    • Disclosed herein are a method for implementing switching between layer-2 multicast route tracing and layer-3 multicast route tracing, and a method, a system, a router and an apparatus for differentiating between a layer-2 property and a layer-3 property. One of the methods includes: The query apparatus judges whether to perform layer-2 multicast route tracing, and adds an IP option of layer-2 multicast route tracing into the IGMP Tracert Query packet if layer-2 multicast route tracing needs to be performed. The last-hop router receives the IGMP Tracert Query packet, judges whether the packet carries the IP option of layer-2 multicast route tracing, and transmits the IGMP Tracert Query packet to a downstream layer-2 node transparently if the packet carries the IP option, or initiates layer-3 multicast route tracing if the packet carries no such IP option. The method, system, and router disclosed herein can implement switching between layer-2 multicast route tracing and layer-3 multicast route tracing, and enable the query apparatus to identify the layer property of each IGMP Tracert Response data block.
    • 这里公开了实现第2层组播路由跟踪和第3层组播路由跟踪之间的切换的方法,以及用于区分第2层属性和第3层属性的方法,系统,路由器和装置。 其中一种方法包括:如果需要执行二层组播路由跟踪,则查询设备判断是否进行二层组播路由跟踪,并将二层组播路由跟踪的IP选项添加到IGMP Tracert Query报文中。 最后一跳路由器收到IGMP Tracert Query报文,判断报文携带第二层组播路由跟踪的IP选项,如果报文携带IP选项,则将IGMP Tracert Query报文透传到下游二层节点 或者如果分组不携带这样的IP选项,则发起第3层组播路由跟踪。 本文公开的方法,系统和路由器可以实现第2层组播路由跟踪和第3层组播路由跟踪之间的切换,并使查询设备能够识别每个IGMP Tracert响应数据块的层属性。

    • A fast, texture morphing algorithm for real-time computer simulation and video games dynamically generates objects “on the fly” by simplifying and reducing the computational load required for a texture morphing/blending process. Incremental interpolation techniques compute a morph parameter based on previous value and morph change rate. Precomputed initial and incremental morph parameter values for each texel component are applied during real-time morphing procedures using integer arithmetic. Approximation errors are reduced by incrementing/decrementing by an extra integer value when the number of morph iterations is a multiple of a frame counter. The frame counter avoids over-runs, and the morphing procedure is “snapped” the texel value to the precise texture target value to prevent under-runs and corresponding artifacts. Interlacing (applying interpolation to a subset of the texels each frame) significantly reduces computational load without introducing significant image artifacts. The morph texture buffer data structure is initially decomposed off-line to reduce the number of real-time calculations required to manipulate texel component data.
    • 用于实时计算机模拟和视频游戏的快速,纹理变形算法通过简化和减少纹理变形/混合过程所需的计算负荷来“动态地”生成对象。 增量插值技术基于先前的值和变形率来计算变形参数。 使用整数算法在实时变形过程中应用每个纹素分量的预计算初始和渐变变形参数值。 当变形迭代次数是帧计数器的倍数时,通过递增/递减额外的整数值来减少近似误差。 帧计数器避免过度运行,并且变形过程将纹素值“拍”到精确的纹理目标值,以防止运行不足和相应的伪像。 隔行扫描(将插值应用于每个帧的纹素集的子集)可显着降低计算负荷,而不引入显着的图像伪像。 变形纹理缓冲器数据结构最初是离线分解的,以减少操纵纹理分量数据所需的实时计算的数量。

    • Compressing and decompressing techniques for transformation matrices 3D computer graphics systems use to animate objects achieve high compression ratios by taking advantage of common characteristics of homogenous 3D transformation matrices. The techniques use a bitmap to encode information on locations of ones and zeros of the matrix—bypassing the penchant of compilers to represent such information as high-precision numbers. Since most video game processors and display hardware are constrained by their resolutions and since an original transformation matrix often stores data that is more accurate than necessary, the techniques convert some real numbers in the matrix (e.g., those within the range of −1 and 1) into integers by scaling them by a constant. The resulting compressed matrices occupy much less storage space than their non-compressed counterparts, and can be efficiently decompressed in real time for use in interactive real time 3D animations.
    • 用于变换矩阵的压缩和解压缩技术3D计算机图形系统用于通过利用均匀3D变换矩阵的共同特征来动画对象来实现高压缩比。 这些技术使用位图来对基于矩阵的零和零的位置的信息进行编码,从而绕过编译器的倾向,以表示诸如高精度数字的信息。 由于大多数视频游戏处理器和显示硬件都受到其分辨率的约束,并且由于原始的变换矩阵通常存储比所需更准确的数据,所以这些技术将矩阵中的某些实数(例如,-1和1范围内的那些数字) )通过将它们缩放为常数来整数。 所得到的压缩矩阵占据比非压缩对等体少得多的存储空间,并且可以实时有效地解压缩以用于交互式实时3D动画。
