2x2 grid, 16:9, AI picks topics: I(0) = blank matte background. I(1) = final isometric miniature of $ DESTINATION, its landmass cut as silhouette $ SHAPE and floating as a diorama partitioned into four wedges — $ STATE_1, $ STATE_2, $ STATE_3, $ STATE_4 — with ONE continuous $ PATH flowing unbroken through all four. ∂I/∂t = Δ(I, $ DESTINATION, $ SHAPE) under a piecewise state field S(θ) that rotates through the four quadrants. Constraints: isometric projection, base-shape adherence, center-outward build order, seamless path continuity across seams, four distinct palettes/weathers meeting cleanly at the center, cross-section side walls, soft global illumination. Integration: t=0.0–0.15: faint isometric base outline in silhouette $ SHAPE, quadrant seams and a light guide grid appear. t=0.15–0.4: the central hub landmark of $ DESTINATION rises first where all four wedges meet; the $ PATH's spine blocks in. t=0.4–0.7: each quadrant fills outward in its own state — foliage, weather, lighting and tiny figures shifting per wedge — while the $ PATH threads a little traveler/vehicle through the transitions. t=0.7–0.9: edges resolve into a clean cross-section revealing strata; each wedge's outer props finalize the silhouette. t=0.9–1.0: soft shadows, small labels for each state and stop appear, global illumination settles, final polish. Output I(1) as an 8K isometric four-state journey diorama masterwork.

2x2 网格，16:9，AI 选题：I(0) = 空白哑光背景。I(1) = $ DESTINATION（目的地）的最终等距微缩模型，其陆地按 $ SHAPE（轮廓形状）裁切并漂浮成一个分为四个楔形区块的立体模型 —— $ STATE_1、$ STATE_2、$ STATE_3、$ STATE_4 —— 其中有一条连续的 $ PATH（路径）不断裂地贯穿全部四个区块。∂I/∂t = Δ(I, $ DESTINATION, $ SHAPE)，在分段状态场 S(θ) 之下，状态场在四个象限之间轮转。约束条件：等距投影、严格贴合基础形状、由中心向外的构建顺序、跨接缝的无缝路径连续性、四种不同的色调/天气在中心整齐交汇、横截面侧壁、柔和全局光照。分阶段过程：t=0.0–0.15：出现淡淡的等距基础轮廓，呈 $ SHAPE 剪影，呈现象限接缝与轻量引导网格。t=0.15–0.4：$ DESTINATION 的中心枢纽地标率先在四个楔形交汇处升起；$ PATH 的主干定型。t=0.4–0.7：每个象限以各自状态向外延展 —— 植被、天气、光照与微小人物随楔形而变 —— 同时 $ PATH 让一位小旅人/小车穿行于各状态之间。t=0.7–0.9：边缘收束为整洁的横截面，显露地层；各楔形外侧道具定型整体剪影。t=0.9–1.0：柔和阴影出现，为每个状态与停靠点加上小标签，全局光照定型，最终润色。输出 I(1) 为一张 8K 等距四态旅程立体模型杰作。
