OVITO → Blender Visualizer (PC2 + Dupli-Verts)

Goal: Play OVITO/LAMMPS dumps in Blender 3.6 with per-frame updates, using a vertex instancer and a template sphere.
File: blender/ovito_viewport_anim.py

Features

• Reads multi-frame LAMMPS dump (OVITO format).
• Builds one-vertex-per-atom mesh and instances a template object.
• Updates vertices per frame; playback in viewport.
• Lock interface during render to avoid instability.

Requirements

• Blender 3.6
• A LAMMPS/OVITO dump file with ITEM: headers.

Quickstart

1. Open Blender → Scripting → load blender/ovito_viewport_anim.py.
2. Set ruta_archivo to your dump path.
3. Run script. Play timeline.

Notes

• This script focuses on viewport animation. For stable Cycles renders, bake to PC2 and instance via Geometry Nodes in a separate step.
