## What it is
Viser is a Python library for web-based 3D visualization aimed at computer vision and robotics. It provides APIs for rendering 3D primitives, building GUIs with sliders and buttons, and interacting with scenes from any browser, including over SSH.

## Use cases
- visualize point clouds and meshes from a python script
- inspect COLMAP reconstructions in a browser
- debug robot URDF models interactively
- view gaussian splatting renders remotely over ssh
- build a quick GUI with sliders to tune algorithm parameters
- render images from programmatic camera poses

## When to choose
- you need interactive 3D scene visualization from Python without installing desktop apps
- you work remotely over SSH and want browser-based visualization
- you want to combine 3D scenes with custom GUI controls in Python

## When to avoid
- you need publication-quality static plotting rather than interactive 3D scenes
- you require a native desktop viewer with GPU-local rendering
- your project is not in Python

## Facets
- artifact type: library
