viznoir
Gives Claude direct access to VTK's rendering pipeline for scientific visualization without needing ParaView or a display server. You get 22 tools covering inspection, rendering, filtering, animation, and composition. Point it at OpenFOAM, VTK, CGNS, or any of 50+ mesh formats, then ask for isosurfaces, streamlines, volume renders, or cinematic animations. The physics layer understands vortex detection and stagnation points, so it can auto-annotate features in 3D space. The compose_assets tool builds multi-panel physics stories with LaTeX equations. All output is headless PNG, WebP, MP4, or glTF. Useful when you're iterating on simulation visualization in a chat interface instead of clicking through a GUI.
