NOTE: This version of the documentation tracks unstable development happening on A-Frame’s master branch. If you wish to try it out, grab the unstable build. Otherwise, head to the documentation for the current 1.7.0 version

The circle primitive creates circles surfaces using the geometry component with the type set to circle.

Example

<a-scene>
<a-assets>
<img id="platform" src="platform.jpg">
</a-assets>

<!-- Basic circle. -->
<a-circle color="#CCC" radius="20"></a-circle>

<!-- Textured circle parallel to ground. -->
<a-circle src="#platform" radius="50" rotation="-90 0 0"></a-circle>
</a-scene>

Parallelizing to the Ground

To make a circle parallel to the ground, rotate it around the X-axis:

<a-circle rotation="-90 0 0"></a-circle>
