What forces layout / reflow

All of the below properties or methods, when requested/called in JavaScript, will trigger the browser to synchronously calculate the style and layout*. This is also called reflow or layout thrashing, and is common performance bottleneck.

Generally, all APIs that synchronously provide layout metrics will trigger forced reflow / layout. Read on for additional cases and details.

Element APIs

Getting box metrics

• elem.offsetLeft, elem.offsetTop, elem.offsetWidth, elem.offsetHeight, elem.offsetParent

Weird Idea

UPDATE working on this here!

so… I've had this weird idea recently...

In git (and in other secure + distributed systems) you have a tree of hashes where each object is identified by it's hash and objects contain pointers to other objects. They just have the hash of other objects stored inside them.

Each of these commands will run an ad hoc http static server in your current (or specified) directory, available at http://localhost:8000. Use this power wisely.

Terminology

• block/voxel/cube -> mostly interchangeable. The minecrafty blocks you see on the screen.
• chunk: is a piece of the world that contains voxels
• AABB: bounding volume
• voxeljs: not 100% consistent yet, 'voxel.js' also acceptable, but definitely not 'VoxelJS'.
• dims: short for 'dimensions'. Perhaps obvious to some.
