## What it is
Glumpy is a Python library for fast, scalable scientific visualization built on a natural interface between NumPy and modern OpenGL. It provides GPU-accelerated rendering of large datasets with real-time performance for millions of points.

## Use cases
- render millions of data points in real time
- visualize numpy arrays on the GPU
- simulate and display a spiral galaxy
- render surface heightfields from numpy arrays
- draw high-frequency signals with GPU multisampling
- compute and display Mandelbrot fractals
- render SVG graphics with minimal GL calls

## When to choose
- you need hardware-accelerated scientific visualization in Python
- your datasets are too large for matplotlib to render interactively
- you want direct NumPy-to-OpenGL integration with custom shaders

## When to avoid
- you need simple static plots or charts
- you want a high-level plotting API without writing shaders
- you need a maintained library with frequent updates and broad community support

## Facets
- artifact type: library
- maturity: maintenance
- function: data-visualization, graphics, image-processing
- domain: data-visualization, graphics, data-science
- platform: python, cross-platform
- tags: opengl, numpy, gpu-rendering, scientific-visualization, shaders, glsl, scientific-computing, desktop
