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.

i'm not sure i understand what you are trying to do.
could you please give us some more information?

Don't know what [colorsquare] is... Are you using GEM?

i don't know if this changed in the last version of gem, but the current name for the object is [colorSquare]. it draws a simple square with the option of giving different colors to each vertex. in this way you can get a neat gradient effect all over the surface.

[pix_data] will give you the value of a specific pixel in an image or vid. Is that what you need?
