<a-cylinder>

The cylinder primitive is used to create tubes and curved surfaces.

Examples

The cylinder primitive is versatile and can be used to create different kinds of shapes:

<!-- Basic cylinder. -->
<a-cylinder color="crimson" height="3" radius="1.5"></a-cylinder>

<!-- Hexagon. -->
<a-cylinder color="cyan" segments-radial="6"></a-cylinder>

<!-- Pac-man. -->
<a-cylinder color="yellow" theta-start="50" theta-length="280" side="double"></a-cylinder>

<!-- Green pipe. -->
<a-cylinder color="green" open-ended="true"></a-cylinder>

In degrees, thetaStart defines where to start the arc and thetaLength defines where the arc ends.

Also, we can create a tube by making the cylinder open-ended, which removes the top and bottom surfaces of the cylinder such that the inside is visible. Then, we need a double-sided material to render properly:

<a-cylinder color="cyan" material="side: double" open-ended="true" rotation="90 0 0"></a-cylinder>
