// See FloatPointsKdTreeEncoder and DynamicIntegerPointsKdTreeEncoder for more
// details. Currently, the input PointCloud must satisfy the following
// 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.
