				// requirements to use this encoder:
				// 1. PointCloud has only one attribute of type GeometryAttribute::POSITION.
				// 2. The position attribute has three components (x,y,z).
				// 3. The position values are stored as either DT_FLOAT32 or DT_UINT32.
				// 4. If the position values are stored as DT_FLOAT32, quantization needs to
				// be enabled for the position attribute.
