Abstract: A point cloud encoding method is provided. The method includes the following. A residual value of attribute information of a current point in a point cloud is determined according to a prediction value of the attribute information of the current point. An index of the current point is determined. Lossless encoding is performed on the residual value of the attribute information of the current point, when the index of the current point belongs to an index range of a first point. A quantized residual value of the attribute information of the current point is obtained by quantizing the residual value of the attribute information of the current point based on a quantization weight of the current point and a quantization step size of the current point, when the index of the current point is beyond the index range of the first point, and the quantized residual value is encoded.

Abstract: An encoding method includes following operations. Neighbouring points of a current point in a point cloud to be encoded are determined, and a first parameter is calculated according to the neighbouring points. The first parameter is a difference between a maximum value and a minimum value among reconstructed values of first attributes of the neighbouring points. In response to the first parameter being less than a threshold, a prediction value of the first attribute of the current point is determined by using a preset first prediction mode. A difference between an original value of the first attribute of the current point and the prediction value is calculated as a residual value of the first attribute of the current point. The residual value subjected to quantization is encoded. Identification information of the first prediction mode is signalled, where the identification information is used for indicating a prediction mode.

Abstract: A print driver store is usable for redirection printing in a virtualized computing environment that supports virtual desktops. Native print drivers are uploaded to the print driver store from a client side. When an agent attempts to instantiate a virtual printer at the agent side that corresponds to a physical printer at the client side, the agent checks to determine if a native print driver for the physical printer is installed at the agent side. If the native print driver is not installed, then the agent obtains the native print driver from the print driver store and installs the native print driver at the agent side. The agent completes the instantiation of the virtual printer at the agent side and associates the native print driver with the virtual printer.
