    • 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 morh 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计算morh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。
