Ghibli Desktop & Mobile Clouds

Features

The COZY Ghibli clouds are a completely different way to display clouds in the COZY ecosystem. In the Ghibli style clouds are made of a few voronoi noise functions that are spliced together using two algorithms called cohesion and sphere distortion. The only difference between the Desktop and Mobile variants is that the Desktop variant has two layers of clouds for fuller skies.

Cohesion

Cohesion groups nearby noise bubbles together to make noise clouds that have a nice arranged quality to them. From values of 0-1 cohesion is increasing resulting in larger groups condensing into larger clouds.

With a cohesion level of 0, no clouds are grouped resulting in very small, randomly placed clouds

Cohesion of 0

Whereas with a cohesion level of 1 clouds are tightly packed into large groups.

Cohesion of 1

At values above 1, the clouds bleed over into the empty space resulting in clouds appearing in the negative space which has an interesting effect to it

Cohesion of 7

Sphere Distortion

The COZY weather sphere is just that: a sphere. We can leverage this fact to create even more interesting shapes if we exaggerate this shape in our cloud shader.

At values of 0.25, the sphere distortion has no effect and clouds are displayed normally

Sphere Distortion 0.25

As you lower this value, clouds start to blur cylindrically and appear larger and more scattered above the horizon

Sphere Distortion of 0.05

However as you raise this value, the clouds distort spherically resulting in flatter looking clouds that scatter on the horizon

Sphere Distortion of 0.85
