Swipe to View
Mist, Blur, Red-Violet Sky
Swipe over the river scene. Sky, river, distant trees and hills blur, turn violet, red then blue again. The distant horizon lights up with lightning.
Implementation
The background was modeled and rendered with 3ds Max, then mapped to the inside of a sphere. The final rendering modifies color channels wit a WebGL (GLSL) shader, in response to touch or mouse movement on the canvas.
