    • A method and device for performing and processing user-defined clipping in object space to reduce the number of computations needed for the clipping operation. The method and device also combine the modelview transformation of the vertex coordinates with projection transform. The user-defined clipping in object space provides a higher performance and less power consumption by avoiding generation of eye coordinates if there is no lighting. The device includes a driver for the user-defined clipping in the object space to perform dual mode user-defined clipping in object space when a lighting function is disabled and in eye space when the lighting function is enabled.
    • 一种用于在对象空间中执行和处理用户定义的限幅以减少剪切操作所需的计算次数的方法和装置。 该方法和装置还将顶点坐标的modelview变换与投影变换相结合。 对象空间中的用户定义的剪辑通过避免在没有照明的情况下产生眼睛坐标来提供更高的性能和更低的功耗。 该设备包括用于在对象空间中的用户定义的剪切的驱动器,以在禁用照明功能时在对象空间中执行双模式用户定义的剪辑,并且在启用照明功能时在眼睛空间中执行双模式用户定义的剪辑。

    • A three dimensional (3D) mixed reality system combines a real 3D image or video, captured by a 3D camera for example, with a virtual 3D image rendered by a computer or other machine to render a 3D mixed-reality image or video. A 3D camera can acquire two separate images (a left and a right) of a common scene, and superimpose the two separate images to create a real image with a 3D depth effect. The 3D mixed-reality system can determine a distance to a zero disparity plane for the real 3D image, determine one or more parameters for a projection matrix based on the distance to the zero disparity plane, render a virtual 3D object based on the projection matrix, combine the real image and the virtual 3D object to generate a mixed-reality 3D image.
    • 三维(3D)混合现实系统将由3D摄像机捕获的真实3D图像或视频与由计算机或其他机器呈现的虚拟3D图像组合以渲染3D混合现实图像或视频。 3D摄像机可以获取公共场景的两个单独的图像(左和右),并且叠加两个分离的图像以创建具有3D深度效果的实际图像。 3D混合现实系统可以确定实际3D图像到零视差平面的距离,基于到零视差平面的距离确定用于投影矩阵的一个或多个参数,基于投影矩阵渲染虚拟3D对象 ,组合真实图像和虚拟3D对象以产生混合现实的3D图像。

    • This disclosure describes a multi-stage tessellation technique for tessellating a curve during graphics rendering. In particular, a first tessellation stage tessellates the curve into a first set of line segments that each represents a portion of the curve. A second tessellation stage further tessellates the portion of the curve represented by each of the line segments of the first set into additional line segments that more finely represent the shape of the curve. In this manner, each portion of the curve that was represented by only one line segment after the first tessellation stage is represented by more than one line segment after the second tessellation stage. In some instances, more than two tessellation stages may be performed to tessellate the curve.
    • 本公开描述了用于在图形渲染期间细分曲线的多阶段镶嵌技术。 特别地,第一细分阶段将曲线细分为第一组线段,每组线段表示曲线的一部分。 第二细分阶段进一步将由第一组的每个线段表示的曲线的部分细分为更精细地表示曲线形状的附加线段。 以这种方式,在第一细分阶段之后仅由一个线段表示的曲线的每个部分在第二细分阶段之后被多于一个线段表示。 在一些情况下,可以执行多于两个的细分阶段来细分曲线。
