Color Wheel
#shader #codepenchallenge #cpc-color-wheel
Screenshot of my shader on CodePen, showing eight cards arranged in a circle like plates, glowing in metallic colors ranging from red to purple, blue, turquoise, green, light green, yellow, and orange. The background is reflected in the plates, which have decorative edges.

That looks like a lot of fun! I'm glad I could contribute to the amusement with this shader. Thanks for the great challenges, Raph, and for taking the time to do this! @sableraph.bsky.social www.twitch.tv/videos/25721... #wccchallenge
This is a screenshot from Raphaël de Courville's Twitch stream of the latest Weekly Creative Code Challenge, in which he tries to fend off my shader, which depicts a pair of floating lips, facing him and hovering above him.

Self-Reflect #shader #codepenchallenge
The image shows a spoon on a wooden table inside a church. The spoon reflects both the church and itself. This image was created using a WebGL fragment shader and a technique called ray marching for a CodePen challenge on the theme of reflection.

The image shows a space anomaly surrounded by stars. The anomaly consists of spiral-shaped, semi-transparent arms. It possibly consists of several elements that appear to range from bright blue to yellow. The original fragment shader can be found in my profile on codepen.io/atzedent.

Retro Waves #shader #wccchallenge
This image was made using a shader. It shows a cloudy moon in the sky, behind snowy mountains, reflected in a wavy sea, with three birds flying in the center towards the mountains. The colours go from dark blue to bright red and all the way to the white of the snowy mountains.

Moon View #shader
View from a spaceship orbiting the moon of an alien planet. On the upper left is a gas giant in red with yellow clouds. Same shader but with a color filter. The same shader, this time with a hatching filter.

Solar Neighborhood #shader
The shader shows a rather dark abstract landscape scene in shades of gray with a surreal cloudy sky behind a rocky terrain with an erratic boulder on the left and a building made of three parallel slabs glowing red like lava on the right.
