Circular countdown animation in SceneGraph?

Archived

Hi all

I’ve done some searching of the forum and haven’t found a solution to this.

Does SceneGraph support this type of circular countdown animation?

The rotation is easy enough with the FloatFieldInterpolator node. The issue is you can’t apply a mask (to hide the part of the circle image at the top of the rotation) that is supported on all devices. From the docs: “MaskGroup nodes do not work on all Roku players (specifically, MaskGroup nodes only work on players that support OpenGL).”

Or is there another way to achieve this animation?

Thanks

The Hulu Roku app currently achieves this as part of their countdown during advertising.

They’re doing it using 4 segments,
