| Oct 5, 2015 at 11:14 | comment | added | Kroltan | Separate XYZ just splits the three components of the vector (in this case, the UV vector), since we only need to operate the horizontal axis. Since UV coordinates' range is [0; 1], I use Multiply to map it to the range [0; 100]. The number 100 is the amount of horizontal pixels. The Modulo 1 just makes the output of Multiply wrap around the range. Together, Multiply and Modulo just makes the value loop 100 times in the range [0;1] throughout the UV. This is fed into the ColorRamps to give a color output to each sample. Example visualization: gyazo.com/185adb745fc3480c1c89fd8032388cda | |
