We are still working on the Frontend Documentation, as this will be configurable via the Config Builder. Essentially, endpoints on aLED Strips have a layer associated with them. In Firmware v1.1, those layers have a (currently fixed) opacity assigned to them. The opacity can either apply to the full segment or be interpolated based on a configured mask (this mask can also slide—this is where the animation aspect comes in).
Gradients can therefore be achieved by stacking two endpoints over the same segments: one base endpoint and one with ascending (or descending) opacity above it. This creates a gradient effect, as the color gradually transitions from the base endpoint’s color to the gradient endpoint’s color.
Example:
Base EP: Green
Gradient EP: Red and Blue
Animated Gradient:
Here’s a snippet of the (work in progress) documentation:
