Details

A reimplementation of the Polygon Shredder using instancing, adding some of the features I was missing from the first version: different geometries to move around and a bit of postprocessing.

The curl noise is perform in two textures, ping-ponging the simulation. Both textures are used as current and previous positions to reorient the instanced mesh. Shadow mapping, diffuse and specular lighting is applied. A post processing pass of bloom, fxaa and vignette is finally applied.

p>Built with three.js, Maf.js and dat.gui.

Code available on GitHub.

Controls

Play with the params:

• Persistence: dispersion of the curl noise.
• Speed: speed of the particles.
• Decay: life of the particles.
• Animate: toggles animation.

• Mesh: choose the mesh to draw as particles.
• Scale: global scale of the particle.
• ScaleX: scale of the particle in X axis.
• ScaleY: scale of the particle in Y axis.
• ScaleZ: scale of the particle in Z axis.
• Squashiness: how it deforms when moving fast.
• DrawRange: control how many particles to draw.
• Post: toggle post processing.
