Sphere Mask Node

Description

Creates a sphere mask originating from input Center. The sphere is calculated using Distance and modified using the Radius and Hardness inputs. Sphere mask functionality works in both 2D and 3D spaces, and is based on the vector coordinates in the Coords input. These vector coordinates can either be 3D like world space position, or 2D like UV coordinates.

Ports

Name	Direction	Type	Binding	Description
Coords	Input	Dynamic Vector	None	Coordinate space input
Center	Input	Dynamic Vector	None	Coordinates of the sphere origin
Radius	Input	Float	None	Radius of the sphere
Hardness	Input	Float	None	Soften falloff of the sphere
Out	Output	Dynamic Vector	None	Output mask value

Generated Code Example

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

void Unity_SphereMask_float4(float4 Coords, float4 Center, float Radius, float Hardness, out float4 Out)
{
    Out = 1 - saturate((distance(Coords, Center) - Radius) / (1 - Hardness));
}
