Method and apparatus for rendering a computer generated image
A method and apparatus for rendering a computer-generated image using a stencil buffer is described. The method divides an arbitrary closed polygonal contour into first and higher level primitives, where first level primitives correspond to contiguous vertices in the arbitrary closed polygonal contour and higher level primitives correspond to the end vertices of consecutive primitives of the immediately preceding primitive level. The method reduces the level of overdraw when rendering the arbitrary polygonal contour using a stencil buffer compared to other image space methods. A method of producing the primitives in an interleaved order, with second and higher level primitives being produced before the final first level primitives of the contour, is described which improves cache hit rate by reusing more vertices between primitives as they are produced. |

Curve antialiasing based on curve-pixel intersection
Curve antialiasing based on curve-pixel intersection is leveraged in a digital medium environment. For instance, to apply antialiasing according to techniques described herein, curves of a visual object are mapped from an original pixel space to a virtual pixel space. Virtual pixels of the virtual pixel space that are intersected by the mapped curves are identified and aggregated as intersected virtual pixels. The intersected virtual pixels are then mapped back into the original pixel space to identify which intersected virtual pixels positionally coincide with respective original pixels of the original pixel space. Intersected virtual pixels are mapped to original pixels to generate pixel coverage for original pixels. The generated pixel coverage values for original pixels are applied to render antialiased curves as part of an antialiased version of the original visual object. |

System for enhancing data transmission in a network environment
A data handling or patching system operates to reduce redundant data within a data storage. Data files are compared, and a data difference is output. In files that have very similar data, the data difference between values is relatively small, and thus when a basic data file and a data difference file are stored, data redundancy is significantly reduced. The data difference of “diff” file can then be used to losslessly reproduce the data of either of the compared files. A first or primary port is dedicated for base quality transmissions on which the broadcasting client sends the lowest available quality. Additional or secondary ports enable transmission of higher than base quality data, sent as “diff's” of the base quality. The receiving client combines the “diff” data on the secondary ports with the base data of the first port, to produce higher quality media. |

Automatic deployment of application security policy using application manifest and dynamic process analysis in a containerization environment
A policy interpreter detects that an application container has been added in a container system, and opens a stored manifest for the application container.

When at least one subprocess calls a system call to enter a blocking I/O, a marking operation is performed, the kernel issues a first notification event to a network simulator, to request the network simulator to pause until the subprocess leaves from the blocking I/O. when the kernel detects that the subprocess leaves from the blocking I/O already, the kernel issues a second notification event to the network simulator, so that the network simulator continues to simulate. The present invention can control the subprocess to not continuously occupy resource, and first and second notification events can prevent a simulator timer from continuously running during the subprocess execution period, to cause an abnormal timing of a simulation result. |

Air treatment device and air conditioner indoor unit having the same
An air treatment device and an air conditioner indoor unit are provided. The air treatment device has an air outlet frame of a purification air duct. The air outlet frame has a ventilation hole and a cooperation hole. A water tank drawer is moveable on the air outlet frame and has two spaced-apart cooperation protrusions on a bottom wall thereof. A safety locking member of the air treatment device has a rotating shaft and a locking member. The rotating shaft is rotatable in the cooperation hole to switch the locking member between a locking position of the locking member and a movement-permitting position of the locking member. At the locking position, the locking member engages the cooperation protrusions to prevent the displacement of the cooperation protrusions. At the movement-permitting position, the locking member is located between the two cooperation protrusions to avoid engagement with the cooperation protrusions. |
