开场应先让人看见落差，不必急着解释。在这个虚构体验里，透明滑梯从云层上方出发，经过一个宽阔左弯，接近青绿色泳池。镜头始终跟随乘坐者，不切到外部奇观视角。
本教程准备五张参考图，规划在 Arcloop 发起一次十秒请求。它不是已完成的游乐设施模拟，也不是真实景点影像。图片是在 Arcloop 之外生成的写实概念参考。
逐步制作不可能的第一视角体验
第 1 步：设计一条观众能看懂的路线
只用起点、转弯和终点。开场展示高度并露出泳池，中段保持同样的滑道侧壁与蓝色支撑肋，结尾从水面高度接近直接相连的泳池，不从空中掉进另一片风景。
| 时间 | 镜头与路线 |
|---|---|
| 0 至 2 秒 | 从看得见的落差处开始前进 |
| 2 至 8 秒 | 沿一个宽阔的左倾弯滑行 |
| 8 至 10 秒 | 不离开滑槽，接近泳池 |
这些是目标节奏，不保证精确时刻或物理模拟轨迹。简单路线比多环、跳跃的迷宫更容易检查错误。
第 2 步：准备五张分工不同的参考图
参考图 1. 乘坐入口视角：展示云端高度、透明滑槽与可见终点
ride-entry.png
参考图 2. 外部路线设计：单独核对起点、左弯与泳池连接
route-design.png
参考图 3. 乘坐弯道视角：固定向左转弯、双脚和蓝色支撑肋
ride-bend.png
参考图 4. 乘坐出口视角：定义滑槽与泳池水面的直接连接
ride-exit.png
参考图 5. 滑梯材质细节：检查透明侧壁、接缝和水膜
slide-material.png
入口、弯道和出口定义乘坐者的视角。外部路线图帮助检查三者能否属于同一条路径。材质细节用于检查透明侧壁厚度、接缝和水。外部设计视图和材质特写都不应加入实际乘坐视角的生成请求。
这个区别很重要。参考图丰富，前提是各自用途明确。不解释就上传所有角度，模型可能在中途切到滑梯外面。

不附参考图，生成新图片。
Use case: photorealistic-natural. Asset type: original video production reference. One coherent photographic frame, landscape 16:9 unless a different ratio is specified. Real material texture, believable lighting and scale. No text, captions, logos, watermark, UI, illustration or cartoon. A fictional photoreal first-person action-camera still at the entrance of one transparent smooth U-shaped water slide suspended above a sunlit cloud layer. The viewer sees two bare adult feet at bottom edge, a thin water flow moving away, rounded transparent side walls with dark blue support ribs, and a distant turquoise landing pool visible through a gap in clouds below. The slide drops forward then curves gently left. Readable height and route, not an exterior drone view, no skyscraper clutter, text, logos, straps or other people.

Use case: photorealistic-natural. Asset type: original video production reference. One coherent photographic frame, landscape 16:9 unless a different ratio is specified. Real material texture, believable lighting and scale. No text, captions, logos, watermark, UI, illustration or cartoon. Use image 1 for transparent slide material, dark blue support ribs, clouds and distant pool. New wide exterior photographic route-design reference, showing only ONE continuous slide path from a small entry platform above the clouds through one broad banked left curve to a single turquoise pool lower down on a stable mountain terrace. The slide has no branches, loops, jumps or broken sections; supports grounded in terrace rock. No riders or people. This is a route design reference, never a request to switch a POV video to drone footage.

Use case: photorealistic-natural. Asset type: original video production reference. One coherent photographic frame, landscape 16:9 unless a different ratio is specified. Real material texture, believable lighting and scale. No text, captions, logos, watermark, UI, illustration or cartoon. Image 1 defines the adult feet, first-person camera and slide material; image 2 defines the single left-curving path to the pool. New photorealistic first-person frame in the middle of that banked curve, feet remain at lower edge, blue ribs and transparent walls continuous, turquoise destination pool still visible ahead, limited spray only at image corners. Horizon tilts modestly with bank, no inverted view, hands, external camera, jump or cut.

Real material texture, believable lighting and scale. No text, captions, logos, watermark, UI, illustration or cartoon. Use image 1 for first-person adult feet, clear slide and blue ribs; image 2 for the mountain terrace pool. New first-person photographic approach frame at the end of the same slide, its chute connects directly into the turquoise pool at water level, continuous low sidewalls and visible pool edge. Pool fills most of forward view, white cloud bank and distant mountains beyond. No airborne fall, broken chute, collision, other swimmers, gore or external viewpoint. Fictional ride concept only.

