WeirdTruchetNewKeyboard

This Fuse is based on the Shadertoy 'Weird Truchet | New Keyboard' by byt3_m3chanic. © byt3_m3chanic (CC BY-NC-SA 3.0). Conversion to DCTL and encapsulation into a fuse done by JiPi. See ShaderOfTheWeek for more fuses in this category.

Once again two shaders published in one week in this section :-)
There was a problem with the fwidth function, which does not exist in DCTL and so a simulation is necessary. But here an interesting effect occurred. When the resolution was changed, the shader image was blurred from the outside to the inside. A rounding error was the cause of this. The effect can be made visible with the "off" parameter.

Have fun playing

Description of the Shader in Shadertoy:

Got this tiny Corne knock-off type keyboard from Amazon - 36 key

So this is me trying to code a shader, and memorize the key combos for the special/math chars.
