Hi,

I'm trying to find a way of reading out specific points in online rendered gradients.

I'm using [colorsquare] and basically want to read out a number of points spread inside this rectangle, e.g. 6 equally spaced points where I'd pick the local color, and later send it to a series of LEDs.

Yes, you could say that is basically the same as reducing the resolution of the gradient (just taking a 2D line is fine with me) to, say 6 steps. But I'll be mixing colors in realtime creating various complex meshes. I guess I should make some way of reading out particular points in the array of that updated color mesh... Anyone who can help me with that?

Thanks, siziw.

Hi,

1- For conversion between colorspaces (hsv to rgb or vice-versa) you can use [hsv2rgb] and [rgb2hsv], which is I guess what Sumidero's second link suggests.

2- I'm looking fo something similar, be it that I'm trying to find a way of reading out specific points in rendered gradients.
