Primitives

Primitives extend entities to:

• Introduce a syntax to something more familiar for newcomers to A-Frame.
• Alias <a-entity> into something more specific like <a-sphere>.
• Define a mapping from flat HTML attributes to inner-component properties.
• Introduce magic by allowing transformation of incoming HTML values.
• Bake certain components and component properties for a specific use case.

Example:

<a-box color="red" depth="5" height="2" width="3"></a-box>
<a-videosphere src="360.mp4"></a-videosphere>
