基于 SOC 职业分类
Optimize Redshift rendering in SideFX Houdini — render settings, sampling, GI, lighting, shaders/textures, and CLI rendering. Use when tuning the Redshift ROP, choosing GI engines, reducing noise, dialing hyperrealistic vs. stylized looks, building RS Standard Material networks, processing textures, or rendering Redshift from the command line / farm. Triggers on Redshift, redshift, .rs, Redshift_ROP, redshiftCmdLine, rsMaterial, or GPU render optimization in Houdini.
Write Python (HOM) for SideFX Houdini — procedural modeling, animation, and render automation. Use when scripting the hou module, Python SOPs, parameter expressions, keyframe/animation rigs, ROP/Karma render farming, or translating sculpting and carving workflows into procedural code. Triggers on hou.node, hou.Geometry, Python SOP, hython, .hip automation, or any Houdini Python task.
SuperCollider sound design and music composition skill. Invoke this skill whenever the user asks for SuperCollider code, synthesis patches, sound design, algorithmic composition, patterns, UGen graphs, or anything related to SC/sclang. Generates idiomatic, musically expressive SuperCollider code with rich creative commentary. ALWAYS trigger for: SynthDef creation, Pbind/Pdef pattern writing, granular synthesis, FM synthesis, physical modeling, effects chains, JITLib live coding, DSP signal flow, creative sound exploration, and any request describing a sonic texture or musical idea needing SC implementation — even if the user doesn't say "SuperCollider" explicitly. Also trigger for questions like "how do I make X sound in SC" or "write me a patch that...".
Write GLSL shaders for TouchDesigner's GLSL TOP, GLSL MAT, and GLSL COMP operators. Use when creating pixel shaders, vertex shaders, compute shaders, visual effects, image processing, generative art, GPU computations, or working with .glsl/.frag files for TouchDesigner.
Write GLSL vertex shaders for TouchDesigner's GLSL MAT operator. Use whenever creating 3D materials, vertex displacement, geometry deformation, mesh animation, instancing effects, custom surface normals, or any shader that needs to manipulate vertex data in 3D space. Also covers the complete vertex + pixel shader pair for GLSL MAT. Trigger when the user mentions GLSL MAT, vertex shader, vertex displacement, mesh deformation, instancing in TouchDesigner, 3D material writing, surface normals in GLSL, or wants to create a custom material for a SOP/geometry node.
Write GLSL compute shaders for TouchDesigner's POP (Point Operator) family — GLSL POP, GLSL Advanced POP, GLSL Copy POP, and GLSL Select POP. Use this skill whenever the user wants to create particle systems, point cloud manipulation, geometry processing, GPU-driven point simulations, instancing with GLSL, or any compute-shader work inside TouchDesigner's POP context. Trigger on mentions of GLSL POP, particle shader, point operator, compute shader for particles, point cloud GLSL, POP attributes, SSBO particle data, GLSL Copy POP, GLSL Advanced POP, or any request to manipulate points/vertices/primitives with GLSL in TouchDesigner.

Write high-performance VEX code for geometry manipulation, simulation, and shading in Houdini.
Basic Point Wrangle pattern:
// Access and modify point position
@P += @N * 0.1;
// Set color based on position
@Cd = normalize(@P);
@ to access attributes (@P, @Cd, @N)v@, i@, s@, f@)// Automatic type detection for known attributes
@P // vector - position
@N // vector - normal
@Cd // vector - color
@pscale // float - point scale
// Manual type specification for custom attributes
v@velocity // vector
i@id // integer
s@name // string
f@custom // float
See examples/PATTERNS.md for ready-to-use code:
Point Wrangle: Runs per-point (most common)
@ptnum, @numptPrimitive Wrangle: Runs per-primitive
@primnum, @numprimDetail Wrangle: Runs once for entire geometry
Vertex Wrangle: Runs per-vertex
@vtxnum, @numvtx// Geometry queries
int nearpoints(geometry; vector pos; float radius)
int neighbours(geometry; int ptnum)
vector point(geometry; string attr; int ptnum)
// Attribute creation
addpoint(geometry; vector pos)
removepoint(geometry; int ptnum)
setpointattrib(geometry; string name; int ptnum; value)
// Noise
float noise(vector pos)
vector curlnoise(vector pos)
vnoise(vector pos)
// Math
normalize(vector)
distance(vector, vector)
dot(vector, vector)
cross(vector, vector)
