Gaussian Splat\n\n在画布中查看 3D Gaussian Splatting 扫描，设定机位，渲染静帧与环绕视频，作为构图与空间参考连接到下游节点。本插件不是内置节点：它通过 [插件市场](https://opencinema.site/market/) 或“安装插件包”安装，同时也是 OpenCinema 插件链路能承载完整 3D 能力的验证。\n\n## 使用\n\n1. 添加节点后选择 `.ply`、`.splat`、`.ksplat` 或 `.spz` 文件，或连接一个 FILE 输入后点击“使用上游文件”。文件保存在工程的 `assets/<节点 ID>/` 下，节点记录格式、字节数、SHA-256 与 Gaussian 数量。\n2. 在节点内拖动旋转、滚轮缩放、右键平移。“保存机位”把当前视角写入节点并纳入画布历史；“自动取景”按扫描包围球重新取景。\n3. “渲染静帧”把 1280×720 PNG 写入 `image` 端口；“环绕视频”在后台逐帧渲染并用本机 FFmpeg 编码 4 秒 24 fps 的 H.264 MP4 写入 `video` 端口。`file` 端口原样输出扫描文件。\n\n渲染发生在本机浏览器的 WebGL 中，不上传文件、不调用生成模型。上限：100 MiB、2,000,000 个 Gaussian、环绕视频 600 帧。\n\n## Agent 操作\n\n通过 `getNodeTools` 发现函数：`getSplatInfo` 读状态，`setSplatSource` 选文件，`getCamera` / `setCamera` / `frameCamera` 管机位，`renderStill` 同步出图，`renderTurntable` 排队出视频并用 `getRenderStatus` / `cancelRender` 跟踪。随包发行的 `agent.md` 给出推荐顺序与边界。\n\n## 边界\n\n- 静帧与环绕视频是扫描的可视化参考，不是测量数据；`frameCamera` 的包围盒按 2%–98% 分位计算，会忽略远处漂浮点。\n- 更换扫描文件会清除旧机位与旧渲染输出；已写入的文件保留在工程里。\n- 需要宿主能力 `workspaceFiles`、`workspaceReadRange`、`nodeHistory`、`ffmpeg`、`worker`；环绕视频还需要在设置中就绪的 FFmpeg。\n\n## 第三方来源与许可\n\n-

`licenses/threeLicense.txt`。\n","agentGuide":"# Gaussian Splat · Agent 指南\n\n这个节点只做一件事：把一份 Gaussian Splatting 扫描变成可控机位的参考画面。\n\n## 推荐顺序\n\n1. `getSplatInfo`：读取来源、机位、渲染状态与输出端口。`source` 为 null 时先准备文件。\n2. `setSplatSource`：传入工作区内的 `.ply` / `.splat` / `.ksplat` / `.spz` 路径，或在已连接 FILE 输入时省略 `path`。返回 `splatCount`、`sha256` 与新的 `revision`。\n3. `frameCamera`：按包围球取景并保存机位；用 `azimuthDeg` / `elevationDeg` / `distanceScale` 调整构图。想要精确机位时直接 `setCamera`。\n4. `renderStill`：同步得到 PNG 路径并写入 `image` 端口。省略 `camera` 时使用已保存机位。\n5. `renderTurntable`：立即返回 `taskId`，用 `getRenderStatus` 轮询直到 `completed` 或 `failed`；`cancelRender` 可取消。完成后 `video` 端口才有产物。\n\n## 边界\n\n- 所有渲染在用户浏览器的 WebGL 中完成，不上传文件、不调用模型、不计费。\n- `running` 期间其他渲染与取景调用会以 `renderBusy` 拒绝；页面重载后旧任务显示为 `interrupted`，需要重新发起。\n- `expectedRevision` 是画布 documentRevision。环绕视频完成时按当时修订写入，长任务期间请避免并行改动该节点。\n- 输出是构图与空间参考，不是测量数据；更换来源会清除旧机位与旧输出。","resources":{}},"source":"const styles = [\"assets/ad9acbcea.css\"]; if (typeof document
