CatGo v1.4.8

CatGo 1.4.8

CatGo 1.4.8 restores database search and completes the shared WebGL/WebGPU
rendering work for periodic structures. Standard rendering and Large System
Performance Mode now use the same authoritative atom, bond, boundary, camera,
and visual-state data while retaining the WebGPU fast path for large structures.

Highlights

• Consistent periodic structures in both rendering modes — standard WebGL
  and Large System Performance Mode now agree on atom positions, bond geometry,
  periodic boundary images, lattice vectors, colors, radii, shading, camera
  orientation, and the axis gizmo.
• Database search works again across the app and VS Code — Materials
  Project, OPTIMADE, and PubChem searches have been updated for current provider
  APIs, pagination, and extension-host routing.
• Large System Performance Mode remains WebGPU-accelerated — the shared
  rendering contract removes visual drift without replacing the WebGPU fast
  path with the standard WebGL renderer.

Fixed

Structure rendering

• Fixed missing or extra boundary atoms, incomplete boundary bonds, dangling
  bonds, and transient long bonds after physical supercell expansion.
• Fixed atom and bond placement differences when toggling Large System
  Performance Mode, including 1× and 3× periodic/supercell views.
• Aligned bond thickness, endpoint colors, atom overlap, lighting, depth cueing,
  background color, lattice vectors, camera transforms, and gizmo placement.
• Kept atom movement, selected-atom rotation, camera motion, and visual-setting
  changes live while the WebGPU overlay is active.
• Fixed replica picking and the Three.js WebGL context failure reported as
  TypeError: error2 is not a function.

Database and VS Code search

• Uses the official Materials Project REST summary endpoint when an API key is
  available, including formula and element queries, pagination, totals, and
  structure conversion.
• Falls back to the official Materials Project REST route when its OPTIMADE
  endpoint returns no structures.
• Resolves OPTIMADE child-provider URLs and /v1 bases correctly, preserves
  pagination metadata, and avoids unavailable or misrouted providers.
• Adds reliable PubChem pagination and emits relative VS Code webview asset URLs
  so bundled WASM and worker files load from the extension package.

Upgrade notes

• No project, structure-file, or workflow-data migration is required.
• Large System Performance Mode still requires WebGPU; systems without WebGPU
  continue to use the standard viewer fallback.
• Configure a Materials Project API key to use the official MP REST results.
