- A class containing utility functions for [page:BufferGeometry BufferGeometry] instances.<br /><br />
- </p>
- <h2>Methods</h2>
- <h3>[method:null computeTangents]( [param:BufferGeometry geometry] )</h3>
- <p>
- geometry -- A [page:BufferGeometry BufferGeometry] instance, which must have index, position, normal, and uv attributes.<br /><br />
- Calculates and adds tangent attribute to a geometry.<br /><br />
- </p>
- <h3>[method:BufferGeometry mergeBufferGeometries]( [param:Array geometries], [param:Boolean useGroups] )</h3>
- <p>
- geometries -- Array of [page:BufferGeometry BufferGeometry] instances.<br />
- useGroups -- Whether groups should be generated for the merged geometry or not.<br /><br />
- Merges a set of geometries into a single instance. All geometries must have compatible attributes.
- If merge does not succeed, the method returns null.<br /><br />
- </p>
- <h3>[method:BufferAttribute mergeBufferAttributes]( [param:Array attributes] )</h3>
- <p>
- attributes -- Array of [page:BufferAttribute BufferAttribute] instances.<br /><br />
- Merges a set of attributes into a single instance. All attributes must have compatible properties
- and types, and [page:InterleavedBufferAttribute InterleavedBufferAttributes] are not supported. If merge does not succeed, the method
- returns null.
