three.js textures: Texture, DataTexture, CubeTexture, CompressedTexture variants, DepthTexture, VideoTexture, CanvasTexture, 3D/array textures, Source; sampling parameters, mipmaps, anisotropy, wrap/mag/min filters; PMREMGenerator in Extras for environment map prefiltering. Use when configuring GPU texture objects and PMREM; for Draco/KTX2 transcoder file paths use threejs-loaders; for material map slots use threejs-materials; for output color pipeline use threejs-renderers.

    website-to-video

    Capture a general website/URL and turn it into a video OF the site — tour, showcase, or social clip built from captured screenshots and the site's own brand assets. Use for portfolio / blog / docs / landing-page showcases. Not a product launch or promo, even from a URL (/product-launch-video). Unclear → /hyperframes.

    visual-style

    Build a persistent visual brand identity for image generation. Defines how the brand looks visually — aesthetic, lighting, composition, mood — and writes it to brand/creative-kit.md so /image-gen and other creative skills produce consistent on-brand visuals. Three modes: Extract (from website/URL), Build (interview), Reference (mood board/examples). Use when starting any project that needs images, when the user says "visual style", "brand aesthetic", "image style", "visual identity", "how should our images look", "build visual brand", "define our look", or when /image-gen outputs feel generic because no visual style exists yet.

We split this skill into the rules it gives an agent

1 rule. 0 are common, 1 is distinctive, and 0 are very specific to this project.

  • 0

    Common

    Most of the 18 edited versions we read keep these.

  • 1

    Distinctive

    This author's own choices. Worth a look.

  • 0

    Very specific

    Tied to their project's names, files or tools. Probably skip.

“Common” is measured: kept by at least 6 in 10 of the 18 edited versions of this file we could read. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.

Keep what fits and drop the rest. Your version, ready for your agents.

When to use this skill

ALWAYS use this skill when the user mentions:

  • texture.wrapS / wrapT, minFilter, magFilter, generateMipmaps, anisotropy
  • colorSpace / correct handling of sRGB vs linear data maps
  • Creating DataTexture, CubeTexture, compressed GPU formats, video/canvas driven textures
  • PMREMGenerator from environment maps for IBL

IMPORTANT: textures vs loaders

StepSkill

Configure GPU Texturethreejs-textures

Trigger phrases include:

  • "Texture", "CubeTexture", "PMREM", "colorSpace", "mipmap", "各向异性"
  • "环境贴图", "数据纹理", "压缩纹理"

How to use this skill

  1. Classify texture dimensionality and format (2D, cube, depth, compressed, data).
  2. Color pipeline: set colorSpace appropriately; normal/roughness maps are non-color data.
  3. Sampling: choose filters; enable mipmaps when minification occurs; consider max anisotropy.
  4. PMREM: feed env map through PMREMGenerator per docs; assign result to scene/env/intensity paths as required.
  5. Video/canvas: understand update needs each frame for VideoTexture / CanvasTexture.
  6. Disposal: dispose() textures when replacing to free GPU memory.
  7. KTX2/Basis: transcoder wiring belongs in threejs-loaders before this step.

See examples/workflow-pmrem-env.md.

Scope

  • In scope: Core Textures + PMREMGenerator; sampling and color pipeline at texture level.
  • Out of scope: Loader configuration; post-processing passes that sample buffers (threejs-postprocessing).

Common pitfalls and best practices

  • sRGB albedo in linear workflow without proper colorSpace looks wrong next to renderer output.
  • Non-power-of-two textures have mip/wrap limitations unless padded.
  • Forgetting texture disposal on hot reload leaks VRAM.

Documentation and version

Texture classes and PMREMGenerator are documented under Textures and PMREMGenerator in three.js docs. Compressed and KTX2 paths often depend on threejs-loaders for transcoder setup before this skill applies.

Agent response checklist

When answering under this skill, prefer responses that:

  1. Link Texture, DataTexture, CubeTexture, or PMREMGenerator as appropriate.
  2. Tie colorSpace / filtering to threejs-renderers output and threejs-materials maps.
  3. Send Draco/KTX2 decoder wiring questions to threejs-loaders first.
  4. Emphasize dispose() when replacing env maps or large atlases.
  5. Mention Global constants only when wrapping/filter enums matter.
