houdini-node-ops

houdini-node-ops is a skill for Claude Code, Codex from IvanYangYangXi/artclaw_bridge. It costs 61 tokens per session (3,404 once invoked), scanned A, original, MIT.

A Houdini guide for creating and connecting nodes and setting their parameters. Houdini is a 3D application that builds many models and effects as connected processing steps called nodes.

In plain words
What is it for?
Use it to create basic shapes, transformations, and other SOP nodes in Houdini, connect them into networks, set position, rotation, and scale, and choose the visible output.
Why use it?
It provides ready patterns for common node networks, reducing the need to remember Houdini’s Python commands for each operation. It also shows how to set display and render outputs and organize a graph.

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

houdini-node-ops 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 1mo 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.

Houdini 节点操作指南

节点创建、连接、参数设置和常见 SOP 工作流模板。

⚠️ 仅适用于 Houdini — 通过 run_python 执行,使用 hou 模块

📌 前置依赖: 执行任何修改操作前,请先阅读 houdini-operation-rules Skill


1. 创建常用 SOP 节点

基本几何体

import hou

with hou.undos.group("ArtClaw: 创建几何体"):
    geo = hou.node("/obj").createNode("geo", "my_geo")

    # 删除默认的 file 节点(新建 geo 会自带)
    for child in geo.children():
        child.destroy()

    # 创建基本几何体
    box = geo.createNode("box", "my_box")
    sphere = geo.createNode("sphere", "my_sphere")
    tube = geo.createNode("tube", "my_tube")
    torus = geo.createNode("torus", "my_torus")
    grid = geo.createNode("grid", "my_grid")
    circle = geo.createNode("circle", "my_circle")

    # 设置 box 为显示节点
    box.setDisplayFlag(True)
    box.setRenderFlag(True)

    geo.layoutChildren()

print("创建几何体完成")

Transform 节点

import hou

with hou.undos.group("ArtClaw: 创建 Transform"):
    geo = hou.node("/obj/geo1")
    box = geo.node("box1")

    xform = geo.createNode("xform", "move_up")
    xform.setInput(0, box)

    # 设置变换参数
    xform.parmTuple("t").set((0, 5, 0))    # 平移 Y=5
    xform.parmTuple("r").set((0, 45, 0))   # 旋转 Y=45°
    xform.parmTuple("s").set((2, 2, 2))    # 缩放 2x

    xform.setDisplayFlag(True)
    xform.setRenderFlag(True)
    geo.layoutChildren()

print("Transform 创建完成")

Merge 合并节点

import hou

with hou.undos.group("ArtClaw: 合并节点"):
    geo = hou.node("/obj/geo1")

    box = geo.createNode("box", "box1")
    sphere = geo.createNode("sphere", "sphere1")
    sphere.parmTuple("t").set((3, 0, 0))

    merge = geo.createNode("merge", "merge_all")
    merge.setInput(0, box)
    merge.setInput(1, sphere)

    merge.setDisplayFlag(True)
    merge.setRenderFlag(True)
    geo.layoutChildren()

print("Merge 完成")

Group 节点

import hou

with hou.undos.group("ArtClaw: 创建 Group"):
    geo = hou.node("/obj/geo1")
    box = geo.node("box1")

    # 按表达式分组
    group = geo.createNode("groupcreate", "top_faces")
    group.setInput(0, box)
    group.parm("groupname").set("top_group")
    group.parm("grouptype").set(0)          # 0=Points, 1=Prims, 2=Edges
    group.parm("grouptype").set(1)          # Primitives
    group.parm("groupbounding").set(1)      # 启用包围盒过滤
    group.parm("boundtype").set(0)          # Bounding Box
    group.parmTuple("size").set((10, 0.1, 10))
    group.parmTuple("t").set((0, 0.5, 0))   # 只选择顶部

    group.setDisplayFlag(True)
    group.setRenderFlag(True)
    geo.layoutChildren()

print("Group 创建完成")
