Concentric Shapes (and Stroke)
I saw this hanging in a tweet, and I just couldn’t resist!
Watch the demo for ideas.
Concentric Shapes is a tool for the artist in you. It’s very basic but can be exploited for a wide range of effects.
What kind of options are there?
- Nine Shapes: Circle, Square, Triangle, Diamond, Pentagram, 5-pointed Star, Hexagon, Octagon, and Heart
- Overlay Color
- Blend Mode (Normal, Multiply, Burn, Add, Dodge, Overlay, Light and Alpha)
- Shape Scale (distort the original shape in X and Y directions — Z won’t make a difference)
- Shape Transform – changes the shape towards a circle except for the Circle shape which transforms to a square.
- Shape Rotation – rotates the orientation of all shapes
- Align Angle to Path – rotates all shapes on the circle paths to the tangent on the circle at its location
- Path Angle Offset – separately rotates all the path shapes from the original center shape
- Offset Path Position – slides all path shapes along their path from -360º to +360º for the innermost path. Subsequent paths rotate at half the rate as the path before it. Keyframe this for an amazing animation.
- Feather will soften the outline edge of the shapes
- Falloff will change the “easing” effect of the feathering.
- Center is the position of the middle of the concentric shapes
- Rotate All is a uniform rotation of the effect
- Scale All will scale the entire effect.
When using the Alpha blend mode option, use with Stroke (FCPX 10.4.9 or higher only) to outline the shapes.
- Stroke Type offers 3 different styles: Color, Gradient and Outline Gradient!
—changing the Stroke Type will change the parameter list from color picker to gradient designer
- Position: Outside, Centered and Inside. Use inside if you want to have sharp points around the shape.
- Offset will displace the outline from the actual Alpha edge
- Threshold can be used to determine at what point the outline is drawn based on relative opacity of effects that create alpha (and with the Fade parameters below).
- Fade Inside will “erode” the inside (alpha/solid) edge.
- Fade Outside will “erode” the outside edge.
- Fade Width will “burn” both edges.
- Fade Falloff affects the easing of the feathering/fades.
- Hide Source will turn off the solid portions of the image and leave only the Stroke effect!
- Blend Mode will only work with how the Stroke interacts with the solid, non-transparent portions of the image when it “draw” over the source (as when the Offset is negative or the Position is Centered or Inside.)
- Mix is an Opacity workalike.
