A small selection of screenshots from the VisPy examples directory. More to come soon!

Fireworks

This example demonstrates simulation of fireworks using point sprites and has been adapted from the OpenGL ES 2.0 Programming Guide.

Spiral galaxy

This is a simulation of a galaxy using the density wave theory as explained by Ingo Berg. All simulation details can be found on his site.

Voronoi diagrams

This example shows dynamic Voronoi cells based on an old technique where the hardware is used to compute the diagram using 3D occluded cones.

High-frequency signal

This example explains how to plot high-frequency functions by resampling the signal. More details on the Syntopia website and Shadertoy

Point cloud

This example shows a 3D cloud of a million anti-aliased and stroked points animated in real-time. Most of them are hidden though !

Mandelbrot set

The mandatory Mandelbrot set computed in the GPU with single float precision even tough double precision through emulation is possible.

Reaction Diffusion

This example simulates a Reaction diffusion using Gray-Scott model largely inspired from this great site that gives all the details.

Realtime signals

From an idea by Cyrille Rossant, this example shows 320 signals with 10,000 points each. Each signal can be zoomed in/out individually.
