    摘要： Movie texture mapping is performed in which compressed textures CTEX-1 to CTEX-N are expanded to form expanded texture ETEX-1 to ETEX-N which are in turn mapped onto an object in a sequential manner. Movie texture mapping for the random replay is performed in which textures are mapped on the object OB1 in the order starting from ETEX-K, and also on the object OB2 in the order starting from ETEX-L. Movie texture mapping for the frame-decimation replay is performed in which mapping of the expanded texture ETEX-I is followed by mapping of the expanded texture ETEX (I+J) (when J≧2). The compressed movie texture data contains data used to designate storage locations of the compressed textures CTEX-1 to CTEX-N . The objects OB1 and OB2 can be arranged to overlap each other to represent an image having an increased area such as a flame image. Replay starting frames K and L may be randomly set, and the number of texture frames to be decimated (J−1) may be determined according to event occurrence or time passage.

    摘要翻译： 执行电影纹理映射，其中压缩纹理CTEX-1至CTEX-N被扩展以形成扩展纹理ETEX-1至ETEX-N，其依次以顺序映射到对象。 执行用于随机重放的电影纹理映射，其中纹理以从ETEX-K开始的顺序映射到对象OB1上，并且以从ETEX-L开始的顺序在对象OB2上映射。 执行帧抽取重放的电影纹理映射，其中扩展纹理ETEX-I的映射之后是扩展纹理ETEX（I + J）（当J> = 2时）的映射。 压缩的电影纹理数据包含用于指定压缩纹理CTEX-1到CTEX-N的存储位置的数据。 物体OB1和OB2可以被布置为彼此重叠以表示具有增加的面积的图像，例如火焰图像。 重放开始帧K和L可以是随机设置的，并且可以根据事件发生或时间通过来确定要抽取的纹理帧数（J-1）。
