Abstract: The present disclosure discloses an optical module including: a circuit board; a housing assembly divided by a separation board into a first portion and a second portion that are stacked one above the other, wherein a light-emitting cavity is formed in the second portion, and a partition wall is provided in the first portion to separate the first portion into a light-receiving cavity and a slot, and is provided with a plurality of light-passing holes via which the light-receiving cavity is in communication with the slot; an optical fiber adapter disposed in the housing assembly and in communication with the light-receiving cavity; a light-emitting assembly arranged in the light emitting cavity and electrically connected to the circuit board, wherein heat generated by the light-emitting assembly is conducted to a surface of the housing assembly via the partition wall; and a light-receiving assembly.

Abstract: Aspects of the disclosure provide methods and apparatuses for displaying a gesture in a virtual reality (VR) environment. In some examples, an apparatus for displaying the gesture in the virtual reality (VR) environment includes processing circuitry. The processing circuitry displays a first gesture object corresponding to a state of a virtual hand when the virtual hand does not hold a virtual article. The processing circuitry displays a second gesture object when a ray of the first gesture object intersects the virtual article. The second gesture object indicates that the virtual article is in front of the virtual hand. The ray extends from the virtual hand. The processing circuitry displays a third gesture object in response to a selection instruction. The third gesture object corresponds to a state of the virtual hand when the virtual hand holds the virtual article.

Abstract: A curved surface model generation method and apparatus in a three-dimensional (3D) scenario are provided. The method includes obtaining a curved surface parameter inputted for a to-be-generated curved surface model; and obtaining two-dimensional coordinates of a plurality of sampling points. A first dimensional direction of each sampling point is a direction of a chord corresponding to an arc at a radial cross section of the curved surface model. A second dimensional direction is a curved-surface width direction of the curved surface model. The method also includes determining, for each sampling point, a coordinate value of the sampling point in a third dimensional direction based on the curved surface parameter, the third dimensional direction being perpendicular to the first dimensional direction and the second dimensional direction; and generating the curved surface model based on coordinate values of each sampling point in the first, second, and third dimensional directions.
