Some screenshots from the glumpy examples directory.

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 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

Surface elevation

This example shows a 10x10 numpy array represented as a heightfield that is generated entirely on the GPU (using a default mesh).

Sources

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 !

Sources

Mandelbrot set

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

Sources

Klein bottle

Just because we can ! This example demonstrates parametric surface generation and visualization with uv mapping.

Sources

Quiver plot

Using GPU power, we can litteraly draw a quiver plot using a single quad. Adapted from Morgan McGuire original idea on shadertoy

Sources

Projected frame

Pixel perfect anti-aliased projected frame drawn by the GPU using a single quad. This can be adapted to any projection actually.

WIP

Reaction Diffusion

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

Hello world !

Text rendering uses both regular textured glyph with higher quality and signed distance fields. Glyphy to follow soon (hopefully).

WIP

Post processing filters

Post-processing is applied through python context manager. This example combines two filters to produce Gaussian blur.

Sources

Colormaps

Most colormaps can be computed just in time within GPU. But color lookup tables are also available through 1D textures.

Sources

UTF8 Terminal

This is a fast & failsafe terminal that allows to quickly display information on screen. It uses the UCS 6x13 bitmap character sets.

Sources

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.

Sources

Smoke simulation

Porting the fluid simulation from the little grasshopper, this example shows a very nice smoke simulation using GPU Eulerian approach.
