<h3>[method:null computeBoundingBox]()</h3>
<div>Computes bounding box of the geometry, updating [page:Geometry Geometry.boundingBox] attribute.</div>
<p>Computes bounding box of the geometry, updating [page:Geometry Geometry.boundingBox] attribute.</p>
<h3>[method:null computeBoundingSphere]()</h3>
<div>Computes bounding sphere of the geometry, updating [page:Geometry Geometry.boundingSphere] attribute.</div>
<p>Computes bounding sphere of the geometry, updating [page:Geometry Geometry.boundingSphere] attribute.</p>
<div>
<p>
Neither bounding boxes or bounding spheres are computed by default. They need to be explicitly computed,
otherwise they are *null*.

<p>Computes [page:Face3.normal face normals].</p>
<h3>[method:null computeFlatVertexNormals]()</h3>
<div>Computes flat [page:Face3.vertexNormals vertex normals]. Sets the vertex normal of each vertex of each face to be the same as the face's normal.</div>

"Interleaved" means that multiple attributes, possibly of different types, (e.g., position, normal, uv, color) are packed into a single array buffer.
