is there a function available to convert a temperature value (range 10° Celsius up to 90°) to a RGB value representing the colour ? The calculated colour / RGB value shall be used to controll a LED.
The range node might work
A quick search of the forum reveals....
Nice, I as going to just set up a ratio, since RGB is 0-255 and Celsius is 0 to 100. Of course you could weight the ratio per color by percentage, to get some nice colorization. So a nice red, that is not just all red, could be red 75%, 10% green and 15% blue, once you establish the ratio for red for example.
Perfect, seems to do what I want, thanks!
