = new FBOHelper( renderer );
`
or use npm to install the package:
`
npm i three.fbo-helper
`
and include it in your code (remember to include three.js too)
`js
var THREE = require( 'three' );
var FBOHelper = require( 'three.fbo-helper' );
`
- Call .setSize to adjust to the renderer size (don't forget to do onResize!)
`js
helper.setSize( width, height );
`
- Attach WebGLRenderTargets at discretion
`js
helper.attach( fieldFBO, 'Distance Field' );
helper.attach( particleFBO, 'Particles' );
`
`attach()` admits a third parameters, `formatter`, a function that will receive an object with the values of the current point `x`, `y`, `u`, `v`, `r`, `g`, `b`, and `a`. You can return a custom string in case you want to show a different caption in the label. Otherwise, it will show all the values.
Example:
`js
helper.attach( buffer, 'Particles', function( d ) {
return Position: (${d.x}, ${d.y}, ${d.z}) | Life: ${d.a};
} );
`
- Update with your animation loop
`js
helper.update();
`
- If for any reason you resize the FBO, call:
`js
helper.refreshFBO( fbo );
``

- Call `.detach` to remove any fbo previously attached
`js
helper.deatch( fbo );
```

Once the helper is working, you can select FBOs to inspect, and drag the viewer around and use the scroll/mousewheel to zoom in and out.
