three-blazor-dev

three-blazor-dev is a skill for Claude Code, Codex from grasscaograss/AwesomeWeldoneSkills. It costs 39 tokens per session (1,324 once invoked), scanned A, original, Apache-2.0.

A development guide for building interactive 3D scenes with three-blazor, a Blazor wrapper around the Three.js 3D library designed for industrial simulation and welding visualisation.

In plain words
What is it for?
Use it to initialise 3D scenes, load STL and URDF models, draw geometry, play animations, and add controls in Blazor or TypeScript.
Why use it?
It provides project-specific instructions for setting up scenes and using the library’s model, geometry, animation, and interaction features.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

three-blazor-dev scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 7d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Three-Blazor 3D 场景开发指南

核心概念

three-blazor (@robim/three-blazor) 是基于 Three.js 的高级封装库,专为工业仿真和焊接可视化设计。

文档参考

详细 API 文档请参考: docs/libraries/three-blazor.md

项目中的使用入口

  • TypeScript 入口: src/Weldone/Assets/ts/three-blazor.ts
  • Blazor 组件: src/Weldone/Components/ThreeDisplay.razor

初始化 3D 场景

Blazor 组件方式

<ThreeDisplay @ref="_threeDisplay"
              Id="my-scene"
              ShowAxes="true"
              ShowGrid="true" />
@code {
    private ThreeDisplay? _threeDisplay;

    protected override async Task OnAfterRenderAsync(bool firstRender)
    {
        if (firstRender && _threeDisplay?.Core != null)
        {
            // 使用 Core 进行 3D 操作
            await _threeDisplay.Core.LoadSTLAsync("/models/part.stl", "part", true);
        }
    }
}

TypeScript 方式

import { ThreeCore } from '@robim/three-blazor';

const core = new ThreeCore(
    'container-id',  // DOM 容器 ID
    true,            // 显示坐标轴
    true,            // 显示网格
    true,            // 启用后处理
    false,           // CSS2D 渲染器
    false            // CSS3D 渲染器
);

常用操作

加载模型

// STL 文件
await core.LoadSTLAsync('/models/workpiece.stl', 'workpiece-key', true);

// URDF 机器人
await core.LoadURDFAsync('/robots/robot.urdf');

// 从 Base64
await core.LoadSTLFromBytesAsync(base64Data, 'model-key', true);

几何图形绘制

// 直线
core.AddLine('line-1', 'group', [0,0,0], [100,0,0], 0xff0000, 2);

// 圆弧 (起点, 中点, 终点)
core.AddArc('arc-1', 'group', [0,0,0], [50,50,0], [100,0,0], 0x00ff00, 2);

// 圆形
core.AddCircle('circle-1', 'group', 50, [0,0,0], [0,0,1], 0x0000ff, 2);

圆弧曲线计算

import { ArcCurve3 } from '@robim/three-blazor';
import * as THREE from 'three';

// 通过三点创建圆弧曲线
const arc = ArcCurve3.createFromThreePoint(
    new THREE.Vector3(0, 0, 0),
    new THREE.Vector3(50, 50, 0),
    new THREE.Vector3(100, 0, 0)
);

// 获取插值点
const points = arc.getPoints(30);

相机控制

// 适配到对象
await core.FitCameraToObject('model-key', 1.5);

// 适配到场景
await core.FitCameraToScene(1.2);

// 切换相机类型
core.SwitchToPerspectiveCamera();
core.SwitchToOrthographicCamera();

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

three-blazor-dev is a skill published in the GitHub repository grasscaograss/AwesomeWeldoneSkills (2 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 39 tokens to every session and 1,324 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
