科技感3D路径叙事视觉海报

Design a 3:4 vertical "Path Narrative 3D Scene" visual poster for [Subject / Product / Workflow], 3D Journey Mapping. The overall background uses a gradient from deep navy blue to pure black. The center of the image is a three-dimensional path entering from the bottom left and spiraling upwards into the distance, forming a clear S-shaped visual movement. The path has real spatial thickness, soft chamfers, and precise engineering structures. Four key nodes are sequentially set along the path: [Start], [Transformation], [Processing], and [Outcome]. Each node uses miniature buildings, equipment, figures, or abstract installations to represent the corresponding stage. The core product or final outcome is located at the end of the path, has the largest size, and is illuminated by a cold white spotlight, becoming the focus of the entire image. The overall style uses isometric perspective and a miniature sandbox texture, with materials combining matte metal, frosted glass, and low-reflection plastic. The main color palette consists of deep blue, graphite black, and cold white, with only a small amount of electric cyan used to mark the path direction. The title uses a bold sans-serif font, occupying about 20% of the upper area of the image. Node information uses small numbers, coordinates, arrows, and extremely short labels. The overall effect is like a combination of a future transportation system, a tech brand official website, and cinematic 3D information visuals. Avoid ordinary flowcharts, flat arrows, dense text, cartoon toy feels, neon cities, and meaningless mechanical parts.

为【主题 / 产品 / 工作流程】设计一张 3:4 竖版“路径叙事式3D场景”视觉海报，3D Journey Mapping。
整体采用深海军蓝到纯黑的渐变背景。
画面中心是一条从左下方进入、向远处盘旋上升的立体路径，形成清晰的 S 形视觉动线。路径具有真实空间厚度、柔和倒角和精密工程结构。
沿路径依次设置 4 个关键节点：
【起点】、【转化】、【处理】、【成果】
每个节点用微缩建筑、设备、人物或抽象装置来表达对应阶段。
核心产品或最终成果位于路径终点，尺寸最大，并被冷白色聚光照亮，成为全画面焦点。
整体采用等距透视与微缩沙盘质感，材质结合哑光金属、磨砂玻璃和低反射塑料。
主色调为深蓝、石墨黑和冷白色，仅使用少量电光青标记路径方向。
标题使用粗体无衬线字体，占画面上方约 20% 区域。
节点信息采用小型编号、坐标、箭头和极短标签。
整体效果像未来交通系统、科技品牌官网与电影级3D信息视觉的结合。
避免普通流程图、扁平箭头、密集文字、卡通玩具感、霓虹城市和无意义机械零件。
