PBRRender 🎨

PBR（基于物理）3D 模型预览插件 for DeepSeek Harness A Physically-Based Rendering 3D model preview plugin for DeepSeek Harness

渲染 GLB/GLTF 游戏美术资源，带贴图纹理、环境光照、轨道控制、材质通道检查，直接在模型回答里交互预览。 Render GLB/GLTF game-art assets inside chat with PBR textures, environment lighting, orbit controls, and material-channel inspection — fully interactive.

🔌 生态 / Ecosystem：仓库已挂 #dsh · #dsh-plugin · #pbr · #gltf topic，欢迎社区收录。 The repo carries the #dsh · #dsh-plugin · #pbr · #gltf topics — community welcome.

🖼️ 效果展示 / Showcase

同一模型的材质通道检查（点击模式栏实时切换，以下为各模式渲染截图）。 Material-channel inspection of the same model (switch live via the mode bar; screenshots of each mode below).

标量通道（粗糙度/金属度/AO）按 PBR 规范以灰度显示——正是游戏引擎（Unity/UE）读取的原始贴图通道数据。 Scalar channels (roughness/metallic/AO) are shown in grayscale per PBR convention — the raw texture-channel data game engines (Unity/UE) actually read.

✨ 特性 / Features

PBR 渲染 / PBR Rendering

• 金属/粗糙度/法线/自发光/AO 贴图自动加载（GLB 内嵌或 GLTF 兄弟文件）
• Metalness / roughness / normal / emissive / AO maps load automatically (embedded in GLB or as GLTF sibling files)

材质通道检查 / Material-Channel Inspection

• viewer 顶部模式栏一键切换 —— PBR / 基础色 / 法线 / 粗糙度 / 金属度 / AO / 自发光 / 线框
• One-click mode bar at the top of the viewer — PBR / base color / normal / roughness / metallic / AO / emissive / wireframe

真实 HDR 环境光 / Real HDR Environment Lighting

• 内置 5 种 CC0 HDR 环境图（Poly Haven 1K）—— studio 棚拍 / sunset 黄昏 / outdoor 户外 / sunrise 日出 / night 夜晚，env 字段切换，envBackground 可显示为背景；未指定时回退程序化 RoomEnvironment。viewer 顶部有"环境"切换栏，预览时可直接点击换环境
• 5 built-in CC0 HDR environments (Poly Haven 1K) — studio / sunset / outdoor / sunrise / night, switched via the env field, or shown as the background with envBackground; falls back to a procedural RoomEnvironment when unset. An on-viewer "environment" bar lets you swap environments live

交互 / Interaction

• 拖拽旋转、滚轮缩放、自动旋转、曝光调节、一键全屏（右上角 ⛶ 按钮，Fullscreen API + 移动端覆盖层降级）
• Orbit by dragging, zoom with the wheel, auto-rotate, exposure control, and one-click fullscreen (⛶ button, Fullscreen API with mobile overlay fallback)

主动触发 / Active Triggering

• 模型发现 3D 模型文件（API 生成/下载/工作区出现）时自动调用 pbr_render 工具并渲染预览，无需用户提示
• Automatically calls the pbr_render tool and renders a preview when a 3D model file appears (API-generated / downloaded / dropped into the workspace) — no user prompt needed

安全 / Security

• 文件服务工作区限定 + 扩展名白名单 + 512 MiB 上限
• Workspace-scoped file serving + extension whitelist + 512 MiB ceiling

安装 / Installation

# GitHub 仓库安装 / Install from the GitHub repo
dsh plugin --profile web add github:dhb861832993-star/pbr-render

# 或本地开发 / Or for local development
pnpm install
node scripts/build.mjs
dsh plugin --profile web add link:/path/to/pbr-render

重启 dsh web，新会话生效。 Restart dsh web; takes effect on a new session.

使用 / Usage

插件自动注入系统提示教学。模型在合适场景主动调用 pbr_render 工具验证路径，然后输出 pbr3d 围栏： The plugin injects a system-prompt guide automatically. The model calls the pbr_render tool to validate the path, then emits a pbr3d fence:

```pbr3d
{"model":"E:/generated/robot.glb","autoRotate":true,"label":"API 生成的机器人 / API-generated robot"}
```

围栏规格 / Fence Spec

材质通道模式 / Material-Channel Modes

架构 / Architecture

• lib/index.js — host 半边：pbr_render 工具 + 文件服务路由 + 系统提示段 / host half: the pbr_render tool + file-service route + system-prompt section
• lib/client.js — 浏览器半边：DOM 观察 pbr3d 围栏 → 按需加载 three 资产 → PBR 渲染 / browser half: DOM-watches pbr3d fences → lazy-loads the three assets → renders PBR
• src/three-entry.js + scripts/build.mjs — three.js 引擎打包（esbuild）/ three.js engine bundling via esbuild
• lib/assets/env/*.hdr — 内置 HDR 环境图（CC0, Poly Haven 1K，RGBE 格式）/ built-in HDR environments (CC0, Poly Haven 1K, RGBE)
• test-model.glb / test-tex.glb — 演示模型（单色 + 全套贴图）/ demo models (solid-color + full texture set)

安全 / Security

• 文件服务仅暴露工作区内的路径（防目录穿越）/ the file service only exposes paths inside the workspace (traversal-safe)
• 仅放行模型/纹理扩展名（.glb/.gltf/.bin/.ktx2/.hdr/.png/.jpg/.webp/.avif）/ only model/texture extensions are allowed
• 文件上限 512 MiB / 512 MiB file ceiling
