Radial Shear Node

Description

Applies a radial shear warping effect similar to a wave to the value of input UV. The center reference point of the warping effect is defined by input Center and the overall strength of the effect is defined by the value of input Strength. Input Offset can be used to offset the individual channels of the result.

Ports

Name	Direction	Type	Binding	Description
UV	Input	Vector 2	UV	Input UV value
Center	Input	Vector 2	None	Center reference point
Strength	Input	Vector 1	None	Strength of the effect
Offset	Input	Vector 2	None	Individual channel offsets
Out	Output	Vector 2	None	Output UV value

Generated Code Example

The following example code represents one possible outcome of this node.

void Unity_RadialShear_float(float2 UV, float2 Center, float Strength, float2 Offset, out float2 Out)
{
    float2 delta = UV - Center;
    float delta2 = dot(delta.xy, delta.xy);
    float2 delta_offset = delta2 * Strength;
    Out = UV + float2(delta.y, -delta.x) * delta_offset + Offset;