Real material texture, believable lighting and scale. No text, captions, logos, watermark, UI, illustration or cartoon. Use image 1 for the same slide. Macro photographic reference of a rounded clear polymer wall section joined to one dark blue structural rib, tiny realistic water beads and a thin water film, sunlight refracting softly through the material, cloud layer far below out of focus. Make the wall transparent but visibly solid with clear thickness, no glass shards, broken seam, body part, writing, embossed brand or logo. This is a material reference, not the camera framing for the whole ride.
对比三张乘坐图中的双脚与蓝色支撑肋。转弯方向要一致，出口要接入泳池，不能停在泳池上方。
第 3 步：向 Arcloop 请求一段连续第一视角视频
打开 Arcloop 项目。本次只附 ride-entry.png、ride-bend.png 和 ride-exit.png。选择 Vidu Q4 Preview、参考图生成视频、十秒、720p、16:9。需要测试水声与风声时，开启生成音频。
把方括号文件名替换成实际素材引用。每张图引导一部分路线，不是精确指定第一帧、中间帧或最后一帧。Q4 指南 解释了参考模式及其限制。
完整视频提示词
请求 1: 连续第一视角滑行
Vidu Q4 Preview, 参考图生成视频, 10 秒, 720p, 16:9. 只附以下素材: ride-entry.png, ride-bend.png, ride-exit.png.
Create one continuous ten second photorealistic first-person fictional waterslide ride, 16:9. [ride-entry.png] guides the opening height, the same two adult bare feet at the lower edge, transparent rounded U-shaped slide walls and dark-blue support ribs above clouds. [ride-bend.png] guides ONE broad left-banked turn, not a cut to a separate location. [ride-exit.png] guides the final destination: the same chute connected directly into one turquoise pool on a mountain terrace. Start at the already-visible drop, pool glimpsed below. First two seconds begin moving forward with a thin water film. Seconds two to eight follow the continuous left curve, modest horizon bank, clouds passing outside, a little spray at corners but the route remains visible. Seconds eight to ten approach the connected pool at water level and slow the apparent motion slightly. Remain at the rider's eye position throughout. Feet retain size and position relative to camera. No drone view, reverse angle, cuts, loop, teleport, branches, inverted turn, jump, broken chute, airborne fall, collision, other person, text, logo, cartoon or music. Soft rush of water and wind, no scream or dialogue. Duration beats are targets; this is a fictional impossible ride, not footage of a real attraction.
第 4 步：确认生成前检查任务摘要
核对模型、三张指定图片、时长、比例、分辨率、音频设置和积分估算。不要把这个任务称为首帧加尾帧生成；三张图不是这样使用的。
先生成简单路线。外部设计与材质图留在旁边做检查，如果输入已经清楚，就不必把它们再加入任务。
第 5 步：检查视角、连续性与终点接近方式
正常速度看，是否始终坐在同一位置？再暂停看入口、弯道和出口。双脚大小要稳定，蓝色支撑肋要连接滑槽，泳池应沿看得懂的方向逐渐靠近。
突然出现无人机镜头、新岔路、断裂侧壁或瞬移终点，都不合格。路线不清时，先降低速度、减缓弯道，再增加更炫的动作。水花不能遮满画面，把路径藏起来。
单独检查声音，使用克制的流水与风声，不要全程尖叫。在剪辑软件里只做有助于理解的裁剪；实际有切镜，就不要称为连续镜头。成片标明是虚构 AI 游乐体验。
常见问题
一次连续请求就能保证一个长镜头吗？
不能。提示词提出要求，结果仍需检查。隐藏切镜或变成外部角度，在本练习中仍算失败。
不上传外部路线图，为什么还要准备？
它是规划和检查素材，让你比较入口、转弯与泳池，不让模型模仿它的机位。不是每张有用的制作参考都适合加入每次生成。
可以做成竖屏吗？
参考模式提供竖屏输出，但应重新构图三张乘坐图，不要默认横图裁切后仍清楚。落差、双脚和终点要同时看得懂。
这是真实设施设计或安全模拟吗？
不是。这是不可能的视觉概念，不是工程建议或真实景点存在的证明。查看任务估算并预留重试，不保证首条可用，也没有固定价格。
