<a-triangle>

Note: This documentation is for the old 1.5.0 version of A-Frame. Check out the documentation for the current 1.6.0 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>
