In response to receiving a content partial information response from the content provider IHS over a network, the caching engine generates a content-provider-side key using header information in the content partial information response. The caching engine performs a hashing operation on the content request using a combination of the user-side key and the content-provider-side key to produce a hashed content request, and uses the hashed content request to retrieve content from the cache. |

Point cloud data compression using a space-filling curve
Techniques of data compression involve ordering the points of a point cloud according to distance along a space-filling curve. Advantageously, a space-filling curve has the property that points close in distance along the curve are close together in Euclidean space. Thus, differences between points ordered by distance along such a curve, e.g., a Hilbert curve, will be close. When the curve is fractal, i.e., self-similar at all levels, the differences will be small even when the points are very unevenly clustered throughout the point cloud. Such small differences will provide greatly improved compression to the resulting delta-encoded set of points. |
