Real game engines use this pattern (or its 3D cousin, the Octree) for broad-phase collision detection: the quadtree quickly identifies candidate pairs, and a more expensive narrow-phase check tests the actual geometry.
A notable resource on the topic of ordered dithering using arbitrary palettes is Joel Yliluoma’s Arbitrary-Palette Positional Dithering Algorithm. One key difference of Yliluoma’s approach is in the use of error metrics beyond the minimisation of . Yliluoma notes that the perceptual or psychovisual quality of the dither must be taken into account in addition to its mathematical accuracy. This is determined by use of some cost function which considers the relationship between a set of candidate colours. The number of candidates, the particular cost function, and the thoroughness of the selection process itself give rise to a number of possible implementations, each offering varying degrees of quality and time complexity.，详情可参考同城约会

他在日记中亲昵地叫儿子佳普斯、佳帕、安德留什卡，这些温柔的昵称，藏着一个父亲细腻的爱。在意大利拍摄《乡愁》期间，他偶遇一个站在路边等待搭便车的年轻人，这个画面瞬间击中了他，让他想起了留在苏联的、当时尚未成年的儿子。他在当天的日记中描绘：“他举着手，可是没有一个人停车。他有一头金发，看上去神情忧郁。我想起了佳帕。他也要长大，会变得更成熟，也更孤独。”
