- <h2>Methods</h2>
- <h3>.applyMatrix( [page:Matrix4 matrix] )</h3>
- <div>
- Bakes matrix transform directly into vertex coordinates.
- </div>
- <h3>.computeCentroids()</h3>
- <div>
- Computes centroids for all faces.
- </div>
- <h3>.computeFaceNormals()</h3>
- <div>
- Computes face normals.
- </div>
- <h3>.computeVertexNormals()</h3>
- <div>
- Computes vertex normals by averaging face normals.<br />

- </div>
- <h3>.computeMorphNormals()</h3>
- <div>
- Computes morph normals.
- </div>
- <h3>.computeTangents()</h3>
- <div>
- Computes vertex tangents.<br />
- Based on [link:http://www.terathon.com/code/tangent.html]<br />
- Geometry must have vertex [page:UV UVs] (layer 0 will be used).
- </div>
- <h3>.computeBoundingBox()</h3>
- <div>
- Computes bounding box of the geometry, updating [page:Geometry Geometry.boundingBox] attribute.
- </div>
- <h3>.computeBoundingSphere()</h3>
- <div>
- Computes bounding sphere of the geometry, updating [page:Geometry Geometry.boundingSphere] attribute.
- </div>
-
- <div>Neither bounding boxes or bounding spheres are computed by default. They need to be explicitly computed, otherwise they are *null*.</div>
- <h3>.mergeVertices()</h3>
- <div>
- Checks for duplicate vertices using hashmap.<br />
- Duplicated vertices are removed and faces' vertices are updated.
- </div>
-
- <h3>.clone()</h3>
- <div>
- Creates a new clone of the Geometry.
- </div>
-
- <h3>.dispose()</h3>
- <div>
- Removes The object from memory. <br />
- Don't forget to call this method when you remove an geometry because it can cuase meomory leaks.
