<a-triangle>

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 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>
