	<span>Creating a scene
	</span></h1>

<p>This section describes how to create and save a simple scene. The code in this section is reflected in <a href="https://github.com/huggingface/simulate/blob/main/examples/basic/create_and_save.py" rel="nofollow">examples/basic/create_and_save.py</a>.</p>
<p>Start by creating an empty scene:</p>

	<div class="code-block relative"><div class="absolute top-2.5 right-4"><button class="inline-flex items-center relative text-sm focus:text-green-500 cursor-pointer focus:outline-none transition duration-200 ease-in-out opacity-0 mx-0.5   text-gray-600 " title="code excerpt" type="button"><svg class="" xmlns="http://www.w3.org/2000/svg" aria-hidden="true" fill="currentColor" focusable="false" role="img" width="1em" height="1em" preserveAspectRatio="xMidYMid meet" viewBox="0 0 32 32"><path d="M28,10V28H10V10H28m0-2H10a2,2,0,0,0-2,2V28a2,2,0,0,0,2,2H28a2,2,0,0,0,2-2V10a2,2,0,0,0-2-2Z" transform="translate(0)"></path><path d="M4,18H2V4A2,2,0,0,1,4,2H18V4H4Z" transform="translate(0)"></path><rect fill="none" width="32" height="32"></rect></svg>

<span class="hljs-title">scene</span> = sm.<span class="hljs-type">Scene</span>()<!-- HTML_TAG_END --></pre></div>
<p>Then, add a light source and a box to the scene:</p>

<p>A full list of available built-in objects can be found <a href="https://github.com/huggingface/simulate/blob/main/examples/basic/objects.py" rel="nofollow">here</a>.</p>
<p>You can save the scene using the <a href="https://registry.khronos.org/glTF/specs/2.0/glTF-2.0.html" rel="nofollow">glTF 2.0</a> specification, allowing it to be shared across multiple platforms:</p>

<p>Finally, call <code>show()</code> to display the scene:</p>
