NoiseRings

NoiseRings is a noisy emanating ring effect for Unity adapted with permission from the VR music video experience Chorus. Tested with Unity 2018.3.0f2.

Usage

An example is provided in Assets/Example/ExampleScene.unity. Attach a NoiseRingSource component to the GameObject you would like the noise rings to emanate from. For the NoiseRingSource to render correctly the UpdateShaderGlobals component must be attached to a GameObject in the scene. The noise ring animation can be triggered by calling Trigger() on the NoiseRingSource.

Settings

Name	Type	Description
Number Of Segments	int	Number of segments in the generated ring mesh. Increase this value if the rings appear too jagged.
Number Of Rings	int	Number of rings to emanate when the animation is triggered.
Radial Offset	float	Radial distance between the rings when emanated. This allows you to control how far apart the rings appear to be spaced. Note that the distance will shrink as the animation progresses and the rings will converge at the end.
Line Texture	Texture2D	Texture to use for rendering the ring lines. The texture will be stretched horizontally around the circumference of the ring.
Color	Color	Line color.
Multiplier	float	Line color multiplier.
Line Width	float	Line width. This is scaled with the transform's z scale value.
Noise Scale	float	Scale of the noise applied to the rings. Higher is bumpier, lower is smoother.
Noise Height	float	How much the noise affects the height of the rings.
Detail Noise Scale	float	Scale of the detail noise applied to the rings. Higher is bumpier, lower is smoother.
Detail Noise Height	float	How much the detail noise affects the height of the rings.
Speed	float	Speed at which the noise changes.

Animation Settings

Name	Type	Description
Animation Duration	float	Total duration in seconds for the animation to complete after being triggered.
End Radius	float	The final radius the rings will reach and converge at.
Intensity Curve	AnimationCurve	Curve that determines how much the noise affects the rings as they progress outward.
Max Height	float	Maximum height above the ground the rings will reach.
Height Curve	AnimationCurve	Curve that determines the height of the rings relative to the max height as they progress outward.

Public Methods

Name	Return Type	Description
Trigger()	void	Triggers the animation.
EndAnimation()	void	Ends the animation early.
AnimationDuration()	float	Returns the animation duration.
