<a-triangle>

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

Example

<a-scene>
<a-assets>
<img id="platform" src="https://i.imgur.com/mYmmbrp.jpg">
</a-assets>

<!-- Basic triangle. -->
<a-triangle color="#CCC" vertex-c="1 -1 0"></a-triangle>

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

Parallelizing to the Ground

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

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